Version 2.1.0.13 is confirmed to work correctly on Windows XP, 7, 8, and 10 , whereas older versions had issues, particularly with Windows XP.
: It includes an extensive chiplist.xml that allows it to identify thousands of different ICs from manufacturers like Winbond, GigaDevice, and Macronix.
If you are programming a 32MB chip (like a W25Q256) but your CH341A only supports 24-bit addressing, use the "Split/Bank" feature. Asprogrammer 2.1.0.13 allows you to flash the chip in two 16MB halves by toggling the HOLD pin.

The range of officially supported programmers has been refined to CH341A and USBasp . This focus allows the developers to optimize and thoroughly test the software for these two popular, low-cost platforms.
The 2.1.0.13 release focuses on refining the user experience and expanding the database of supported chips. Key highlights include: Expanded Chip Database
Let’s break down the specific features you gain when using this version. Version 2
chips. It is often preferred over the manufacturer-supplied Chinese software because it offers a cleaner interface and more reliable verification processes. Core Functionality and Workflow
Version 2.1.0.13 consolidates support for key programming hardware. The focus is narrowed to ensure high stability for two of the most popular interfaces: the (often found in "gold" edition USB programmers) and the USBASP interface. While it supports fewer programmers than some bloated alternatives, the targeted focus results in more efficient and reliable code. This version also maintains support for hardware like the AVRISPMK2.
Upon launching the software, navigate to the menu. Select your specific device (e.g., CH341 ). Ensure the voltage levels on your programmer match your chip (3.3V vs. 1.8V) to avoid hardware damage. 3. Reading and Writing Asprogrammer 2
: Windows XP, 7, 8, 10, and 11 (32-bit and 64-bit architectures). License : Free and Open Source.
These are the main actions you'll perform. You can:
While Asprogrammer works with the CH341A, you must ensure you have the correct Windows drivers installed. Version 2.1.0.13 works best with the official CH341SER.EXE driver (version 3.4 or later).
As of 2025-2026, newer versions of Asprogrammer (2.2.0.x and beyond) exist. However, many technicians downgrade to because newer versions introduced:
