Thanks Sgt, your definition really give in-depth view the profound world of electronics to newbie like me...
Your help is very much appreciated.
I am now having issue getting the hardware for my PIC18 chip to work with the USB interface. I am using PIC18F14k50/PIC18F13k50 chip and had attached the connecting method for USB powered communication with my laptop. However, whenever i connect the circuit into my USB port, it will show that the USB Device is malfunctioned. I am sure that the correct usb driver is already pointed to, so that windows can install it. I am using "Simple USBLib" method to talk between the windows software and the PIC18 firmware...
The part that i am unsure is the hardware fixed-up of the PIC18, i had use the development kit schematic as a reference to derive the hardware circuit connection, but it still does not worked...
I had also tried the following:
- change the 150Kohm pulled-up resistor to 1.5kohm,
- removing the pull-up resistor
but all gave the same result as the device is shown as "unknown device" in the window hardware device page...
Please do kindly assist to advice if anybody has experience in setting up the hardware for PIC processor...
Thanks in advice...
