How to set the clock for USB apps ?
Posted: Mon Jan 12, 2009 10:20 pm
Hello !
I want to use a 18F2550 to play with the USB component.
First, I just want to send data from my PC to the 18F2550 and read the calculated DATA in return. Is the USB_HID is the best for me ?
Then, If i want to have the smallest PCB, Is-it possible the use only the internal oscillator ? No crystal will be great.
In the Pic configuration, I don't know how to set the first four lines to have 48 Mhz.
Any body can help me ?
Thank you very much and happy new year !!
