I'm a beginner to C and i want to learn it cause it has much more libraries than micropython and has more functions that i will need in my project.
I wanted to set CPU (RP2040) clock to 133khz using set_sys_clock_khz(133, false) function, but it gives me error:
Board that im using is pico w
I'm using Raspberry Pi Pico extension to compile it and flash with swd
C-Flipberry.c code:printu() is function written by me that work like prinf but to PIO uart cause uart pins on pcb that i made are alredy used and i need USB
