We worked on the FPGA this last days.
While I was working on controlling the LED driver, Felix and Sylvain worked on the communication with the gumstix. The news are good :
- the communication between gumstix and FPGA is now working. But, the module for the communication must be modified because, in our real system there will be 2 clock : the FPGA clock and the gumstix clock (just for the data transmission). Felix and Sylvain have finished to implement this new architecture but, it must be tested.
- the control of the LED driver is perfect: we can now turn on all the LED on the propeller, choose the color and the intensity
The next steps are controlling the LED thank to the gumstix and, writing in the external RAM.
