AC-PG-USBASP USBASP AVR Programmer User Guide Version 2.0 18 January 2012 1. Overview 1.1. Introduction USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply consists of an ATMega8 and a few passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed. Some of the key features include: a. Works under multiple platforms. Linux, Mac OS X and Windows are tested, b. Programming speed is up to 5kBytes/sec, and c.
AC-PG-USBASP USBASP AVR Programmer User Guide Version 2.0 18 January 2012 Acronym and Abbreviation Description AVR According to Atmel, AVR stands for nothing, it's just a name. Others say it stands for Advanced Virtual RISC. However, the inventors of the AVR series chips are named Alf Egil Bogen and Vegard Wollan, so you be the judge.

USB Type A The USB end of the programmer connects directly into your computers USB port. 2.2. ISP – 10 pin IDC The 10 pin ISP connection provides an interface to the microcontroller.
AC-PG-USBASP USBASP AVR Programmer User Guide Version 2.0 18 January 2012 2.3. JP1 – Supply Target This jumper controls the voltage on the ISP VCC connector. It can be set to +3.3V, +5V or disable this jumper if the target device has its own power source. 2.4. JP2 – Self Program This jumper is used to update the firmware of the USBasp programmer. In order to update the firmware you will need 2 programmers. One to be programmed and the other to do the programming. 2.5.
