pikeyd doesn't work anymore on RPi3...

[dl9sec]

Pikeyd doesn't work anymore on my RPi3 (worked fine on my RPi1). It seems, that people having a RPi2 have the same problem.

Any ideas, workarounds, alternatives, patches?

It's funny you mention this cause I just got a Pi3 and can't get mine working with PikeyD either. I assumed it was my wiring job but perhaps there's a larger problem.

Could you describe exactly what happens? Does the program compile? Does it launch? Does it crash with an error message?

Thanks,
Zac.

Hi,

i spotted the problem:

On RPi2 and RPi3 the GPIO_PERI_BASE address has changed from 0x20000000 to 0x3f000000.
So just change #define GPIO_PERI_BASE in joy_RPi.c to 0x3f000000 and it will work like a charm on a RPi3 (couldn't test it on a RPi2) :-)

That's fantastic to hear thank you for solving this! I was having this and a few other problems and they're all fixed now. Can confirm this fix also works with any I2C MCP23017 (or MCP23008) chips too.

Thanks,
Zac.

Hi @dl9sec
I do not know how to do that, could you help me?

[porkus-rex]

Type into terminal-
sudo nano /home/pi/pikeyd/joy_RPi.c
Find the part of the files that's says-
0x20000000
To-
0x3f000000
Press Ctrl+x to save followed by Y followed by ENTER

[porkus-rex]

Depending when you installed pikeyd the file directory might be slightly differant

[apraetor]

It's line 43. Is this an issue relevant to all RPi 2/3 users? If so, maybe
a change to the source is in order? I know a little C (basically enough to
read existing code, not write my own), but not enough to set up compilation
directives.

I just submitted a change to remove the need for the hard-coded memory address of the GPIO pins. I was able to successfully run the same executable on Pi 1,2, and 3.

This is the change:
