Hi all,

I want a modbus example of ex_modbus_master.c and ex_modbus_slave.c files with schematic

[tesla80]

any help?

I didn't hear a real question. The configuration should basically work, I think.

In addition, you should have:
- resistors at the RS-485 bus to set the idle state
- pull-up resistors at the processor Rx pins (can be possibly an internal pullup as well) to force idle state when Tx is enabled.
