GPIOを使う

GPIO25の場合、以下ではエラーになる

$ echo 25 > /sys/class/gpio/export
-bash: echo: write error: Invalid argument

なので以下を実行

$ cat /sys/kernel/debug/gpio | grep GPIO25
 gpio-537 (GPIO25              )
$ echo 537 > /sys/class/gpio/export
$ cat /sys/kernel/debug/gpio | grep GPIO25
 gpio-537 (GPIO25              |sysfs               ) out lo
$ echo 1 > /sys/class/gpio/gpio537/value
$ cat /sys/kernel/debug/gpio | grep GPIO25
 gpio-537 (GPIO25              |sysfs               ) out hi
$ echo 0 > /sys/class/gpio/gpio537/value
$ cat /sys/kernel/debug/gpio | grep GPIO25
 gpio-537 (GPIO25              |sysfs               ) out lo
$ echo 537 > /sys/class/gpio/unexport
$ cat /sys/kernel/debug/gpio | grep GPIO25
 gpio-537 (GPIO25              )
