Using OLED, RF Transceiver, and SD card together

Other Hardware Displays

I am having problems with the OLED, RF Transceiver, and SD card reader/writer working together. The code compiles fine but nothing shows up on the OLED screen. When I take the sd card and transceiver libraries out, the screen works fine. I am assuming that I need to have each module turn on/off with chip select but I cant find it in any of the libraries. The sd card's chip select works but I would like to know if there is a way to assign them to the other modules. I would appreciate it if someone would help me with this issue.

U'll find many posts discussing problems with SD.card_readers and the SD-lib. (not releasing MISO)

a) Try with the newer SDfat-lib
b) Change hardware so your reader 3-states MISO when not selected

I tried to use a different library for the SD card but it isn't my problem. I need to turn on and off the slave select on the Oled and the transceiver, I already have access to the ss on the SD card reader. Is there another library that will allow me to control the ss of the Oled and transceiver?
