Summary
This article provides a comprehensive DIY guide to building a USBasp programmer for Atmel AVR microcontrollers, specifically the ATmega series. Utilizing an ATmega8 or ATmega48 as the core IC, the USB programmer connects via USB and supports multiple operating systems including Linux, Mac OS X, and Windows. It features a programming speed up to 5kB/s and supports low clock speeds. The guide includes schematics, PCB layouts, firmware hex files, Windows drivers, and software for burning hex files, all without requiring special or surface-mount components.Parts used in the USBasp Programmer for Atmel AVR microcontrollers:
- ATmega8 or ATmega48 Microcontroller
- USB Connector
- Crystals or Oscillator (implied for clock)
- Resistors
- Capacitors
- LED indicators (optional)
- PCB (custom designed for the project)
- Programming header for target AVR IC
