There is no "update" command. I could probably add one but for now take the output from `eeprom_decode`, change the field `current_material`, then re-encode with `eeprom_encode`.

Yes you need to be `root` to write to the EEPROM file (so use `sudo`!)

you need to update those fields: ``` cartridge.current_material_quantity = cartridge.initial_material_quantity cartridge.last_use_date.FromDatetime(datetime.datetime.now()) cartridge.manufacturing_date.FromDatetime(datetime.datetime.now()) cartridge.serial_number = get_random_serialnumber() ```

try this: stratatools eeprom_decode -t prodigy -e a7027800000023 /sys/bus/w1/devices/w1_bus_master1/23-0000007802a7/eeprom > /home/pi/Desktop/cartdump.txt

hmm I never heard of someone having this problem before. What is the family code of the chip you are using?

Hi, It's not the first time I hear about this material id (0xfff) but I'm not sure if it's a valid material? Maybe it's a sentinel to let the printer...

You need to install pycrypto: http://www.voidspace.org.uk/python/modules.shtml#pycrypto

Hi, thanks for your patch. Which version of python are you using?

Did you try with the "prodigy" machine number?
