The built-in logic script now properly automates the structural pipeline. This prevents the user from accidentally bricking a chip due to a lingering write-protection bit in the status register. AsProgrammer CH341A Download (2026) - DisplayMonk
AsProgrammer was created by a developer known as (often found on the 4PDA forums) starting around late 2011. It began as a utility for the UsbAsp programmer but quickly evolved to address a major problem for computer technicians and hobbyists: the lack of reliable software for the ultra-cheap, mass-produced CH341A programmer . The "21013" Breakthrough
ASProgrammer functions by bridging the gap between desktop software UI and low-level hardware registers on external chips. Modern versions emphasize safety, extended chip profiles, and dual-IDE cross-compilation environments.
The most important change in version 2.1.0.13 is the correction of a specific error. In previous versions, converting files from .bin to .hex format would omit an "extended linear address" field every 65536 bytes. This bug could cause data misalignment when loading firmware into some compilers or simulators. . asprogrammer 21013 new
Always export your custom JSON settings before initiating the update.
Once you have mastered basic flashing, leverage these hidden features in the :
, a specific iteration of the software maintained by developer Alexander Gavrilov. Key Features of AsProgrammer Broad Hardware Support : It natively supports various programmers including AVRISP-MKII Newer Device Compatibility : Recent updates have added support for the (allowing for adjustable clock speeds) and the Chip Versatility : It is highly regarded for its ability to handle both I2C EEPROM chips with high success rates. Lightweight GUI The built-in logic script now properly automates the
Click “Auto” (which now conveniently sequences: Erase → Write → Verify). The ASProgrammer 21013 new improves the erase timing for large chips, reducing the total cycle time by approximately 25%.
Unlike commercial software that often locks advanced features behind a paywall, ASProgrammer has thrived on community feedback and rapid iteration. The version represents the culmination of user-reported bug fixes and feature requests from the past 18 months.
The most common complaint with older versions was limited support for newer flash chips used in modern motherboards and IoT devices. The includes an updated devices.txt file with support for: It began as a utility for the UsbAsp
The version is an essential upgrade over version 1.41. With better support for modern, low-voltage flash chips, refined security in unlocking, and a more usable interface, it remains the most reliable free tool for BIOS and EEPROM flashing with a CH341a programmer in 2026.
Add a __debugbreak(); macro into your local C++ DLL source code at the precise function you want to evaluate.
Open the source directory containing the driver logic, typically under asprogrammer-dregmod\software\buzzpirathlp\ .
If you are still using a version of ASProgrammer from 2022 or earlier, you are working with suboptimal speed, limited chip support, and potential bugs that have been squashed in the release.
