Members who have read this thread: You can also try to add more Synk character at the begining of your transmission.

But It’s fine to me. OK, i’ll start a new thread later about how using the internal comparators. There simply is no “Happy Spam” If you do it you will disappear from this forum. I just use a small wire with length 10cm each for my Tx dayasheet Rx.

It is far simpler to use a relatively wide sync pulse followed by the data. Please help me guys.

For your Information, I put 1M resistor between these 2 pins. Is there any chance for dataheet receiver to get the sending data clearly without noise If I connect the data pin to LM ? The decoder works fine but the encoder have a little bit problem.


What PIC are you using? Adding another comparator might be useful for educational purposes but is of little practical value IMO.

Maybe Joe has bifocals like me. When testing the com link with wires, do not forget to also connect the ground between both circuits.

Maybe the following link will help you a little bit http: I also recommend sending 3 or more copies of each packet, including the wide sync datasheeh. I’m really in between few things Without any spec of your module, it’s a bit hard. Once you have something workable, just add the modules. At least it’s work. I’m very poor with the coding.

The uf cap is a bit much. I will suggest you to test it without the RF modules for now. There is not much you can do with a comparator to reduce the noise. The dataslicer uses a comparator as I explain at http: Use the one for your frequency and even with out a good ground plane you should see improvement.


I’m curious is this data-slicer is ever squaring anything.

It says the output come with noise and it seems like the main problem. What kind of comparator circuit are you planning?

Now Homark moving foward to send a data from my keypad. Originally R3x310a by mackrackit. I would suggest you to add a 10K pull-up resistor between Vcc and RA. I’ll also suggest you to follow Dave’s post http: Seems to be the one you’re using right? Pause 50 ‘ Debounce getkeyu: Try those with direct connection. I have tested a SAW controlled transmitter and superregenerative receiver from the same company.

Actually I want to send a character using my RF module. Steve It’s not a bug, it’s a random feature. And in the schematic pin 3 of the LCD goes straight to ground.
