Please note that: On OrangePi 2G-IOTIoT, GPIOA, GPIOB and GPIOD tract as general GPIO, but GPIOC as non-general GPIO. Because of some hardware design. The host of GPIOC is modem not CPU. So, If CPU wanna control GPIOC, it must send message to Modem, and Moden get message and control GPIOC, it's not good news. In other words. on version 0.1, GPIOC only support "OUTPUT" mode. <br>
The size of GPIOx group is 32, so we can get gpio map:<br>
GPIOA: 0   -  31<br>
