GPIO pin

Check the official website of Nanopc-T4, check the interface layout of Nanopc-T4, as shown in Figure 1, the GPIO pin definition corresponds to the actual ARM board, as shown in Figure 1, the first row of GPIO pins from left to right are Pin2, 4 , 6 are in the lower row, and the second row is Pin1, 3, and 5 in the lower row.

Enter gpio readall on the terminal of the ARM board to
view the corresponding relationship between wPi and Physical (GPIO0 pin is ARM pin 11, GPIO7 pin is ARM pin 7), and then perform hardware GPIO connection
