3.6 GPIO Test
You can use “ls” to list all GPIO devices, and you should also see GPIO ports in
above table.
Example of testing GPIO
Set gpio200 GPI(in)
Set gpio201 GPO (out)
Set gpio201 GPO value “1”
Get gpio200 value
As you can see in above procedure A and B, we set gpio 200 as GPI and gpio 201 as
GPO, once we send data out from gpio 201, it should be able to receive the same
data from gpio 200.
