USB Serial Communication Continuous

[pic-ker]

I've never tried with a DEFINE OSC 20... but i think it's the main problem.

Look how i did it in mine. (config fuse as well)

I have tried it with a DEFINE OSC 48 as well....infact the USB interface works fine...i tried to switch on/off the LED pins on you demo and they work ...

The config fuses are
24 0E 3E 00 00 83 81 00 0F C0 0F E0 0F 40

in either case (48 or 20)
i have defined the PLL and OSC setting in the .inc file so the DEFINE directive has no effect


in the case of :

DoLow:
LOW PORTC.0
USBSERVICE
PAUSE 30
USBSERVICE
return

i found that this code does work...and it does generate a delay of 30ms on the Oscilloscope without affecting the Tx USB connection....The TX seems to be transmitting fine...
