AsProgrammer Dregmod Allow You to Program Flash
It is an actively maintained fork of the original AsProgrammer (nofeletru/UsbAsp-flash). The description matches the official project page exactly:
AsProgrammer Dregmod Allow You to Program Flash
Only four wires, and the board labels every one of them. Reading down the header:
| board pin | Bus Pirate pin |
|---|---|
| +5v | VOUT, the on board supply |
| SCL | IO1, the clock |
| SDA | IO0, the data line |
| GND | GND |
“AsProgrammer dregmod allow you to program flash memory on the protocols spi, I2C, MicroWire. Supports Buzzpirat, Bus Pirate, CH341a, CH347, UsbAsp, AVRISP(LUFA), Arduino & FT232H.”
Supported Protocols & Chips
- SPI (mainly 25-series NOR flash, e.g., Winbond W25Qxx, SST25, etc.)
- I2C (24-series EEPROMs)
- MicroWire
It can dump chips to a file, flash new images, and verify with CRC/checksums.
Supported Hardware Programmers
- Buzzpirat / Bus Pirate v3.x
- Bus Pirate v5 / v6 / v7 (native support added in recent versions)
- CH341A / CH347
- UsbAsp
- AVRISP (LUFA)
- Arduino
- FT232H
Latest Version (as of late 2026)
v5 (released 20 August 2026) is the current latest. Major improvements include:
- Full native support for Bus Pirate 5/6/7 (BPIO2 protocol)
- Improved Bus Pirate v3.x performance (up to ~8× faster)
- New I2C bus scanner (address map + one-click address selection)
- No external Bus Pirate DLL required (pure Pascal implementation)
- Smoother GUI (live COM port list, fewer freezes)
- Merged upstream chip support and reliability fixes
AsProgrammer dregmod is a free, open-source Windows tool for reading, writing, erasing, and verifying flash memory chips.
