BuildSetSamplingIntervalRequest(System.Int32) Generates a byte array containing the encoded data that represents a request to set the sampling rate for the Firmata sketch running on the target hardware. The sampling rate is how frequently the target hardware polls for data updates.
BuildSystemResetRequest() Generates a byte array containing the encoded data that represents a request to reset the stored state on the target device. This does not request a hard reset of the target hardware.
