Hello everyone, I am using a NanoPC T2 with Android 4.4, and I want to connect the device through SPI with an RFID-RC522 card reader. Previously I used the GPIO ports with serial communication without problems but I can not communicate via SPI.
I connect the SPI Port via pins 7,8,9 and 10.
I open the port without problems
HardwareControler.open ("/ dev / spidev0.0", FileCtlEnum.O_RDWR);
After configuring the port I use a timer to send data but without results.
Best Regards
