Nokia 5110 LCD Lib with another spi device

Recommended Posts

I have a problem with the simultaneous action on one hardware spi.

when I connect only LCD 5110 - everything works OK

when I connect only nRF24L01 (mirf library -> http://playground.arduino.cc/InterfacingWithHardware/Nrf24L01) - everything works OK

but when two devices is connected at the same time - program hangs :(


mirf lib uses SPI lib and LCD_5110 uses shiftOut...

how to make both devices work on one spi bus?
