Pierre and I worked today together and we managed to implement an SPI bus over GPIO driver. We fuund the way to directly set the GPIO value without all the time wasted by standard GPIO functions. It’s 16 faster than yesterday! Now sending messages to our LED drivers will be made at 8Mbits/s! As a consequence the bit rate is now sufficient and will be able to display holograms without lagging. We also almost finished codding our HARP driver and our main program. It will just open the driver and write to him to send data. The HARP driver will take care of all the communication with the LED drivers.
Tomorrow we’ll test them !
