Raspberry Pi 2, Piface Digital 2 interrupt #30

Closed drmod3 closed 8 years ago

drmod3 commented 9 years ago

There seems to be a problem with simple InputEventListener. The emulator works as well as output pins and input pins. After trying several programs, I attempted the examples. Blink works, presslights does not, whackamole does partially. Two boards and 3 SD cards have been tried, with update and upgrade following instructions.

Have I missed something?

Additional information has been observed. When rebooting, an error flashes by which says: "Error loading module spi-bcm 2708 no such module."

lsmod shows: spi_bcm2835 4253 0 also shows: snd_bcm2835 19761 6

/lib/modules/4.0.8-v7+/kernel/drivers/spi/ has two files: spi-bcm2708.ko and spi-bcm2835.ko The actual device shows to be bcm2709.

Thanks for any help on resolved the interrupt issue, which appears to be related to the bcm module

presslights.py seems to be working for me after a fresh install of wheezy. Are you using the latest software?

sudo apt-get update && sudo apt-get upgrade

I have just had this happen to me after a raspbian apt-get-update/upgrade cycle Initially spi dodn't work at all posy upgrade, with the error given above, until I changed my modprobe line to 2835

Now I can read and write pins fine, but interrupts are still not working....any ideas?
