Hi,
I'm trying to build fast 8 channel PC based logic analizer but I'd like to upload the scan in real time.
For 10MHZ clock and 8 ch I need 10MByte/sec upload speed. Using PIC18F4550 I cannot get that speed.
I tried also FT245R USB fifo but the max transfer was 1MByte/sec.
Is there a similar to FT245R chip with better upload speed using high-speed USB 2.0?
I have a hard-drive to usb converter and it's working up to 30-40MByte/sec. Is there a way to simulate the hard drive protocol and to upload the real time scanning?
Any suggestions are very welcome. Thank you in advance!
