In short, I’m trying to connect an NRF24L01 module and an SD card writer to the same Arduino, so I can receive data via the NRF and write it to the SD card. And the SD card writer is screwing up the SPI interface. As soon as I plug in the SD card’s MISO line, the NRF stops receiving and goes crazy spitting out blank lines.
This seems to be a known problem, from what I’ve been reading up on this forum. But all the threads I’ve seen discuss the issue, and in the end don’t really get anywhere.
Anyone got a definitive solution to this problem, to get these two to work together? In my case, I’ve got the SD card working perfectly on its own, the NRF working perfectly on it’s own, even a DS1302 module working perfectly on its own. And I’ve got the NRF + DS1302 working perfectly together. But when the SD card comes into play, everything blows up.
Using an Arduino Uno, with the standard NRF and SD libraries everyone else uses.
