Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Did anybody experience any problems with GP15 ? Or did Peter have a fix already ?

I think it's only a problem if it's allocated to an internal peripheral (I2C2 or SPI2).

Hi Mick,,

On Peters VGApicomite it looks like GP15 is connected to an I2C header, or the RTC, or I have seen wrong...

Regards,

That doesn't mean that he's using the internal I2C module though. He might be bit-banging the PS/2 and just happens to be using that pin.

It works nicely anyway. :)

The problem seems to have been that it was used by a patch to the USB system during startup and wasn't being freed off properly. Or something like that, I didn't delve into it too far.
