Introduction to bare metal programming -
Join David as he investigates Bare Metal Programming for a Raspberry Pi Pico. After an overview of the RP2040 processor architecture, we’ll do an introduction into ARM assembly language. Finally we’ll write our first bare metal ARM assembly language program. See the next video, Bare Metal Adventures, Chapter 2 on compiling, linking, and loading the program into the Pico.
