EK-TM4C123GXL: How to implement Modbus-RTU-485 protocol with TM4C123 board

Rashmi Dingre

Part Number: EK-TM4C123GXL

Hello All,

I want to implement Modbus-485-RTU protocol with TM4C123 board using CCS.6, Where can I get library(Modbus API) that can support TM4C123 board, and a sample code to begin with.

Thanks,

Rashmi

You don't reveal, "Where you've already looked" do you? As a result - don't your "helpers" risk, "Re-tracing your (failed) steps?" Can that be fair/proper?

There are so many "special" requirements - you seem to believe that a "modbus API" exists - how have you come to that conclusion?

Your providing (some) reporting of the "focused" efforts you've expended will best enable your support...
