Why WinUSB? Unlike libusb, WinUSB has better timeout handling, directly solving the 21013 sync errors.
Before changing any data, click . Once the hex editor view fills with your current firmware data, go to File ➔ Save As and back it up as a raw .bin file. Step 4: Erase the Chip
Order two CH21013s. They’re cheap, and it’s nice to have a spare when you accidentally short something.

: Use the slots closest to the USB connector.
Ensure the chip is placed correctly in the ZIF socket of your programmer, or use an SOP8 test clip for in-circuit programming. Pay close attention to (indicated by a dot on the chip casing), aligning it with the marked pin on the programmer. Step 2: Configure and Detect the IC
: Open the "Hardware" menu and select CH341A . Why WinUSB
Click the Read ID button (icon with a question mark). If successful, the software will automatically identify the manufacturer and chip model (e.g., W25Q64FV ).
ASProgrammer.exe -i -d -v -s 1000000
: 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. Once the hex editor view fills with your
ICs, an inline logic-level shifter adapter must be paired with the programmer to prevent permanent hardware damage. Development and Compilation Guide
Thump. Thump. Thump.
The structure of the term—combining "asprogrammer" (a professional descriptor) with "21013" (likely a unique numeric suffix)—suggests a standardized naming convention often used when common usernames are already taken or to maintain consistency across multiple services.
