orangepi H3 and wiringPi (OP) with interrupts

Recommended Posts

Recently I tried to use CC1101 Radio-boards to access with spidev0.0; this works after some research:

1. activate spidev in the /boot/armbianEnv.txt (important)

2. in armbian-config hardware activate spidev

in the downloaded test routines the speed of the spi is set too high (8000000)

3. set this down to 4000000


In addition: I need the interurpt functions of GDO0 and GDO2 in the next test program.

As Interrupts on wiringOP seems to work not on all GPIO-Pins you have to select PAxx for example

After the change of the code for this PA21 wPI-Pin 11, it works as expected
