Step 1: Downloading the Correct "neoprogrammer 21 019 ch341a install" Package

Warning: Many third-party sites bundle adware. Always download from trusted sources.

Step 5: Your First Read/Write Operation

In NeoProgrammer, click the "Detect Chip" icon (microchip + magnifying glass).
The software will read the chip's ID and automatically select the correct IC from its database. (If it fails, manually search for your chip model).
To backup (READ): Click the Read IC icon. Wait 10-60 seconds. Click "Save" (disk icon) → save as backup.bin.
To write (PROGRAM): Load your firmware (File → Open). Click "Erase IC" → "Blank Check" → "Program IC" → "Verify IC".

Pro tip: Always verify after writing. NeoProgrammer does this by default if the option is checked.
