Use with Raspberry Pi

[bmalcheski]

I am trying to refill cartridges using the GPIO pins on a Raspberry Pi to read/write the eeprom. Does Stratasys-ng expect the data file to be in binary?

What I am doing is taking the dump from the GPIO directory, opening it using Vi in hex mode, copy the data to another text editor, remove all of the spaces etc. I save that as a text file which I copy into HxD on my windows machine where I then save it as a .bin. However, the data will not decrypt for me. Is there a better way of doing this so that I am less likely to be causing errors?

Another place I may be having an issue is with the chip serial number. When I look up the serial using my Bus Pirate it differs from what the GPIO directory on the Pi calls it. Which one should I believe?

Thanks in advance!

Hey!

Yes "stratasys-cli.py" expect a binary file as input. I just fixed a typo in a serial number when using the "fox" machine type, maybe it was the issue?

I've also merged stratasys-ng into master, so you may want to pull the repository and delete the "stratasys-ng" branch.

Thanks for the info. My machine is a prodigy.

I've added two scripts to read/write to an cartridge using a buspirate, you might want to try them.

Those scripts are awesome. Thank you so much! I'm having a problem with printing the eeprom data though. I enter this into the command line: python stratasys-cli.py eeprom -t prodigy -e 0e00000160aa0e23 -i ETeeprom.bin

and I get "TypeError: unpack-from() argument 1 must be string or read-only buffer, not byte array."

I assume I am doing something wrong but can't figure out what.

Thanks for the help.

I tried another eeprom and although I got a current quantity checksum error it seems to be working for that eeprom. I had been experimenting with the old refill method on some of these eeproms and likely messed the data up while doing so.

However, when trying a brand new support material eeprom (from a 3rd party material supplier) I still get the TypeError.

Ok, I just remembered the issues with Python 2.7.3. I just have to get my Ubuntu to install a newer Python. I tried 2.7.6 but I ended up getting a unicode mismatch between python and pycrypto...

I can FINALLY read the data on an eeprom. I've been trying to get cartridge refills working for longer than I care to admit. Thank you so much for these awesome tools!

The Bus Pirate read script works like a charm!

Got the machine to read my eeprom! Thanks again!

Hi Ben, I've been working hard on this as well. Could you drop me a line to chat about this? creativechemist at netscape dot net
