Hello everyone,
I am trying to implement

 Modbus communication with LAUNCHXL2-57LC43 and Venus-Gx.

The platform for this developing is Code Composer Studio IDE.

I want to get all information received by the Venus-GX from SmartSolar Charge Controller to my Launch Pad  TMS570LC43x.

What I have tried:

I have ready code for intializing web server and get the device ip address. 

But I don't know how to read data from Venus GX.

Guys, please make it quick. I have to submit it by this week.

Hopefully, 
Advaith

You should study the MODBUS specifications (they are simple and freely available online), and the documentation provided by the device manufacture (a starting point could be this page: GX Modbus-TCP Manual [Victron Energy][^]).
