Hi everybody,
I am trying to use USB commucation between VB and PIC 18F2550
it is working very good.. the problem is with the speed, the maximum speed i can reach is about 30 packets /s ; each packet is 64 bytes, even if i change the packet size the speed still the same (30 packets/s) . I tried to enable the high speed in the PIC nothing changed, anyway supposing i am working in the low speed i must reach higher speed with USB because:
30 * 64 = 1920 Bytes/s ( the serial port can go faster !!!) ...
what is the problem ??? is it in the VB ?? in the PIC program ?? in the hardware ??
if anybody worked on it and can help me, it will be great..
Thank you in advance..
