You can send any multiple of 128 complex samples. No need to hack the
host library. Take your pick: 128, 256, 384, 512
Eric
Am I correct in saying then that the max_bytes variable determines the number of samples sent? I'm not sure but the verilog seemed to be able to cope if the number of
samples was some other value besides 128 or any multiple of it. I'd really like to be able to control the number of samples that go to the board exactly.
