Hi, Can anybody help me with a Rx-Tx 433 comunication? I tried the manchester library, but it does not work. If I connect the boards by wire, then I get the message sent.
But it won't work over the RF. I am using my own RF modules (not from mE).
The modules are working fine (tested with the same pcbs, only programmed by somebody else) So, basically I have 2 boards built and programmed by somebody else. They work fine (perfect). But I want to add some more bits to these, so I need to do my own programming. Can't ask the former programmer, (unless I get help from somebody that can talk to the dead). So it seems easier to ask here for some help. I ONLY have basical programming skills. And I feel this RF communication is over my head.
If nobody is willing to help me for free, then tell me your price. Hi olivia I think that your problem would be in the initial syncronitation. I mean when you use wire comunication you dont need it but in wireless yes. Try to send a string of several equal byte in order to receptor will syncronice first.
For example Transmiter send 0x33 0x33 0x33 0x33 0x45 you receptor might not received the first 0x33 but yes some 0x33 and finally syncroniced. The receptor is waiting the start of frame, in this case 0x43. I recomend you send minimum 20 (0x33) before to send the inicial frame caracter. I hope that it can help you. Hi, and thank you for reply.
Braus There is no need for any 'special' kind of interface between microchip PIC and RF module. Like I said, the boards I am using are already working FINE (in RF link). I just want to modify both the Rx & Tx software to do what I want (not what was first designed). And to make sure I get it right, at the beginning I am trying to replicate the original code, to make the boards do what they are already doing in the first place (with the original code); and when I get them working then I can modify/add my other subroutines to make it work the way I want. I do not have the original source code (only the hex files), so I need to build one from scratch. (just a thought, is there a des-assembler which can reverse engineer the hex file to a source code?
I could give it a try) I do feel that part of the problem is the syncronisation, like alejandroflamerich said. Because it is working with a wire link, but not in RF link. But I feel that the syncronisation only, is not going to solve my problem. You see, I will have more than one Tx transmiting, and only one Rx receiving.
So, if I have 20 transmmiters trying to send some data, I need some kind of CRC/Checksum to validate the incomming string. With the old software I have tested even 100 transmitters (working all at the same time), and one receiver, and I have never lost a single packet. Works perfect. My problem is that I have never used CRC/Checksum and I do not know how to implement it in both Rx & Tx I do not even know if the original programmer has used the manchester library to do it. Lots of people say the manchester protocol is an 'elegant way' of transmmiting data via RF. The way I see this manchester protocol is that the original data is doubled (at least), so there is even more chances of interfering. When I say data is doubled we know that manchester protocol transforms a 1 to a 01; and a 0 to 10; It could be the other way, it does not matter.
What matters is that 8bits of data becomes 16bits of data (so it doulbles it), and then add some preamble etc. So in the end I have 200 transmitters sending lots and lots of rubbish.
Of course for the begining I only try ONE transmitter, so there is no interference from the others. But still is not working. So, I am asking is there another 'elegant' way of transmiting data without double it? A string example from the working software is like this: 551000046C000000249E So, double this, add 200 transmitters and there's the rubbish interference. I am not saying is not working (like I said I do not know if he used manchester protocol).
I am just saying this is no way an 'elegant' way of RF communication. The only reason I can see why they invented this protocol, is to eliminate false/corrupt data. If you receive 3 bits of the same kind ( 000 or 111), at any time, then the data is corrupted. Example: I want to send 000 the manchester protocol transforms this into 101010 and then sends it.
The receiver receive 101010 and the manchester protocol transforms it back to 000. So at the receiver there is no 3 bits the same one after another (even I sent that in the first place). Same with 111 This will become 010101 If I want to send 100110 that will become 10 So again there is no way there is going to be 3 bits the same in a transmision. So I do not see the reason of doubling the data string, just to make sure the received string is not corrupted. There must be other simpler and more elegant way of checking the incomming data. I heard that CRC/Checksum is taking a lot of processing power from the pic. Maybe this is the only reason why they choose to double the data (and create more chances of interfering).
I just do not know. Anyway for now I want to make my boards work (manchester or not). Thanks for any help.

If you receive 3 bits of the same kind (000 or 111), at any time, then the data is corrupted. This is not true, With this kind of coding you embed the timing into the protocol, Use the preamble to get the bit time, start of package and settle the AGC on the receiver, then it's easy to know if it is a interference when a bit is missing. Another positive thing is increased range.
Is there a way to see the source code for this manchester library? Or for that matter for any library code in mE? If I could see how it works I may be able to understand why I have problems (and not just me, I have seen on this forum lots of people having same problems with manchester protocol). Now PeterA says about timings.
( I ONLY have basical programming skills). How do I adjust the timing (if necessary). And it may be necessary to adjust it, because the Rx has a 8MHz Xtal, and the Tx has a 1.4MHz RC. (I repeat it works perfect with the original code). So this may be the problem. But I have changed the RC to a 8MHz Xtal just to see if it solves the problem. Still is not working.

If you use ME libs you can't do much about it, ME use a low baud rate so even the RC osci should be good enough. Making your own Manchester routine for sending is easy but the receiver part is a bit tricky, To do a good Manchester lib you need timer skills.
I have one i wrote a few years back 'Not saying it's a good one but maybe it's a starting point', I will see if i can find it and post it here.

Hi Olivia Besides the data rate limits there is nothing wrong with the mE MAN library, you can prove this by going conducted (wire to wire), the problem you (and many others which blame mikroC) have is that when you go radiated (RF link) it all falls apart. This is because many people lack the skills required to make a successful RF link. Manchester coding, in simply terms only makes the data more robust. It does NOT control the RF link, you have to build that control around the Manchester coded data. The key as has been said, at the very least is to have a training pulse stream to achieve synchronisation between Tx & Rx units.
Testing the mikroC pro Manchester library with the supplied examples works perfectly conducted, which proves the encoding method! Next is to build the RF link control block. EDIT: the libraries are private and as such source code is not available.
Many people lack the skills I am one of those people, I admit it. Mince-n-Tatties are you one of the 'other' people who do not lack these skills?
If yes, and if you have already succeded in building a RF link, please tell me what skills do I need to learn, so I can make it work? OK, so manchester protocol does not control the RF link. I have to build this control, I understand.
But until I know how the manchester library works, this is an impossible mission (and I am no Tom Cruise to solve it). You say this is a private library, and other people say just add a lot of preamble to achive synchronization.
I am sorry, but this is no science, this is just fiction. It's like you blindfold somebody, give him a hammer and ask him to cross the road and hit the nail in the head.
You either remove the blindfold so he can do the job, or you put his hand over the nail so he can feel it, or you just hit the nail yourself. Which way do you want to help me??? I have to build this control, I understand. But until I know how the manchester library works, this is an impossible mission (and I am no Tom Cruise to solve it).
Tom Cruise actually has severe dyslexia so i doubt he would be of any help to you either. You really need to treat the (any) library as a black box, where you stick some known data in and you get the converted data out.
How many people drive cars? How many people know how the internal combustion engine works? Not knowing how it works does not stop you using it.
Hi Olivia, i have taken the mikroC Rx example included with mikroC pro 3.2 and converted it into label: goto format for you, although this is a method one would NEVER use in any real code,it serves to make the process much more understandable as the steps through the Rx loop are easy to follow with this layout. There are two LEDs added to the code which are used as indicators of 1. When a valid start byte is found 2.
After a valid start byte is found, another LED is used to indicate the good data being sent to the LCD. This is called 'label and goto' which i repeat you should NEVER use in C for a real end product!

How to Program a New TiVo Remote - Tips and Troubleshooting Welcome to weaKnees - The DVR Superstore and Repair Center Thank you for purchasing a new, genuine remote from weaKnees, the DVR Superstore. We are an authorized TiVo Retailer and all of our remotes are genuine, authentic parts. Specific VOX remote help is Power, Volume, Mute, Input Buttons All remotes must be programmed to work with your TV. Power, Volume, Mute, Input, will.not. work unless they are programmed. TV-specific buttons can be programmed using the TiVo on-screen instructions. To find those instructions, please see the chart below: TiVo Model Menu Path (From TiVo Central) BOLT Unified Entertainment System & Roamio Series DVRs Settings & Messages Remote, CableCARD, & Devices Remote Control Setup For Bolt, also see the in the section entitled 'Remote, CableCARD and Device Settings.'

For Roamio, also see Premiere Series DVRs, Series3 and earlier Messages & Settings Settings Remote, CableCARD, & Devices Remote Control Setup Also see: and these. Pairing an RF Remote (Roamio, Slide Pro, Bolt Remote) with your TiVo or Mini If you have an RF-capable TiVo remote (Roamio remote, Bolt remote or Slide Pro remote) and are having trouble setting it up in RF mode, please see.: if you need help pairing your remote, please see the 'TiVo Mini and Premiere Instructions' on. (Note that the instructions are for TiVo's Slide Pro remote but they apply equally to the remote included with your Mini RF.) If you need help programming your remote for your TV's volume, power, mute, please. To use the learning features of a Slide Pro Remote, see. For backlight instructions for a Slide Pro Remote, see. NOTE: If your remote is not adjusting the volume repeatedly when you hold down the volume up/down button, this is NOT a problem with your remote. You simply need to find a different remote programming code for your TV.
Some codes require one press per volume tick (up or down); other codes allow you to hold the button down. Just go through the remote instructions again and choose a different code. How to set up your RF-capable TiVo remote in RF mode: All TiVo remotes that have RF capability will flash an yellow light if it is set up in RF mode. If you press TiVo buttons on your remote and the light is glowing RED, then you are not set up in RF mode. To set the remote up in RF mode, follow the instructions below. If you have a Bolt, TiVo Roamio, Roamio OTA, Roamio Plus, Roamio Pro or TiVo Mini with serial number starting A93, follow these instructions: Prepare the DVR for pairing Navigate to the Remote Control Pairing screen: TiVo Model Menu Path (From TiVo Central) BOLT UESs & Roamio Series DVRs Settings & Messages Remote, CableCARD & Devices Remote Control Setup Remote Control Pairing Mini Settings & Messages Remote & Devices Remote Control Setup Part 5: Remote control pairing The UES/DVR is now in New Pairing Mode and should automatically pair with any RF remote within 3 feet. If it does not, manually pair the remote.
Manually Pair the RF remote Press and hold the TiVo+Back buttons until the activity indicator light turns red. The remote control will then send pairing requests for 30 seconds (as indicated by the flashing amber activity indicator). The remote will pair with any DVR that is accepting pairing requests. NOTE: If pairing is unsuccessful, the remote will return to its original state (either paired or unpaired). If you have a TiVo Premiere, Premiere XL, Premiere XL4 Premiere Elite or TiVo Mini with serial number starting A92, follow these instructions: 1) Plug the remote's dongle into the TiVo's USB port and hold down the button for a few seconds until the light starts flashing. 2) Hold down the TiVo and Back buttons on the remote for a few seconds until the light at the top of the remote illuminates and is solid. 3) Wait for the remote to pair.
Once it does, the remote will now flash yellow, indicating that it is in RF mode. TROUBLESHOOTING RF REMOTE PAIRING The amber light on my remote blinks for several seconds whenever I press a button In the event that you have paired an RF remote to your Roamio Series DVR, but you later have to replace the remote, the new remote will not yet be paired to your DVR. It will automatically revert to IR mode. When this is the case, the amber light will blink for 30 seconds after every button press, but the functionality of the remote will otherwise be unchanged. To make the blinking yellow light stop, and then pair the remote to your DVR for RF functionality:. Press TiVo + Red C until the TiVo mascot's antennae blink red. Now press any button and confirm that the TiVo mascot's antennae blink red with each button press (it should no longer flash amber).
Press the Live TV button. Hindi mp3 songs free download. Press Clear, Enter, Clear, 221, Clear (this will send a signal to clear any RF pairings on the DVR). Hold down TiVo + Back on the remote until the TiVo mascot's antennae blink amber (the remote is now ready to pair with the DVR). Now press any button on the remote and confirm that the TiVo mascot's antennae blink amber with each button press. The remote is now paired in RF mode with the DVR.
Global reset The Global Reset function unpairs the RF remote from the paired UES/DVR, then clears any other remote settings, such as IR codes for your television or other A/V device. Use this function to unpair a remote and return it to the out-of-box settings. IMPORTANT: You will need both the paired RF remote and the UES/DVR to perform a global reset. If your paired remote has been lost or damaged, you will need to use a new remote in IR mode to put the UES/DVR in a pairing state, then pair the new remote to the UES/DVR.

Specific Troubleshooting Instructions for VOX Remotes: If you are having problems getting your VOX remote to pair with any unit, first try this: Navigate to your TiVo's remote pairing page, and once there, put your remote in pairing mode also by holding TiVo and Back until the light goes red. Then make sure it's very near the TiVo - even sit it right on top. Test by pressing the Microphone button. If that doesn't help, try this: Step 1 - Put Remote in IR mode by pressing TiVo and C until you get three red flashes. Press LIVETV to test, aiming it right at the TiVo. Step 2 - Still aiming right at the TiVo, press these buttons: Clear - Enter - Clear - 2 2 1 - Clear (you likely won't see a visual indcation of this action) Step 3 - Pause for 10 seconds, then press Channel Up. You should see a red and a yellow flash.
Wait a couple of seconds and press Channel Up again and the light should flash yellow instead of red. Test - Test by pressing the Microphone button. WeaKnees.com is not affiliated with TiVo Inc.

I agree with others that at 6 tuners I can't imagine why you would need more than one roamio plus or pro in the same rack. And would like to know more. However I have used 2 tivo's in the same rack before - not since series 3 hardware - and much older harmony hardware.
So I'll give what I know for that and maybe you can adapt it to your craziness that your building. Also a warning. No regular user will be able to figure this out, especially if there is a break down of some kind (wrong input, missed command, etc) so consider this type of setup power user only. As someone said the older tivo remotes had an A and B switch so you could do just this task - you will need such a remote in order to start this. Use this to program the TiVo boxes to a and b and verify that they work in that fashion with the original remote. You will then need to create two separate devices on your harmony TiVo A and TiVo B and then instead of using the codes that can be auto downloaded - you will have to manually learn each button individually for both A and B using the original switched remote. You can than create activities (macros) using TiVo A and B so for example mine used to be 'watch TiVo' (this would use A and turn my tv to input 1) and than I created 'watch overflow' (this would use B and turn my tv to input 2) Hope that makes sense - can't wait to hear about what your building!
I do have some extra advise before I go. The roamio / mini platform has excellent streaming capabilities (moca or Ethernet) - instead of putting 2 in a rack I would personally just put one in another room (even if there is no tv there) - program it online or from the app and than watch remotely - it will save time and stress. The only real important management you will have to do is ensure to record premium programming (HBO, showtime, etc) on the main box as it doesn't always play as nice with the streams) The.
I wanted to thank everyone for their replies. To answer some questions. I was attempting to avoid having any components in any rooms aside from the TV and a control unit for audio on the wall. (with something like ) so to that end I was trying to have all my Minis and the host Ramio in one cabinet with the Audio control and possibly the video switcher along with several other home control systems and network controls.) from what I'm seeing I'll need the Minis at the destinations which has a small footprint and can probably be mounted behind the tv.
