Summary of ATmega USB Programmer
This article provides a DIY guide for building a USBasp in-circuit programmer for Atmel AVR microcontrollers (ATmega8 or ATmega48). It includes schematics, PCB layouts, firmware hex files, Windows drivers, and a GUI for burning hex files. The programmer supports Linux, macOS, and Windows, offers up to 5 kB/s programming speed, and includes an SCK option for low-clock targets.
Parts used in the ATmega Programmer (USB):
- ATmega8 or ATmega48 microcontroller
- USB interface connector
- Crystal or resonator (as per schematic)
- Reset circuit components (reset button, resistor, capacitor)
- Voltage regulator (if required for target power)
- Decoupling capacitors
- Programming header (ISP 6-pin or 10-pin)
- LED indicator(s) and current-limiting resistors
- PCB (board for assembly)
- Miscellaneous passive components (resistors, capacitors)
