RASPBERRY PI PICO W - DOGAN IBRAHIM KARTONIERT ...

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 on-board Infineon CYW43439 Bluetooth and Wi-Fi chipset. At the time of writing this
book  the 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 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 Digital-to-analogue converter (DAC) projects All
projects are tried & tested. They can be implemented on both the Raspberry Pi Pico and
Raspberry Pi Pico W  although the Wi-Fi-based subjects will run on the Pico W only. Basic
programming and electronics experience are required to follow the projects. Brief descriptions
block diagrams  detailed circuit diagrams  and full MicroPython program listings are given for
all projects. The full program listings of all the projects discussed in the book may be
downloaded free of charge from www.elektor.com 20335.
