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. You'll 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, you'll take
your DIY hardware projects to the next level of performance and
functionality with more advanced programming skills.
What You'll Learn
-
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
**Who This Book Is For
**Makers who have already worked with microcontrollers, such as the
Arduino or Pico, programming in C or Python. Those interested in going
deeper and learning how these devices work at a lower level, by learning
Assembly Language.
