USB interface
A question, a problem or a suggestion, don't hesitate : a little email
An USB interface using a PIC16C765. Can be used :
- As an USB interface of a more complex project (in this case the PIC16C765 is a slave processor of the system),
- As a stand alone card (for USB->RS232 or tests for instance),
- As a programming support board.
For an easy testing, 8 leds are link with the B bus of the PIC16C765 (see SHOW_ENUM_STATUS of usb_ch9.asm given by Microship).

A picture of the board sized 4 inches by 4 inches (102 mm by 102 mm).
Schematic
The PIC and a RS232<->TTL converter, that's all.
2 options depending on :
- The supply through the USB bus or not,
- The need or not of the In Site Programming.
