WebFeb 20, 2015 · Do a bit of googling on software SPI. I see lots of implementations. One in the Arduino libraries - open source. And others. Master asserts chip select (a GPIO output pin connected to the slave device's chip select). Webing the SPI-transfer routine only to communicate with slave devices prevents collisions. Microcontrollers without hardware support for SPI also can communicate with SPI devices, because it is feasible to per-form a “bit-banging,” an all-software port implementation. Any microcontroller’s general-purpose-I/O pins can serve as SPI pins. bisho to mthatha
