How to send and receive data to custom FPGA logic via USB

Post by tich »

I need guidance on how to send and receive data to custom logic via USB. I plan to make changes to the fifo_reader and fifo_writer.

If you are interested in exchanging PDUs between the host PC and FPGA logic please take a look at the packet_control_t interface that the bladeRF-wiphy project utilizes. Effectively, packet_control_t is an interface for allowing fifo_writer and fifo_reader to exchange variable length payloads with the host PC (as opposed to IQ samples).
