Earlier this month I talked about the Microchip PIC16C745 and PIC16C765, which are 8-bit microcontrollers with built-in low-speed USB. Since that time, I’ve got hold of one of these devices and built a simple USB peripheral with it. Click on the thumbnail for a bigger version of the image.

Summary: hardware easy, firmware tricky, software painful. Read on for more detail and some hints for anyone treading the same road in the future.

Fun devices of the month: Microchip’s PIC16C745 and PIC16C765. As well as the usual microcontroller features, these require only a couple of external components to function as low-speed USB peripherals.
