Did you configured the SPI itself in FEX using FEX Guide ?

rezaee got a reaction from Igor in How to make SPI TFT01-2.2S LCD working on nanopi-m1?I have solved the problem on github. you can see ther result there if you want!

rezaee reacted to Igor in How to create a one-purpose computer?If you want to save additional few months, than start with our building system. Its less complex than buildroot and it's working with all boards from download section.

I use buildroot https://buildroot.org

rezaee reacted to rezaee in How to create a one-purpose computer?Hi
I think the subject I am interested in, called Kiosk OS or computer.
I like to build a computer that when you turn it on, it does only execute one or some programs that I want. how can I do that? Is it a simple thing or should I spend weeks or months to learning and doing that? (I am a newbie linux user but know the C language).
Very thank you in advanced!

No I didn't check voltage levels(I have no equipment at now) but my motor running with 3 to 5 volts and it works when I connect it to 3.3 or 5 volt pins.
I think the problem is in kernel and gpio drivers maybe!

Be aware that GPIO pin is capable sourcing only about 20 mA of current which is waaaaay too low for running any kind of motor. You need to put some kind of transistor in betweeen, like MOSFET. You have plenty tutorials on the net.

rezaee reacted to zador.blood.stained in How to control a simple dc motor with nanopi-m1 that has armbian 5.20?You can't run a motor directly from GPIO since it won't provide even near enough current. You need to use a relay, a transistor or a special motor control IC, otherwise it won't work.
Also physical pin 10 is GPIO G7 which would be pin 199 for sysfs interface.
