We got these thingies from: https://web.archive.org/web/20100121014842/http://www.romonit.de/index.php?id=7
Is a tool from Mark Lord to reflash the product id of the romonit FDTI-cables. To use it you need to compile it and rewrite the eeprom on the FTDI-chip.
- sudo aptitude install libftdi-dev
- sudo ./ft232r_prog --old-vid 0x0403 --old-pid 0xbaf9 --new-pid 0x6001
After that, it's a normal USB-serial cable
Contains a small firmware for romonit devices to test the components. What works:
- 32kHz timer
- Battery gauge
- Temperatur and humidity display
Current consumption is 10uA for the LCD, 5uA (average) for measuring humidity and temperature every 8s and about 2uA for processing on the AVR.
