Kwan Xian Posted April 4, 2019 Share Posted April 4, 2019 HI, guys! I tried to enable spi connect RC522 on OPi_PC(H3). It works! my topic: but now, I make the same way to enable spi with RC522 on OPi_PC2(H5). I can found spi on "/dev/spidev0.0" But when I run "Read.py" script as root. It can't detect & read the cards. How can i use it on OPi_PC2? 0 Quote Link to comment Share on other sites More sharing options...
Kwan Xian Posted April 8, 2019 Author Share Posted April 8, 2019 SOLVED: Because PC2 GPIO pins is different. change SPI0 to SPI1 edit /boot/armbianEvn.txt "param_spidev_spi_bus=0" --> "param_spidev_spi_bus=1" save! 0 Quote Link to comment Share on other sites More sharing options...
