Pins of the Raspberry Pi Pico W module

The Raspberry Pi Pico W is equipped with 26 GPIO pins. Among them you can find interfaces such as: 2x SPI, 2x I2C, 2x UART, 3x ADC 12-bit, 16x PWM. The module is additionally equipped with 8 programmable IO pins (PIO), which are designed to support non-standard peripheral devices.

Raspberry Pi Pico W power supply

The board has a built-in microUSB port, which is used both for power supply and communication of the Raspberry Pi Pico W board with a computer. For proper operation, the module requires a 5V power supply. The board can also be powered from the VSYS pin with voltage from 1.8 V to 5.5 V , using, for example, a 3.7 V Li-Pol battery or a 3x AA battery.

The logical part of the Raspberry Pi Pico works with a voltage of 3.3 V.

Raspberry Pi Pico W programming

The Raspberry Pi Pico W is programmed in C / C ++ or MicroPython . In order to upload the program to the board, press and hold the BOOTSEL button and connect the Raspberry Pi Pico to the computer with a microUSB cable. The computer will detect the module as a USB mass storage device called RPI-RP2, the program file should be dragged and dropped into the newly found volume. The manufacturer provides an SDK repository for the C / C ++ and MicroPython programming languages, which can be found in the useful links below.

Getting started with MicroPython

Getting started with MicroPython

The Raspberry Pi Pico W is programmed by connecting to a computer with a USB cable by dragging and dropping the program code file to the newly created volume. There is also a sample UF2 file for download to help you get started with MicroPython.

  • Download the MicroPython UF2.
  • Press and hold the BOOTSEL button and plug the board into the USB port of your Raspberry Pi or computer.
  • Release BOOTSEL when Pico is connected to your computer.
  • The Raspberry Pi Pico will be detected as a mass storage device with volume RPI-RP2.
  • Drag and drop the MicroPython UF2 file to the RPI-RP2 volume.
  • Pico will restart, MicroPython will now be used.
  • You can access REPL and MicroPython via the serial USB port.

Download the UF2 .

Hello World in C / C ++

The first program any programmer will write is "Hello World", in this case the Raspberry Pi Pico W will be programmed via the Raspberry Pi 4B 's USB serial port.

  • Download the UF2 file "Hello World".
  • Press and hold the BOOTSEL button and connect the Raspberry Pi Pico to the Raspberry Pi's USB port.
  • The board is detected as a mass storage device with volume RPI-RP2.
  • Drag and drop the UF2 file to the RPI-RP2 volume.
  • Pico will restart.
  • Open a terminal on the Raspberry Pi 4B and run the commands:
     sudo apt install minicom
    minicom -b 115200 -o -D / dev / ttyACM0
    
  • You should see "Hello World" listed in the terminal window.

Question: I have a question if bluetooth communication is also possible or do you have to somehow change the configuration of CYW43439 ?
Answer: Unfortunately, the manufacturer does not provide any information regarding the possibility of using bluetooth.
It is possible that this functionality will appear but is not available at this time.

Anyone who wants to integrate sensors and actuators via WLAN or BLE with minimal effort is very well served. With MicroPython, for example, you can create MQTT clients with just a few lines, which can then be integrated into your own home automation. Limitless possibilities.

Ok ok ok
Dariusz 27.01.2023 Confirmed purchase Translated review
Cheaper than Arduino Uno and much more powerful (including 32 bits and 2 cores). For this price, I am surprised by the capabilities of this processor, because it can be programmed in C ++ 17. The downside is that it does not have a built-in button to stop the processor so that it can be easily switched to program loading mode, but it can be added next to it without additional elements (on the web you can find examples).
Allan 16.01.2023 Confirmed purchase Translated review
It's hard to overestimate a great module. A bug in the Pico SDK (connection error to an unsecured WiFi network) is a bit of a concern. In a set with other WiFi modules (e.g. ESP32-CAM) it allows you to easily create a local IoT network system.
