High speed MCU to PC transfer

Started by russ...@gmail.com August 14, 2006
Hi everyone,
If you dont mind im just after some of your thoughts regarding a
project that im working on.
I intend to transfer about 770KiB / s (kilobytes) from the PIC18F4550
(USB 1.1 controller) to a PC (will be audio samples). just wondering if
anyone has had any experience with this and what sort of work on the PC
software/driver side needed to be done... I cant really write in C++
(or anything) but i know someone who can help me...

Russell, not going to happen! Taking into account the overhead of USB you you expect too much. The best rate I have seen was about 500 kBytes/sec sustained using a 32-bit micro. Assuming the PIC18 is fast enough and does not contribute as additional bottleneck, I would be very surprised if you can get about 500 kB/sec An Schwob
