ASProgrammer is a lightweight, powerful flashing utility written by npro. It was designed to replace the archaic Chinese software (often named CH341A.exe or NeoProgrammer ) that typically comes with CH341A-based programmers.
ASProgrammer is a free, open-source, or donation-ware software tool designed specifically for reading and writing various types of non-volatile memory chips. Unlike generic flashing tools, ASProgrammer was built with a focus on:
Error reading chip ID: 21013 or Timeout on operation 21013 asprogrammer+21013
Users often report it is more stable than original manufacturer tools, especially for reading chip IDs correctly.
is a specialized, lightweight, portable desktop utility designed to read, write, erase, and verify memory chips via hardware programmers. Created as an alternative to clunky factory utilities, it interfaces with low-cost hardware adapters to directly interact with integrated circuits (ICs) on a binary level. Supported Hardware Programmers Unlike generic flashing tools, ASProgrammer was built with
