Hi,
I've moved a larger project from Arduino IDE , where I have debug printing to Wire Serial1 on gp4 and gp5, to sdk.
Using SDK I'm having trouble getting UART1 on pins 4,5 so I thought I'd take the hello_serial example and test that.
https://github.com/raspberrypi/pico-exa ... o_serial.c
The supplied CMakeLists.txt seemed short of what was needed even to get this trivial example to compile. I added a few lines from what I'd learnt bulding the main project. I now have this:
I have gp4,5 wired to a FTDI device. This was previously seen to work using the IDE. Listening to this port I get nothing. It's probably something stupid I'm over looking. Any suggestion?
TIA.
