AsProgrammer 2.1.0.13 is a free, open-source Windows-based software utility used primarily for reading, writing, and erasing EEPROM and Flash memory chips. It is the preferred alternative to the basic Chinese software often bundled with budget USB programmers. Key Features of Version 2.1.0.13
This specific version is part of the ongoing development to support high-speed and modern programming protocols.
Multi-Protocol Support: Compatible with SPI, I2C, and MicroWire protocols.
Hardware Compatibility: Built to work seamlessly with the CH341A USB programmer, but also supports hardware like the Bus Pirate, FT232H, and Arduino-based programmers.
Expanded Chip Database: Supports a massive range of 24-series (I2C) and 25-series (SPI) chips from manufacturers like Winbond, MXIC, and ST.
Portable Utility: The software is standalone (portable), meaning it does not require a standard installation and can be run directly from its folder. How to Use AsProgrammer
The software is commonly used for BIOS flashing, firmware recovery, and router repair. CH341A/CH347 Programmer : 8 Steps - Instructables asprogrammer 21 013 download free
AsProgrammer 2.1.0.13 is a widely-used graphical interface tool for reading, erasing, and writing serial memory chips, commonly used with the inexpensive CH341A programmer. It is an open-source, portable utility that does not require installation. 1. Download and Safety
The software is free and community-maintained. To ensure a safe download, use official or reputable developer repositories:
Official Releases: The primary source for binary releases is usually the Official GitHub Repository.
Version 2.1.0.13: This specific version is often cited in technician forums and guides for its stability and expanded chip support.
Safety Note: Always verify downloads with a security scan. Since this tool interacts directly with hardware, it may be flagged by some antivirus software as "potentially unwanted" due to its low-level access. 2. Setup and Drivers
AsProgrammer requires specific drivers to communicate with your hardware. AsProgrammer 2
Drivers: You will need the CH341PAR (parallel/API) drivers for programming tasks, rather than standard serial drivers.
Portability: Extract the downloaded archive to a folder. You can run AsProgrammer.exe directly from this folder without a full installation. 3. How to Use the Software Follow these steps to program a chip (e.g., a BIOS chip):
Connect Hardware: Plug your CH341A programmer (with the chip installed) into a USB port. Configure Hardware: In the Hardware menu, select CH341a. Detect Chip: Click the "?" (Read ID) button on the main toolbar.
The software will attempt to identify the chip type automatically. Operations:
Read/Backup: Always read and save a backup of the existing chip data before making changes. Erase: Clear the chip before writing new data.
Write/Program: Open your new firmware file (e.g., .bin or .hex) and click the write button. Introduction In the world of hardware hacking, BIOS
Verify: Always run a verification check after writing to ensure the data was transferred correctly. 4. Key Features of v2.1.0.13
Broad Support: Works with SPI Flash (25-series) and EEPROM (24-series) memory.
Enhanced Protocols: Supports protocols like I2C, MicroWire, and SPI.
Hardware Compatibility: Beyond CH341A, it supports UsbAsp, AVRISP-MKII, FT232H, and Arduino-based programmers. Releases · nofeletru/UsbAsp-flash - GitHub
