Turning an Arduino of virtually any sort into a simple AVR 6-pin ISP programmer is old hat. But when Atmel came out with a series of really tiny AVR chips, the ATtiny10 and friends with only six pi… ...

This USB driver is a firmware-only implementation of the USB 1.1 standard (low speed device) on cheap single chip microcomputers of Atmel’s AVR series! BootloadHID is a USB boot loader for AVR ...

AVR USBasp is a USB in-circuit programmer and it can use to program most of the Atmel AVR controllers. It simply consist of an ATMega8 and a couple of passive components such as resistors, capacitors, ...

Since the bootloader, including the USB firmware, is on the hefty side at 3.3 kB, [Dmitry] included hooks to re-use the bootloader’s USB code from within the target application.

Unlike most Arduino boards (ie. Uno), USB AVR based boards do not automatically reset when the serial monitor is opened. To see what your sketch outputs to the serial monitor from the beginning, the ...

This USB bootloader is only 1kBytes and implements the industry-standard DFU protocol that is supported under multiple Operating Systems via existing tools such as dfu-util and webdfu. It is a much ...

Hardware Startup's build includes: a USB to serial converter, an ATmega328p, a 5V power circuit, and some headers. Then, you load the the Arduino bootloader on the ATmega, connect everything up ...

This paper presents a new bootloader for Atmel's AVR ATMega microcontroller family. Presented solution compared to Optiboot is smaller and faster, leaving programmer more flash space, and reducing ...

Microchip has created an AVR microcontroller series with 12Mbit/s USB 2.0 and code protection. “As the next generation of Microchip 8-bit MCUs to integrate USB connectivity, the AVR DU family is ...
