[Arduino IDE demo source code for KC868-A6]--#09-RS485_code

[Alpha]

do you have define the Serial2 pin in your arduino config fle firstly?

this is RS485 pin define for KC868-A6

Ah!  Ok.  I made that change and my Modbus read is now working!  Excellent, thankyou very much.

Did I miss some documentation / wiki that tells me to change the RX2 and TX2 pins?  Is there other defines that I should be changing?

Thanks again, I'm really enjoying working with this board.  It's a really nice layout.

Cheers,

alex
