USBasp - USB programmer for Atmel AVR controllers

USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply consists of an ATMega48 or an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed.

Features

• Works under multiple platforms. Linux, Mac OS X and Windows are tested.


• No special controllers or smd components are needed.


• Programming speed is up to 5kBytes/sec.


• SCK option to support targets with low clock speed (< 1,5MHz).


• Planned: serial interface to target (e.g. for debugging).

Drivers

On Linux and MacOS X no kernel driver is needed. Windows requires a driver for USBasp:

Note: Windows Vista/7 x64 requires drivers with digital signature. Currently there are no official drivers for libusb (USBasp software is based on it) with such a signature. Users reported that there is a tool named "Driver Signature Enforcement Overrider" to avoid the signature check.

Software

• AVRDUDE supports USBasp since version 5.2.


• BASCOM-AVR supports USBasp since version 1.11.9.6.


• Khazama AVR Programmer is a Windows XP/Vista GUI application for USBasp and avrdude.


• eXtreme Burner - AVR is a Windows GUI Software for USBasp based USB AVR programmers.
