| |
Hello, I'm Carlo, I have a difficult task at work, my boss asked me to develop a driver SPI slave side on embedded ARM processor running Linux. Precisely linux occur on the SPI bus as a slave, not master as required by the hierarchical structure of the current kernel. The new driver will receive via interrupt and respond when selected by its chip select. Can anyone suggest the best way to develop this driver?. Personally, I have identified two main roads, the first if possible to exploit the structure SPI master driver, with a few tricks that now I can not define. The second most radical, write a driver for a UART like, but managing the SPI device. Thank you for any suggestions or examples.
