USB HID Device
This weekend I've managed to create my first USB device. It's a simple board with the PIC18F4550 microcontroller. It gets detected from Windows as HID device and works properly. I can send data to it and read information back. Tried the ADC and it works fine. I still have to make some test on the speed of the transfer but for my needs it's more than enough. I used the Microchip USB Bootloader and modified it a bit to work with the free version of C18 compiler. And so the device is able to update/program it's firmware/memory using the PC thought USB. So no need for my programmer for now. There is a design fault in the pictures below. The big capacitor over there under the LED is too big and the device was not working properly. I have now changed it with a 100nF capacitor and everything is fine.
So here are some pics:
