Use TCP slave without UART #66

Closed alejandroalis closed 1 year ago

Sorry this is a question, not an issue, but don't know where to ask...

One question, I'm trying to use the H743TCP example on a H735 device but only want to use the TCP protocol and It seems that the USART is always enabled, it's possible to use the library without any uart?

Thanks!

I think the library requires some headers and references to USART even when not used. Solving that might require some cleaning of the library. Meanwhile you can add a serial port to your project and simply don't use it.

yes, working without uart because I don't setup it and TCP is working.. I'm trying to understand how the library works because I never used modbus and very confused about the registers (coils, inputs..)
