Using gpio readall, you can see the value of No. 7 pin (V) into 1
5) The setting method of other pins is similar, just modify the serial number of wPi to the
corresponding serial number of the pin
3.16.2. 40pin GPIO port pull-down resistance setting method
Note that the 4 GPIO pins below Orange Pi 3B are invalid because there are
3.3V on the outside, so setting drop-down is invalid. Other pins can be set normally
1) Below the No. 11 pin — corresponding to GPIO 3_C6-corresponding wPi serial
number 5—to demonstrate how to pull-down resistance of the GPIO port
