Also, what’s the signal look like at 1. Don’t know what’s really happen with my encoder.

If your data is riding on the noise at 1. I’d use a 1uf or even a. Check your comp drawing. Originally Posted by mackrackit. What kind of comparator circuit are you planning? But before I accomplish that, I want to test my RF module whether it’s function or not. It says the output come with noise and it seems like the main problem. Do you have any oscilloscope? I will suggest you to test it without the RF modules for now.

Probably the internal comparator could be used here. But It’s fine to me. Without any spec of your module, it’s a bit hard.

TE pin should be tied low too unless the oscillator won’t run.

For your Information, I put 1M resistor between these 2 pins. If you do not believe in MAGICConsider how currency has value simply by printing it, and is then traded for real assets. Adding another comparator might be useful for educational purposes but is of little practical value IMO.

Pause 50 ‘ Debounce getkeyu: Thanks for all the advice Now my Rx module works fine in a short distance around feet. Use the one for your frequency and even with out a good ground plane you should see improvement. I don’t know how to troubleshoot the problem because I’m new to this thing. Now I’m moving foward to send a data from my keypad.

Once the wire connection will work, i may suspect 2 other things. I also recommend sending 3 or more copies of each packet, including the wide sync pulse. Seems to be the one you’re using right? Join Date Mar Posts There’s no problem, only learning opportunities.

The uf cap is a bit much. Joe, seems you missed the underlined section I just use a small wire with length 10cm each for my Tx an Rx. Join Date Dec Posts 1, It is far simpler to use a relatively wide sync pulse followed by the data.

There’s a long long long way in between, i think you could try the Inverted mode first and then slow the baudrate, say bauds. Does it have an ADC that needs disabled?

Members who have read this thread: You should have a decent distance between the transmitter and receiver I think you ment to take the output of the rec to the inverting input, not ground. You can also try to add more Synk character at the begining of your transmission.

I just add 10k pull up resistor at Rx data pin and 10uF at Vcc. Once you have something workable, just add the modules. I wrote the code below.
