There is an explosion of DIY electronics projects, largely fueled by Arduino-based microcontrollers and Raspberry Pi computers. Electronics projects have never been easier to build, with hundreds of inexpensive modular components to choose from. People design robots, home monitoring and security systems, game devices, musical instruments, audio systems, and lots more. The Raspberry Pi Pico is the Raspberry Pi Foundation’s entry into the Arduino-style microcontroller market. A regular Raspberry Pi computer runs Linux and typically costs from $35 to $100 depending on memory and accessories. The Raspberry Pi Pico costs $4 and doesn’t run an operating system. To power the Raspberry Pi Pico, the Raspberry Pi Foundation designed a custom System on a Chip (SoC), called the RP2040, containing dual ARM Cortex-M0+ CPUs along with a raft of device controller components. This combination of a powerful CPU and ease of integration has made this a great choice for any DIY project. Further, Raspberry sells the RP2040 chips separately, and other companies such as Seeed Studio, Adafruit, and Pimoroni are selling their own versions of this microcontroller with extra built-in features like Bluetooth or Wi- Fi. The RP2040 chips can even be purchased for approximately $1 each to build your own board. At the basic level, how are these microcontrollers programmed? What provides the magical foundation for all the great projects that programmers build with them? Raspberry provides a Software Developer’s Kit (SDK) for C programmers as well as support for programming in MicroPython. This book answers these questions and delves into how these are programmed at the bare metal level and provides insight into the RP2040’s architecture. Assembly Language is the native, lowest-level way to program a computer. Each processing chip has its own Assembly Language. This book covers programming the ARM Cortex-M0+ 32-bit Processor. To learn how a computer works, learning Assembly Language is a great way to get into the nitty-gritty details. The popularity and low cost of microcontrollers like the Raspberry Pi Pico provide ideal platforms to learn advanced concepts in computing. Even though all these devices are low-powered and compact, they’re still sophisticated computers with a multi-core processor, programmable I/O processors, and integrated hardware controllers. Anything learned about these devices is directly relevant to any gadget with an ARM processor that by volume is the number one processor on the market today. In this book, how to program ARM Cortex-M0+ processors at the lowest level, operating as close to the hardware as possible, is covered. How to do the following will be learned: -Format instructions and combine them into programs, as well as the formats of operative binary data. -Program the built-in programmable I/O, division, and interpolation coprocessors. -Control the integrated hardware devices by reading and writing to the hardware control registers directly. -Interact with the RP2040 SDK. The simplest way to learn these tasks is with a Raspberry Pi Pico connected to a Raspberry Pi running the Raspberry Pi OS, a version of Linux. This provides all the tools needed to learn Assembly Language programming. All the software required for this book is open source and readily available on the Raspberry Pi. This book contains many working programs to play with, use as a starting point, or study. The only way to learn programming is by doing, so don’t be afraid to experiment as it is the only way to learn. Even if Assembly programming isn’t used in day-to-day life, knowing how the processor works at the Assembly Language level and the low-level binary data structures will make for better programming in all other areas. Knowing how the processor works will translate to writing more ef
