Marco Antonio Carbajal Posted June 20, 2023 Share Posted June 20, 2023 Hi. I am working with an Olinuxino A20 micro, but I have issues with the SPI bus. I hope somebody can help me to find a solution. I used Armbian 23.5 Bookworm with kernel 6.1 In sclk signal i have a pulse before to start the data transmission, I required the SPI to communicate a LoRa module but the pulse before of data generate that doesn´t work the LoRa module. I attached the signals. 0 Quote Link to comment Share on other sites More sharing options...
