Using the software is straightforward, but requires attention to detail:
It is often confused with or used as an alternative to the CH341A Programmer software (the "Black" or "Green" versions), but Asprogrammer typically offers a more user-friendly interface and broader chip support.
AsProgrammer 2.1.0.13 is a popular, open-source software tool often used by hardware enthusiasts and repair technicians to program EEPROM and SPI Flash memory chips. It is frequently paired with the CH341A programmer
Click the button to ensure the software detects the chip manufacturer and type. Click "Read IC" to back up the current BIOS content. 4. Erase and Write (Flash) Asprogrammer 2.1.0.13
Understanding AsProgrammer 2.1.0.13: A Deep Dive into the Versatile Hardware Flasher
to unbrick motherboards, bypass BIOS passwords, or flash custom firmware.
: Always "Read" the existing firmware and save it as a backup. Click "Read IC" to back up the current BIOS content
Using AsProgrammer 2.1.0.13 requires a strict sequence of operations. Skipping steps often results in a chip that "fails to write" because the write-protection registers were never unlocked.
: When using version 2.1.0.13, ensure you have the CH341PAR driver installed rather than the "Serial" (CH341SER) driver to ensure the software recognizes the hardware in "Parallel/Programmer" mode.
: This version includes an updated chiplist.xml , supporting thousands of chips from manufacturers like Winbond, GigaDevice, MXIC, and Microchip . : Always "Read" the existing firmware and save
In the world of hardware flashing, . Older versions of CH341A software often suffered from "bit-flipping" or verification errors because they couldn't handle the specific voltage requirements or command sets of newer 1.8V or 3.3V chips.
For improved safety and efficiency, the core algorithms for reading, writing, and chip detection have been completely rewritten. This leads to more stable and reliable operations.
While synonymous with the , AsProgrammer 2.1.0.13 also supports: USBASP (for AVR microcontrollers) Arduino (used as an ISP programmer) FT232H (in bit-bang mode) CH347 (the high-speed successor to the CH341A) How to Use AsProgrammer 2.1.0.13 1. Installation and Drivers
