if I reduce control values to 1 or two, then it works, but totally wrong data is being decoded.
CuriousOne Today, 06:07I just tried this code, and it does not work:
TX:
Main:
FOR TxValue = 0 TO 255
Yes, X is word type, and it sometimes get values over 8 bits, but never 345.
I tried sending lower numbers, like 4 or 16 or whatever - they also got distorted.
I also tried like this:

Hello Ioannis,
good question,
when I design the PCB I used the PortB.5 with a 20Mhz crystal with bigger pcb foot print 46x17mm
then I decided to lower the parts count and the PCB foot print...
1. How can you be sure that the receiving PIC will start "listening" just before the sending PIC? Better use a start character on the sender and use this character as a WAIT one on the receiving PIC...
Ioannis Yesterday, 22:13Thanks for posting your project.
But why not use the Hardware USART instead of the Software one?

final code update in "16F690 LCD BACKPACK"
the low rs and high rs lines are not needed, since it control PortA.0 and not the HD44780 chip.
Hello.
Having a strange issue.
PIC18F45K80 and PIC16F1936.
they are connected to each other via 22K resistor. PORTC.3 on both.
Trying to run the simple code:
TX: (1936)

Hello,
jackberg1 Today, 12:01you're right
my assumption was that software or hardware control serial communication are the same
and one way or another I'll get the same result.
if I may ask in this project what...
