Arduino

RPi pico

This demo is using RPI pico. For using RPI pico in arduino, please check https://github.com/earlephilhower/arduino-pico

Other Arduino board

You can use other Arduino board which should work in similar way. Just check the pin assignment of PIO, AIN and UART port should match with the code assignment.

arduino-timer

The arduino-timer library can be found in https://www.arduino.cc/reference/en/libraries/arduino-timer/, download the ZIP library.

To install library: arduino-IDE->Sketch->Include Library->Add ZIP library.

Demo code

The directory [arduino_pico] contain the demo code of RPI pico.

Hardware

This schmatic diagram of this demo is showing as following. The pico linked with BunHMI by UART interface.

Server motor is controlled by PWM and VR is the simulation of Analog input.
