Based on Sanni's cartreader firmware
Requires SEGGER Embedded Studio (6.22a recommended)
To build the firmware open GDCartReader.emProject in Embedded Studio, then right click Project 'GDCartReader' and click Build the compiled firmware can be found at ProjectFolder/Debug/Exe/GDCartReader.bin, you will need to rename this file to update.bin which can now be put at the root of your SD Card to update your BurnMaster
Alternatively you can simply clone this repository and make your changes, Github will automatically build your firmware (See Actions Tab)
This repository is setup to auto-build the firmware when a commit is made, builds can be found under the Actions tab, this makes it really easy to fork this repository and make your own changes without having to download Segger Embedded Studio
This source code is provided directly by funnyplaying, i have nothing to do with the development of the firmware.
