RFM12B 433 transreceiver and ILI9340 tft display on Pro Mini - Problem using PIN

Hello to everybody,

I am using an RFM12B 433 Mhz transreceiver and a 2,2" tft display (ILI9340) on an Arduino pro mini.

The problem is, that both libraries (tft display and 433 transreceiver) are sharing some pin outputs (11,11,12,13) on my pro mini.

Both, the tft display and the RFM12B seem to work well. But my RFM12B receives strange values. I think it is an issue with the display because both sharing the pins mentioned above. If I disconnect the display the RFM12B works well!

This is how the RFM12B is connected:

Is it possible to let the tft display and the transreceiver to share pins?

The "easiest" way would be t change the pin settings in the corresponding libraries.
Or is there a better way to fix this issue?

Best regards,
Christian

Without knowing anything about your code? About your display? Who knows?
