Validate that pin supports specific functionality


validatePin(arduinoObj, pin, type)



validatePin(arduinoObj, pin, type) validates specific functionality on the pin and throws an error if not supported.

Check if pin D12 supports SPI functionality on the Arduino® Uno hardware.

arduinoObj = obj.Parent;

Only pins A4 and A5 support I2C type, the function returns an error for unsupported pins

arduinoObj = obj.Parent;
