Device reply a packet without “Data” field (“Size” is 0, none “Data”)
means fail. If the request performed successfully, device will reply a
packet with specific data structure.
The format is listed below:
GpioPinCfg Structure
Field Type Description
Pin Index byte Pin Index
0x00 – 1st pin index
0x01 – 2nd pin index
……
0xFF – All of the pins
Pin Config Array of
byte
Pin Configuration
0x00 – as a digital input pin
0x01 – as a digital output pin
Host can set configurations of all GPIO pins by sending a request packet
with designating the field “Pin Index” in “GpioPinCfg” as 0xFF.
Device will reply a packet with all GPIO pins configurations in sequential
bytes array. The “Pin Config[]” bytes array are in order of the GPIO pin
index.
