The time now is Dataseet Posted by Joe S. There is not much you can do with a comparator to reduce the noise. It says datwsheet output come with noise and it seems like the main problem.

Join Date Dec Posts 1, Without any spec of your module, it’s a bit hard. And in the schematic pin 3 of the LCD goes straight to ground. I see empty variables in the serout routine. Adding another datashdet not help. What kind of comparator circuit are you planning?

Page 1 of 2 1 2 Last Jump to page: So I use this simple program to test it but my LCD at the receiver board display nothing. Don’t know what’s really happen with my encoder. Try those with direct connection. Probably the internal comparator could be used here.

problem with sending data using RF module

See pics in POST 1. I don’t know how to troubleshoot the problem because I’m new to this thing. I just add 10k pull up resistor at Rx data pin and 10uF at Vcc. What PIC are you using?

In bimark case, the only output from the receiver is digital so the noise pulses will have the same amplitude as the data and the duration of the noise pulses are likely to be nearly the same as the bit period.

Join Date Mar Posts Steve It’s not a bug, it’s a random feature. I would suggest you to add a 10K pull-up resistor between Vcc and RA. You can also try to add more Synk character at the begining of your transmission. Maybe Joe has bifocals like me. OK, i’ll start a new thread later about how using the internal comparators.

I try to change the baud rate but nothing happens. Regards, -Bruce tech at rentron. But It’s fine to me.

TE pin should be tied low too unless the oscillator won’t run. Join Date Jul Posts 2, Once you have something workable, just add the modules. Now I’m moving foward to send a data from my keypad. When testing the com link with wires, do not forget to also connect datasheft ground between both circuits. Hook a pot up as a voltage divider with the wiper going to display pin 3. Is this xr3310a of it? I have tested a SAW controlled transmitter and superregenerative receiver from the same company.

Does it have an Himafk that needs disabled? It is far simpler to use a relatively wide sync pulse followed by the data. Use the one for your frequency and r3310a with out a good ground plane you should see improvement.

Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants – but debt is the money of slaves. There simply is no “Happy Spam” If you do it you will disappear from this forum. I think you ment to take the output of the rec to the inverting input, not ground. Originally Posted by mackrackit.

I think maybe the problem is from the antenna. The receiver can look for the sync pulse and only after receiving it, look for the data. There’s a load of noise indeed Thanks for all the advice Now my Rx module works fine in a short distance around feet. Do you have any oscilloscope? Hello Steve, Since I still receive noise.
