Test Command
GPIO Expander
JP5.1.0
Test GPIO high/low
- GPIO0 (228) : gpio-419 (PN.01)
- GPIO1 (118) : gpio-440 (PQ.05)
- GPIO2 (127) : gpio-318 (PCC.01)
- GPIO3 (206) : gpio-443 (PR.00)
- GPIO4 (208) : gpio-437 (PQ.02)
- GPIO5 (211) : gpio-453 (PS.04)
- GPIO6 (212) : gpio-436 (PQ.01)
- GPIO7 (218) : gpio-321 (PCC.04)
1).Switch to root
ubuntu@localhost:~ sudo -s
2).Commnad : where <GPIO> : gpio number and <LEVEL> : high(1)/low(0)
For example, pull up GPIO0 to high.
root@localhost:/home/ubuntu# echo 419 > /sys/class/gpio/export root@localhost:/home/ubuntu# echo out > /sys/class/gpio/PN.01/direction root@localhost:/home/ubuntu# echo 1 > /sys/class/gpio/PN.01/value
