Hello,
I connected RX0 and RX1 to a microcontroller PIC18.
I have two counters on the screen, see picture attached, sometimes I got increment of 256 instead of 1,2,3....
I tried lower the baud rate but it is not solving the problem.
It looks like pwr on/off some times help.
The Micro PIC18 CODE for both uart:
" (all Long types)
byte1 = Temp_value_12 >> 8 ;
byte2 = Temp_value_12 & 0x00FF;
// unsigned char result = ( ( byte1 - '0' ) << 4 ) | ( byte2 - '0' );
putc(byte1, uart2);
putc(byte2, uart2);
"
PICASO CODE:

#inherit "NegDigitsConst.inc"
