FAQ

Arduino

1. Code upload failed in Arduino IDE?

   • Check that your Pico is correctly recognised by the Arduino IDE, the port should be COMXX (Raspberry Pi Pico 2), for instructions please refer to 1.3 Setting Up the Raspberry Pi Pico 2 (Important).

   • Check that the Board(Raspberry Pi Pico 2) or port（COMXX (Raspberry Pi Pico 2)）is selected correctly.

   • If your code is OK and you have selected the correct board and port, but the upload is still not successful. At this point you can click on the Upload icon again, when the progress below shows “Upload…”, unplug the USB cable, then press and hold the BOOTSEL button to plug it in and the code will be uploaded successfully.

MicroPython

1. How to open and run the code?

   For detailed tutorials, please refer to Open and Run Code Directly.

2. How to upload library to Raspberry Pi Pico 2？

   For detailed tutorials, please refer to Upload the Libraries to Pico.

3. NO MicroPython(Raspberry Pi Pico) Interpreter Option on Thonny IDE?

   • Check that your Pico is plugged into your computer via a USB cable.

   • Check that you have installed MicroPython for Pico (1.3 Install MicroPython on Your Pico2).

   • The Raspberry Pi Pico 2 interpreter is only available in version 3.3.3 or higher version of Thonny. If you are running an older version, please update (1.2 Install and Introduce Thonny IDE).

   • Plug in/out the micro USB cable sveral times.

4. Cannot open Pico code or save code to Pico via Thonny IDE?

   • Check that your Pico is plugged into your computer via a USB cable.

   • Check that you have selected the Interpreter as MicroPython (Raspberry Pi Pico).COMxx.

5. Can Raspberry Pi Pico 2 be used on Thonny and Arduino at the same time?

   NO, you need to do some different operations.

   • If you used it on Arduino first, and now you want to use it on Thonny IDE, you need to 1.3 Install MicroPython on Your Pico2 on it.

   • If you used it on Thonny first， and now you want to use it on Arduino IDE, you need to 1.3 Setting Up the Raspberry Pi Pico 2 (Important).

6. If your computer is win7 and pico cannot be detected.

   • Download the USB CDC driver from http://aem-origin.microchip.com/en-us/mindi-sw-library?swsearch=Atmel%2520USB%2520CDC%2520Virtual%2520COM%2520Driver

   • Unzip the amtel_devices_cdc.inf file to a folder named pico-serial.

   • Change the name of amtel_devices_cdc.inf file to pico-serial.inf.

   • Open/edit the pico-serial.inf in a basic editor like notepad

   • Remove and replace the lines under the following headings:

   [DeviceList]
   %PI_CDC_PICO%=DriverInstall, USB\VID_2E8A&PID_0005&MI_00
   
   [DeviceList.NTAMD64]
   %PI_CDC_PICO%=DriverInstall, USB\VID_2E8A&PID_0005&MI_00
   
   [DeviceList.NTIA64]
   %PI_CDC_PICO%=DriverInstall, USB\VID_2E8A&PID_0005&MI_00
   
   [DeviceList.NT]
   %PI_CDC_PICO%=DriverInstall, USB\VID_2E8A&PID_0005&MI_00
   
   [Strings]
   Manufacturer = "ATMEL, Inc."
   PI_CDC_PICO = "Pi Pico Serial Port"
   Serial.SvcDesc = "Pi Pico Serial Driver"
   

   1. Close and save and make sure your retain the name as pico-serial.inf

   2. Go to your pc device list, find the pico under Ports, named something like CDC Device. A yellow exclamation mark indicates it.

   3. Right click on the CDC Device and update or install driver choosing the file you created from the location you saved it at.
