I'm using Visual Basic 6.0 with HID Method and PIC18F4550 for usb device = interface. All data can receive and transmite with successfull between = computer (VB6.0) and PIC18F4550. But the motion of animation flash is = not good (Not Smooth). The Flash animation is integrated with VB and = driving the animation also with VB. When i'm trying to change the HID with CDC (Virtual Comport) the Flash = Animation is good and smooth motion. Can anyone on this community help me, why the animation flash is not = smooth when i'm using the HID method??... What's wrong with this situation?? -- = Regards, _*Cluthax*_, *email : cluthax@gmail.com * " sent from my gedhangberry=AE wireless device " -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
