I'm trying to set up my PIC18F4550 for using USB, similar to this page: **broken link removed**. I'm not making that project (and yes I know the circuit diagram uses a PIC18F2550), it just shows the oscillator connections. In the circuit diagram it shows the 20Mhz oscillator connected between OSC1 and OSC2, but that the oscillator is also connected to ground. The 20Mhz oscillator I have bought only has two terminals - how does that work? do I just connect a terminal to OSC1 and OSC2 and leave out the ground?
Thanks!
Thanks!
