RP2040 assembly language programming : ARM Cortex M0+ on the Raspberry Pi Pico Learn to program the Raspberry Pi Pico’s dual ARM Cortex M0+ CPUs in Assembly Language. The Pico contains a customer System on a Chip (SoC) called the RP2040 making it the Foundation’s first entry into the low cost microcontroller market. The RP2040 contains a wealth of coprocessors for performing arithmetic as well as performing specialized I O functionality. This book will show you how these CPUs work from a low level easy to learn perspective. There are eight new Programmable I O (PIO) coprocessors that have their own specialized Assembly Language supporting a wide variety of interface protocols. Youll explore these protocols and write programs or functions in Assembly Language and interface to all the various bundled hardware interfaces. Then go beyond working on your own board and projects to contribute to the official RP2040 SDK. Finally youll take your DIY hardware projects to the next level of performance and functionality with more advanced programming skills. You will: Read and understand the Assembly Language code that is part of the Pico’s SDK Integrate Assembly Language and C code together into one program Interface to available options for DIY electronics and IoT projects.
