SPI not functioning correctly
I am using the Nucleo board with the nRF24L01P chip library (found here: https://os.mbed.com/cookbook/nRF24L01-wireless-transceiver). If I use two mbed chips, the rf chips talk to each other just fine. When I try the same thing with the nucleo, the default settings are different and the correct tx and rx registers cant be found. I took some screen shots of the spi signals of both mbed and the nucleo and they appear different but I dont know how to fix that. The nrf library seems to instantiate the correct polarity and phase of the SPI but nothing works. I have posted the screen shots and my code below.
