1 Chip USB AVR Development

Wouldn’t it be nice if there was an AVR microcontroller with USB device support built in so you would not need a separate programmer or serial link? Well in fact there are quite a few of them, and this awesome tutorial (google translate) is a quick and easy crash course in using the ATMega 16/32U4 micro controllers.

These 8 bit AVR’s (16k and 32k) have the usual list of features you would expect in a Mega AVR. 26 GPIO pins and a pretty easy to solder 44 pin surface mount package, the micro controller also has a USB 2.0 Full-speed/Low Speed Device Module and allows programming though a standard bootloader.

Once you have a pretty standard board assembled you need Atmel’s FLIP RS232, USB, or CAN device programming software (Windows or Linux) and your favorite AVR IDE setup, you’re good to go!
