SKR 1.4 turbo Serial RX/TX Wifi

[VeXed2]

Hello, I am trying to use this to use the board with Wifi instead of USB. I've commented "#define USB_SERIAL_CDC" in my_machine.h, I've put these:

• {4, 28, IOCON_MODE_INACT | IOCON_FUNC1}, / TXD3 /
• {4, 29, IOCON_MODE_INACT | IOCON_FUNC1} / RXD3 /

• define SERIAL_IRQHandler UART3_IRQHandler

• define SERIAL_MODULE LPC_UART3

• define SERIAL_MODULE_INT UART3_IRQn

  but I can't manage to connect through serial, the web page for esp works, I've set it to GRBL but can't manage to get data from it. Anyone knows how I can make this work?

Try with IOCON_FUNC3 instead of IOCON_FUNC1 for the pin mapping. Ref table 86 in the user manual (UM10360).

That fixed it. Thank you very much :)
