Our examples at: rpi-pico-w/upython.
The examples can be run as described at Program Raspberry Pi Pico W with MicroPython.
- rpi-pico-w/upython/blink.py: blink on-board LED. Note that they broke the LED hello world compatibility from non-W to W for God's sake!!!
- rpi-pico-w/upython/led_on.py: turn on-board LED on and leave it on forever
- rpi-pico-w/upython/uart.py: has automatic UART via USB. Any
print()command ends up on the Raspberry Pi Pico W UART! Is is just like with Micro Bit, must be a standard Micro Python thing. The onboard LED is blinked as a heartbeat. - rpi-pico-w/upython/blink_gpio.py: toggle GPIO pin 0 on and off twice a second. Also toggle the on-board LED and print to UART for correlation. You can see this in action e.g. by linking an LED between pin 0 and one of the GND pins of the Pi, and the LED will blink.
- rpi-pico-w/upython/pwm.py: pulse width modulation. Using the same circuit as the rpi-pico-w/upython/blink_gpio.py example, you will now see the external LED go from dark to bright continuously and then back
- rpi-pico-w/upython/adc.py: analog-to-digital converter. The program prints to the UART the value of the ADC on GPIO 26 once every 0.2 seconds. The onboard LED is blinked as a heartbeat. The hello world is with a potentiometer: extremes on GND and VCC pins of the Pi, and middle output on pin 26, then as you turn the knob, the uart value goes from about 0 to about 64k.
