Raspberry Pi Pico W: Program, build, and master 60+ projects with the Wireless RP2040 (1 ed)

Raspberry Pi Pico W: Program, build, and master 60+ projects with the Wireless RP2040 1st ed. Edition

The Raspberry Pi Pico and Pico W are based on the fast, efficient, and low-cost dual-core ARM Cortex M0+ RP2040 microcontroller chip running at up to 133 MHz and sporting 264 KB of SRAM and 2 MB of Flash memory. Besides spacious memory, the Pico and Pico W offer many GPIO pins and popular peripheral interface modules like ADC, SPI, I²C, UART, PWM, timing modules, a hardware debug interface, and an internal temperature sensor.

The Raspberry Pi Pico W additionally includes an onboard Infineon CYW43439 Bluetooth and Wi-Fi chipset. At the time of writing this book, Bluetooth firmware was not yet available. Wi-Fi is however fully supported at 2.4 GHz using the 802.11b/g/n protocols.

This book is an introduction to using the Raspberry Pi Pico W in conjunction with the MicroPython programming language. The Thonny development environment (IDE) is used in all of the 60+ working and tested projects, covering the following topics:

• Installing the MicroPython on a Raspberry Pi Pico using a Raspberry Pi or a PC
• Timer interrupts and external interrupts
• Analogue-to-digital converter (ADC) projects
• Using the internal temperature sensor and external sensor chips
• Using the internal temperature sensor and external temperature sensor chips
• Datalogging projects
• PWM, UART, I²C, and SPI projects
• Using Bluetooth, WiFi, and apps to communicate with smartphones
