Hardware flow control #19

Open wdevore opened 1 year ago

wdevore commented 1 year ago

Curious, Is the lack of CTS/RTS a result of pico limitations or PIO?

If you look at the code, it actually contains uart_set_hw_flow(ui->inst, false, false); which explicitly disables RTS/CTS hardware flow control. See the pico-sdk documentation at https://www.raspberrypi.com/documentation/pico-sdk/hardware.html#ga54a9e298ebec96510e324bbab01247c7

So there's no limitation aside from software, AFAICT
