Is it possible to change the used GPIO pins on Raspberry Pi for the OM5577 Kit?

Hi everybody!

 

I am using the OM5577 Kit for the PN7120 on my Raspberry Pi 2 (running the OM5577 demo image). 

 

I wired the controller board directly to the pins of the Raspberry to get rid of the interface board and the controller works perfectly fine, but now i would like to add my display to the setup. The display uses the SPI interface and the PN7120 I²C, so i thought this should work.

 

The problem:

The display and the PN7120 controller are both using the pin#18 (GPIO24).

The display uses it for "Instructions/Data Register selection" and i think the PN7120 for resetting the chip.

 

 

Now I wondered if it might be possible to reassign the GPIO pins to use the pin#12 (GPIO18) instead of the pin#18.

 

 

Thank you!
