Hardware Connection

Please take care of the direction when you connect Pico, a USB port is printed to indicate. You can also check the pin of Pico and the module when connecting.

Demo Download

1. Directly download it on the Raspberry Pi: Open the Raspberry Pi and execute:

sudo apt-get install p7zip-full
cd ~
sudo wget  https://files.waveshare.com/upload/8/8a/Pico-CAN-B-Code.7z
7z Pico_Pico-CAN-B-Code.7z -o./Pico-CAN-B-Code.7z
cd ~/Pico-CAN-B-Code

2. Also, you can download the demo in the #Resource.

How to Use the Demo

Python

• 1. Press and hold the BOOTSET button on the Pico board, connect the pico to the USB interface of the computer through the Micro USB cable, and release the button after the computer recognizes a removable hard disk (RPI-RP2).
  
• 2. Copy the pico_micropython_xxxxx.uf2 file in the python directory to the recognized removable disk (RPI-RP2).
  
  • Download the official firmware.
• 3. Open Thonny IDE (Note: Please use the latest version of Thonny, otherwise there is no Pico support package, the latest version in Windows is v3.3.3).
  
• 4. Click Tools -> Settings -> Interpreter, and select Pico and the corresponding port as shown in the figure.
  

• 5. File -> Open -> MCP2512.py file, click to run, as shown in the following figure:

This is a transceiver demo, connect to another CAN device (A-A B-B connection), configure the frame ID 0x123, and then send 1-8 in turn.

Arduino IDE Series

Install Arduino IDE

1. Download the Arduino IDE installation package from Arduino website.
   
2. Just click on "JUST DOWNLOAD".
   
3. Click to install after downloading.
   
4. Note: You will be prompted to install the driver during the installation process, we can click Install.
   

Install Arduino-Pico Core on Arduino IDE

1. Open Arduino IDE, click the File on the left corner and choose "Preferences".
   
2. Add the following link in the additional development board manager URL, then click OK.
   

   https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json

   
   Note: If you already have the ESP8266 board URL, you can separate the URLs with commas like this:

   https://dl.espressif.com/dl/package_esp32_index.json,https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
   

3. Click on Tools -> Dev Board -> Dev Board Manager -> Search for pico, it shows installed since my computer has already installed it.
   
   

Upload Demo At the First Time

1. Press and hold the BOOTSET button on the Pico board, connect the Pico to the USB port of the computer via the Micro USB cable, and release the button when the computer recognizes a removable hard drive (RPI-RP2).
   
   
2. Download the demo, open arduino\PWM\D1-LED path under the D1-LED.ino.
3. Click Tools -> Port, remember the existing COM, do not need to click this COM (different computers show different COM, remember the existing COM on your computer).
   
4. Connect the driver board to the computer with a USB cable, then click Tools -> Ports, select uf2 Board for the first connection, and after the upload is complete, connecting again will result in an additional COM port.
   
5. Click Tool -> Dev Board -> Raspberry Pi Pico/RP2040 -> Raspberry Pi Pico.
   
6. After setting, click the right arrow to upload.
   
   • If you encounter problems during the period, you need to reinstall or replace the Arduino IDE version, uninstall the Arduino IDE needs to be uninstalled cleanly, after uninstalling the software you need to manually delete all the contents of the folder C:\Users\[name]\AppData\Local\Arduino15 (you need to show the hidden files in order to see it) and then reinstall.
