romonit

We got these thingies from: https://web.archive.org/web/20100121014842/http://www.romonit.de/index.php?id=7

Some more info is here: http://www.conrad.de/ce/de/product/108020/Romonit-econom-climat-Datenlogger-Messschreiber-5-bis-35-C

ft232r_prog-1.24

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.

http://rtr.ca/ft232r/

  • sudo aptitude install libftdi-dev
  • make
  • sudo ./ft232r_prog --old-vid 0x0403 --old-pid 0xbaf9 --new-pid 0x6001

After that, it's a normal USB-serial cable

fw-mm

Contains a small firmware for romonit devices to test the components. What works:

  • LCD
  • 32kHz timer
  • LED
  • Button
  • 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.
