USBasp is a USB in-circuit programmer for Atmel AVR controllers. It is based on Thomas Fischl's USBasp design project. The USB interface is achieved by using an atmega8 processor and the rest is done in firmware.

The firmware are free to load from USB in-circuit programmer for Atmel AVR controllers. It is based on Thomas Fischl's website. You can download Windows drivers from here, so you can use them on Windows Vista and above without any issues. The driver will work on both 32 and 64 bit platforms. For Linux and Mac OS X no driver is required, just use AVRdude and specify the correct port.

The AVR programmer will work with a wide variety of Atmel AVR microcontrollers including the Atmega8a and Atmega168a. A list is available of supported microcontrollers are shown below.
