This repository is focused on easy access to all firmware versions for this kit.
To be updated
The QCX kit includes a 2 x 3-pin standard AVR header for In-Circuit-Programming on the board. Many suitable AVR programmers are available inexpensively on eBay and elsewhere. They have a USB cable to connect to a PC. On the PC you need software such as avrdude (very popular command line driven tool), or Windows programs with graphical user interfaces to avrdude.exe, for example Extreme Burner, Bit Burner, or AVRDudess. All are free. When upgrading the firmware, ensure:
- Only use an original QRP Labs QCX firmware chip
- Program only the provided .hex file; do not change the Fuse settings, or other memories (e.g. EEPROM).
Simon VK3ELH wrote a tutorial on how to use an Arduino UNO and the AVRDudess program to update your QCX firmware.
This repository is just an easier way to access firmware written by Hans Summers for the QCX
