ASProgrammer is a GUI-based tool used to read, write, verify, and erase flash memory chips. Unlike the official manufacturers' tools (which are often bloated or Windows-10 incompatible), ASProgrammer+ is lightweight, open-source, and actively maintained by the community (primarily on GitHub).
How does asprogrammer+21013 stack up against the competition?
| Feature | ASProgrammer + CH341A | NeoProgrammer | Flashrom (CLI) | | :--- | :--- | :--- | :--- | | GUI | Clean, simple | Cluttered but feature-rich | None (Command Line) | | Chip Database | 800+ chips | 1500+ chips | 1000+ chips | | Speed | Fast on CH341A | Moderate | Fastest | | Ease for 21013 clones | Poor (often fails) | Excellent | Good | | Best for | Quick BIOS fixes | Rare/unknown chips | Linux users & scripting |
Recommendation: If asprogrammer+21013 fails, download NeoProgrammer (formerly AsProgrammer fork). It handles the CH21013 typo clones much better.
ASProgrammer+ 21013 is a stable, intermediate-release build of the popular open-source EEPROM programmer. It is widely regarded as the "go-to" software for owners of CH341A programmers because it fixes compatibility issues found in the manufacturer's original software and supports the latest flash chips used in modern computers and electronics.
AsProgrammer is an open-source software alternative to the original CH341A programmer software, designed to read, write, erase, and verify data on various EEPROM and SPI flash chips. It is highly regarded for its stability and broader chip support compared to the default manufacturer tools. 1. Getting Started: Hardware & Setup asprogrammer+21013
Before using the software, ensure your hardware is properly connected:
Driver Installation: You must install the WCH CH341 serial/parallel drivers for Windows to recognize the device. Physical Connection: Insert your IC into the programmer.
24 Series (I2C): Use the slots furthest from the USB connector.
25 Series (SPI): Use the slots closest to the USB connector.
Pin 1 Orientation: Ensure the dot or notch on the chip (Pin 1) faces the lever of the ZIF socket. ASProgrammer is a GUI-based tool used to read,
1.8V Chips: For low-voltage chips (like the 25Q64FW), a 1.8V adapter is required to avoid damaging the IC or failing to program. 2. Software Guide: Using AsProgrammer
AsProgrammer is a portable application, meaning it does not require installation—just run the executable.
Select Hardware: Open the "Hardware" menu and select CH341A.
Identify the Chip: Click the "Read ID" (🔍) button. If connected correctly, the software will show the chip's manufacturer and capacity (e.g., W25Q64).
Backup First: Always click "Read IC" followed by "Save File" to create a backup of the existing firmware before making changes. designed to read
The Main Workflow: To flash a new file, follow these steps in order: Open File: Load your new .bin or .hex file.
Unprotect: If the chip is write-protected, use the "Unlock" or "Unprotect" function. Erase IC: Clear the existing data from the chip. Program IC: Write the new data to the chip.
Verify IC: This compares the chip's content against the loaded file to ensure no errors occurred during writing. 3. Common Issues & Tips
Verification Errors: If verification fails, it often means the chip isn't seated properly in the clip or socket. Try cleaning the pins or reseating the clip.
Power Constraints: Programming a chip while it's still on a motherboard (using a clip) can sometimes fail if the board's other components draw too much power.
Speed: AsProgrammer can sometimes be slower than other tools like Colibri, but it is generally more reliable for difficult chips.
