Make it easier to configure default baud rate #1648

Closed peterharperuk closed 2 weeks ago

peterharperuk commented 4 months ago

To make stdio logging quicker it's probably a good idea to set the default uart speed 921600, but it's only configurable by adding this define to your project. Make it configurable from the cmake command line.

should probably add a PICO_CMAKE_CONFIG so it appears in the docs (or ought to!)

PICO_DEFAULT_UART_BAUD_RATE does already appear on page 482 of https://datasheets.raspberrypi.com/pico/raspberry-pi-pico-c-sdk.pdf if that's what you were referring to? Or am I confusing "Appendix B: SDK configuration" with "Appendix C: CMake build configuration" ?

I think you can only set PICO_DEFAULT_UART_BAUD_RATE if you add it to your CMake file. I was suggesting you can set it by adding PICO_DEFAULT_UART_BAUD_RATE=xyz to the CMake command line

I've added PICO_CMAKE_CONFIG to the CMakeLists.txt file. As @lurch points out - it's already in the header file
