Serial communication RS-485 between Pic16F690/PIC16F18877

[ciclingman]

Good morning Susan. Last weekend I solved my communication problem, discovering that there were 2 settings to do that I didn't read in the datasheet and that you didn't recommend:

The first approach is this:
RC6PPS = 0x10;

The second setting is the setting of the communication pines as entrances.
I was wrong because I set the TX as output, RX as input exactly as I did with the PIC16F690. The rest of the program is always the same.
