Standard GPIO testing

Interface property

Interface position : P21
1）GPIO output test
The test of standard GPIO takes P21:35 and P21:36 as examples. Other GPIO tests can refer to this test method.

Configure P21:35 for output
Enter the following command:

# OUT_IO_OUT_NUM=4 
# echo ${OUT_IO_OUT_NUM} > /sys/class/gpio/export    
# echo "out" > /sys/class/gpio/gpio${OUT_IO_OUT_NUM}/direction  
# echo 0 > /sys/class/gpio/gpio${OUT_IO_OUT_NUM}/value

Note: configure P21:35 to output low level and measure by multimeter. If pin P21:35 voltage is 0V, configure OK.

Configure P21:36 for output
Enter the following command:

# OUT_IO_OUT_NUM=3  
# echo ${OUT_IO_OUT_NUM} > /sys/class/gpio/export
# echo "out" > /sys/class/gpio/gpio${OUT_IO_OUT_NUM}/direction  
# echo 1 > /sys/class/gpio/gpio${OUT_IO_OUT_NUM}/value

Note: configure P21:36 to output low level and measure by multimeter. If pin P21:35 voltage is 3.3V, configure OK.

2）Control the output level
Enter the following command:

# echo 0 > /sys/class/gpio/gpio${OUT_IO_OUT_NUM}/value   
# echo 1 > /sys/class/gpio/gpio${OUT_IO_OUT_NUM}/value

Control output level can be achieved.

Other available GPIO: P21:33,34,23;The corresponding IO serial Number is: 2,1,110

GPIO-LED test

led-heartbeat

led-heartbeat Connect to the indicator D12, and you can see the D12 flashing regularly after the system starts.

led-timer

led-timer Connect to the indicator D8, and you can see the D8 flashing regularly after the system starts.
Control high&low electrical time
