Programmatically switching console between USB and UART? #19665
|
Is there a way to programmatically switch console between USB and UART (pins 1 & 2)? I have a project/script which is really stressing the CPU and is time critical; I am seeing that USB traffic is being delayed and I think that the console is playing it's part in this.... I can build a UF2 with the console compiled to being on UART, but then that's a bit more work for my users. Hoping there is a way to switch operation, so that it's only on the UART when the project is in particular modes (ie. connected to send Midi Timecode via USB). |

I'm pretty sure at the moment only the stm32 port has support for dynamically switching on/off the built-in repl channels (uart/usb-cdc) via os.dupterm, in the other ports it can only be changed at compile time. |

Thanks, guess I'll have to work around by detecting when I want to manually switch printing on/off |
