SAMPLE (4, 04h)

The SAMPLE command provides a single snapshot of the data sampled from one port or all ports, whether configured for an analog sensor or a digital (I2C) sensor. Upon completion of the command the USB-microDig sends out the SAMPLE DATA message, whether in host or stand-alone mode.

The [BODY] of the SAMPLE command is composed of one byte - the sensor input number:

0000xyyy: x = 1; apply the command to all ports (yyy is ignored), ie. send 8 messages with the sensor data for each port
yyy = [0..7]; ports, where the first port number = 0, and the last (8th) port number = 7

Example:

In order to sample port 5, the following message is sent:

240, 125, 0 {DEV}, 4 {SAMPLE}, 4 {yyy}, 247 (F0h, 7Dh, 00h, 04h, 04h, F7h)
