orangepi H3 and wiringPi (OP) with interrupts in Reviews, Tutorials, Hardware hacks Posted August 31, 2021 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 Michael 0

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.
