USB-CAN-A
- GND is connected to pin 38 of the Raspberry Pi Pico W.
- CAN_L is connected to pin 6 of the Raspberry Pi Pico W.
- CAN_H is connected to pin 7 of the Raspberry Pi Pico W.
Embedded Code
Raspberry Pi Pico W Code
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
This code is a basic template for the Raspberry Pi Pico W. The setup function is intended for initialization code that runs once, while the loop function contains the main code that runs repeatedly.
