hi i am a student tryin to read the data between two spi devices by tapping the lines in the middle please help me if anyone hav a code to read the ss,mosi,miso,sclk signals using GPIO they vl jst act lyk input port n read
By the way - if you intend to read the signals using GPIO pins instead of SPI interfaces, that SPI communication better be slow.
It is no fun to implement a SPI slave in software. SPI is capable of many MHz while already low kHz speeds will start to be problematic in software.
