2.1.0.13 [better] Download: Asprogrammer

AsProgrammer 2.1.0.13 is a specialized, portable software utility used for reading and writing firmware to EEPROM and SPI Flash memory chips, most commonly via the CH341A programmer. It is a popular alternative to the standard Chinese software provided with these programmers because it offers better chip compatibility and a cleaner interface. Key Features

Project provenance and forks

Primary upstream: UsbAsp-flash / AsProgrammer family on GitHub (repositories such as nofeletru/UsbAsp-flash and associated AsProgrammer builds).
Community forks and mods: therealdreg/asprogrammer-dregmod (adds Bus Pirate integration, additional features), other forks providing builds or extended chip lists.
Many authors are individual open-source contributors; licensing is typically MIT for parts of the tool (confirm per repo).

This version is a classic iteration of the GUI-based programmer often used with affordable hardware like the CH341A USB Programmer. Unlike many proprietary tools, AsProgrammer is portable, meaning it does not require formal installation and can be run directly from an executable file on various Windows versions, including Windows 7, 8, and 10.

What it does

Detects and reads chip ID.
Read, write, erase, verify flash/EEPROM contents.
Support for many chip models and variants (Winbond, MXIC, GigaDevice, etc.).
Unprotect/protection register handling and scripts for chip-specific operations.
Plugin/mod support and community forks add extra device support (CH347, Bus Pirate, dregmod).

Interface: The UI is functional but dated; it may feel overwhelming for absolute beginners. AsProgrammer 2

Step 1: Extract the Files

Use 7-Zip or WinRAR to extract the zip archive to a folder (e.g., C:\Asprogrammer). No installer is needed—Asprogrammer is portable. This version is a classic iteration of the

Verify: Always perform a Verify after writing to ensure the buffer matches the chip's content. ⚠️ A Note on Voltage
