DCC Signal->OPS->Railcom UART selection is ambiguous #44

Closed TrainzLuvr closed 4 years ago

TrainzLuvr commented 4 years ago

When enabling Railcom, an option is presented to select a Railcom UART: UART1 or UART2.

This is rather ambiguous because UART1 is already reserved to provide optional output on pins 5 and 16 via J3, as per the current ESP32CS schematic.

I believe there should not be an option to select UART (or default to UART2), unless UART1 could be shared somehow between Railcom and the UART1 header J3.

This is one downside of the current idf.py menuconfig utility, there is no clear way to declare a set of defaults and target specific overlays. In the CI build I work around this limitation here by adding the extra defaults file, but I have not found a way to automate this via idf.py menuconfig or within VSCode via the extension.
