Thus for the CM4 you should not use the RCMPin pin provider, 043 * but rather use the traditional 'RaspiPin' pin provider just like you would for a RPi 4B. 044 * 045 * @author Robert Savage (<a 046 * href="http://www.savagehomeautomation.com">http://www.savagehomeautomation.com</a>) 047 * 048 * For PWM pin definitions see: http://elinux.org/RPi_BCM2835_GPIOs 049 */ 050@SuppressWarnings("unused") 051public class RCMPin extends PinProvider { 052 053 public static final Pin GPIO_00 = createDigitalPin(0, "GPIO 0");
