說(shuō)明:　

ｇｐｉｏ的ＭＡＰ關(guān)系　yk0--pioA7? yk1--pioA5 ? yk2--pioA9 ? yk3--pioA3 ? yk4--pioA1? yk5--pioA8 ?? (端子從左－－＞右　QD--pioA21內(nèi)部總啟動(dòng)信號(hào)）

1 配置gpio:

root@sama5d3-linux:~ echo 8 > /sys/class/gpio/export?????????????????????????? ?
root@sama5d3-linux:~ echo 1 > /sys/class/gpio/export?????????????????????????? ?
root@sama5d3-linux:~ echo 3 > /sys/class/gpio/export?????????????????????????? ?
root@sama5d3-linux:~ echo 9 > /sys/class/gpio/export?????????????????????????? ?
root@sama5d3-linux:~ echo 5 > /sys/class/gpio/export?????????????????????????? ?
root@sama5d3-linux:~ echo 7 > /sys/class/gpio/export

２ 配置ＧＰＩＯ方向:

root@sama5d3-linux:~ echo out > /sys/class/gpio/pioA8/direction??????????????? ?
root@sama5d3-linux:~ echo out > /sys/class/gpio/pioA1/direction??????????????? ?
root@sama5d3-linux:~ echo out > /sys/class/gpio/pioA3/direction??????????????? ?
root@sama5d3-linux:~ echo out > /sys/class/gpio/pioA9/direction??????????????? ?
root@sama5d3-linux:~ echo out > /sys/class/gpio/pioA5/direction??????????????? ?
root@sama5d3-linux:~ echo out > /sys/class/gpio/pioA7/direction

?

３ 配置ＧＰＩＯ初始化電平(繼電器全部關(guān)斷):?

root@sama5d3-linux:~ echo 1 > /sys/class/gpio/pioA8/value????????????????????? ?
root@sama5d3-linux:~ echo 1 > /sys/class/gpio/pioA1/value????????????????????? ?
root@sama5d3-linux:~ echo 1 > /sys/class/gpio/pioA3/value????????????????????? ?
root@sama5d3-linux:~ echo 1 > /sys/class/gpio/pioA9/value????????????????????? ?
root@sama5d3-linux:~ echo 1 > /sys/class/gpio/pioA5/value????????????????????? ?
root@sama5d3-linux:~ echo 1 > /sys/class/gpio/pioA7/value

?

4 配置QD((繼電器電源關(guān)斷)): ?

root@sama5d3-linux:~ echo 21 > /sys/class/gpio/export????????????????????????? ?
root@sama5d3-linux:~ echo out > /sys/class/gpio/pioA21/direction?????????????? ?
root@sama5d3-linux:~ echo 1 > /sys/class/gpio/pioA21/value

?

5 驅(qū)動(dòng)繼電器閉合((條件首先QD要閉合)):?

root@sama5d3-linux: echo ０ > /sys/class/gpio/pioA21/value

root@sama5d3-linux: echo ０ > /sys/class/gpio/pioA８/value　//ｙｋ０合

root@sama5d3-linux: echo 1 > /sys/class/gpio/pioA８/value　//ｙｋ０ 關(guān)

root@sama5d3-linux: echo ０ > /sys/class/gpio/pioA１/value　//ｙｋ１合

root@sama5d3-linux: echo 1 > /sys/class/gpio/pioA１/value　//ｙｋ１關(guān)

?
