Absolutely Warday.
However he is setting the option USE_WITH_PC, and this overrides the
settings to force it to use INT_EXT, and a software UART.
_Why_ he is using this option, I have not really worked out,
This option is not wanted for most configurations. It is designed for
using the standard CCS demo where you want to connect the chip's
UART to a PC, and have this then talking to the RS485. |

Indeed. That's why I suggest replacing the demos initialization with your own as I show in the fix. (Delete the use with pc and use only what I needed). I saw different topics with this problem but with no solution (They fix it and then they do not reply with the fix). That’s why I post the solutions that I found. If someone have the same problem, he may know where to start. Thanks for all the comments. See you soon!
I will let this here to close the topic.

Absolutely.
I think he has persuaded himself, that because he is connecting to a
PC, he needs this setting. Wrong. This setting is only for a very specific
'demo' environment, where you have the PC connected to the PIC's
UART, to allow it to monitor the modbus being handled by the PIC.
If you are connecting a PC that is itself acting as a modbus master or
slave, you do not want this setting. |
