Before connecting your CH341A programmer, you need to install the appropriate drivers:
| Button | Action | |---|---| | | Auto-detects the chip ID (if supported) to confirm physical contact with pins. If detection fails, do not proceed. | | Read IC | Immediately hit "Read IC" to backup the original contents. Save as original_backup.bin . This is your "undo" button. Never skip this, even if you think you have a clean firmware file. | | Erase IC | Perform a "Chip Erase" to clear the memory completely. | | Blank Check | Run a "Blank Check" to ensure the chip is truly empty (all 0xFF). | | Open | Load your new firmware (the BIOS file or bootloader). | | Write IC | Click "Write IC". Enable the "Verify" checkbox in the dropdown menu next to the button. | | Verify | After the write is complete, run a manual "Verify" to compare the buffer with the chip contents. |
