pwm method

Future<bool> pwm(int pwmOutput)

Assigns the analog (PWM) output value. (BITalino 2 only) Returns true if the command is sent successfully, false otherwise.

Throws BITalinoException(BITalinoErrorType.NOT_IMPLEMENTED_IOS) if this method is called on IOS devices. Throws BITalinoException(BITalinoErrorType.NOT_BITALINO2) if the device is not BITalino2. Throws BITalinoException(BITalinoErrorType.TIMEOUT) if the timeout limit is reached. Throws BITalinoException(BITalinoErrorType.BT_DEVICE_NOT_CONNECTED) if a device is not connected. Throws BITalinoException(BITalinoErrorType.BT_DEVICE_CANNOT_BE_RECORDING) if the device is recording. Throws BITalinoException(BITalinoErrorType.CUSTOM) if a native exception was raised.
