Lub hom phiaj ntawm qhov kev qhia no yog los qhia cov ntaub ntawv xav tau los tsim daim ntawv thov siv GPIO tus pin ntawm DragonBoard 410c kev nthuav dav qis.
Cov ntawv qhia no nthuav qhia cov ntaub ntawv txhawm rau txhim kho daim ntawv thov siv GPIO pins nrog SYS ntawm Android thiab Debian kev ua haujlwm.
NCO TSEG:
Cov kab ntawv no muaj cov ntaub ntawv hais txog kev nthuav dav nrawm ntawm DragonBoard 410c.
Kauj Ruam 1: Kuaj Pins rau Tus Txheej Txheem Ua Haujlwm
- Rau txhua lub kaw lus ua haujlwm muaj kev qhia tshwj xeeb rau qhov qis qis nthuav dav pins;
- Tus pin taw qhia rau txhua qhov kev ua haujlwm tau pom nyob hauv 96boards cov ntaub ntawv rau DragonBoard 410c.
Kauj Ruam 2: Coj ntawm DragonBoard 410c
Xav txog Led txuas rau tus pin 23.
Kauj Ruam 3: Kuaj Pins - Android
Hauv Android, Tus Pin 23 yog GPIO938.
Kauj ruam 4: Nkag mus rau GPIO Via SYS ntawm Android
Nkag mus rau/sys/class/gpio directory:
cd/sys/chav kawm/gpio
Xav txog Led ntawm tus pin 23:
# ncha 938> xa tawm
# cd gpio938
Pab kom Led ua cov zis:
# echo "out"> kev coj
Qhib / tua Led:
# echo "1"> tus nqi
# echo "0"> tus nqi
Kauj Ruam 5: Kuaj Pins - Debian GNU/Linux
Ntawm Debian GNU/Linux, Tus Pin 23 yog GPIO36.
Kauj Ruam 6: Nkag mus rau GPIO Via SYS ntawm Debian GNU/Linux
Nkag mus rau/sys/class/gpio directory:
cd/sys/chav kawm/gpio
Xav txog Led ntawm tus pin 23:
# ncha 36> xa tawm
# cd gpio36
Pab kom Led ua cov zis:
# echo "out"> kev coj
Qhib / tua Led:
# echo "1"> tus nqi
# echo "0"> tus nqi
