Detailed Description
A software implemented SPI that can use any digital pins.
Useful when don't want to share a single SPI hardware among attached devices or when pinout doesn't match exactly to the target's SPI pins
#include "mbed.h" #include "SWSPI.h" SWSPI spi(p5, p6, p7); // mosi, miso, sclk int main() { DigitalOut cs(p8); spi.format(8, 0); spi.frequency(10000000); cs.write(0); spi.write(0x9f); int jedecid = (spi.write(0) << 16) | (spi.write(0) << 8) | spi.write(0); cs.write(1); }
