Hi! I am sorry to disturb you, I know clockworkpi in gameshell has 14 pins can be used as communication pin to connect with other devices with UART/SPI/I2C, but I don’t know how to control gpio in software. I have seen this page but It seems people in the page has no idea to control it in /sys/class/gpio. And then I seen this page, it’s a video to teach how to control gpio in orange pi, but the orange pi has larger difference with clockworkpi. Do you get some experience in clockworkpi gpio control? Can you help me？
