MiniSpartan6:...
MiniSpartan6: added ftdi chip config to switch between UART and Async FIFO. added few WIP designs with either spwlight core, FIFO_deom IP... Libs: added SpaceWire Light IP (Works really well!) started design of ahb_ftdi_fifo -> same protocol than AHBUART but over FTDI's Async FIFO interface. This might lead to much faster transfers UP to 12MB/s.
