1. Step to install boot Firmware

• Every Rotary Pico W board will be provided with boot firmware already installed, so you can skip this step and directly go to step 2.
• If in case you want to install firmware for your board, Push and hold the BOOTSEL button and plug your Pico W into the USB port of your computer. Release the BOOTSEL button after your Pico is connected.

• It will mount as a Mass Storage Device called RPI-RP2.
• Drag and drop the MicroPython UF2 - Rotary Pico W_firmware file provided in this github onto the RPI-RP2 volume. Your Pico will reboot. You are now running MicroPython.

2. Onboard LED Blink

• Download Thonny IDE from Download link as per your OS and install it.

• Once done start Thonny IDE application, Connect ReadPi to laptop/PC.

• Select the device at the bottom right with a suitable COM port, as shown in the below figure. You might get a different COM port.

  

• Write simple onboard blink Python code or Download Led blink code, then click on the green run button to make your script run on Rotary Pico W.

  

  Now that we've reached this point, you're executing your script through Thonny IDE, so if you unplug Pico, it will stop running. To run your script without using an IDE, simply power up Rotary Pico W and it should run your script, go to step 3. Once you have transferred your code to the Rotary Pico W board, to see your script running, just plug in power either way using micro USB or via Vin, both will work.

3. How to move your script on Pico W of Rotary Encoder

• Click on File -> Save Copy -> select Raspberry Pi Pico W, Then save file as main.py

  

  Similarly, you can add various Python code files to Pico. Also, you can try out sample codes given here in examples folder.

• But in case you want to move multiple files at one go, for example, suppose you are interested in saving the library files folder into Pico W, the below image demonstrates that

  

NOTE: Don't rename lib files or other files, only your main code script should be renamed as main.py for standalone execution without Thonny.

Example Codes

Save whatever example code file you want to try as main.py in Pico W as shown above step 3, also add related lib files with the default name. In example folder you will find demo example script code to test onboard components of Rotary Pico W like

• Library: before running the code kindly save this library inside Pico W.
• Display test, RGB test, SD Card test, and touch test, etc.: All demo file
• Image display test: testing image display.
