is a lightweight, cross-platform GUI application designed for reading, writing, erasing, and verifying EEPROM, Flash, and microcontroller memory. Version 2.1.0.13 represents a stable release with enhancements in device support, user interface, and low-level USB communication.
In the world of hardware hacking, BIOS recovery, and embedded system repair, the ability to read, write, and erase non-volatile memory chips (like EEPROMs and SPI Flash) is indispensable. For years, the go-to solution for hobbyists was a combination of two things: the ubiquitous, $5 USD CH341A black/blue programmer board, and the increasingly unstable version 1.18 of Asprogrammer. Asprogrammer 2.1.0.13
Before dissecting version 2.1.0.13, let’s establish the basics. Asprogrammer is an open-source Windows-based utility originally designed to interface with the USB interface chip. The CH341A is a cheap USB-to-serial bridge that also supports synchronous serial (SPI) and parallel communication modes. For years, the go-to solution for hobbyists was
