Connect your CH341A programmer to a USB port. Navigate to the extracted folder and double-click . Flashing a Chip with AsProgrammer
Clean the pins of the IC chip with isopropyl alcohol. If using a SOIC8 test clip, adjust the tension grip and shorten your jumper cables to minimize noise.
: Features a built-in editor that allows you to view and modify binary content (like changing a MAC address in router firmware) before writing it to a chip.
: Supports a wide range of affordable programmers including the CH341A (Black/Green editions), UsbAsp, CH347, Arduino, and FT232H. Chip Support asprogrammer 21013 2021 download
Version 21013 expects the original CH341A driver.
If your chip is 1.8V, you must use a 1.8V adapter, as the CH341A outputs 3.3V or 5V.
: Connect your IC to the programmer (e.g., CH341A). Ensure correct orientation, usually indicated by a dot for pin number one. Connect your CH341A programmer to a USB port
Use 7-Zip or WinRAR to extract the downloaded archive to a folder on your desktop (e.g., C:\ASProgrammer ).
Check your CH341A pin connection (ensure PIN 1 aligns) and ensure the chip is properly seated.
: The nofeletru/UsbAsp-flash repository often hosts the latest stable releases and community forks. If using a SOIC8 test clip, adjust the
Includes an "Auto Detect" feature for 25-series SPI chips to automatically identify the manufacturer and model.
For AsProgrammer to talk to your CH341A hardware, you must install the parallel driver (not the serial/TTL COM port driver). Download and execute the official CH341PAR.EXE installer. Click and wait for the success prompt. Step 2: Extract the Software
