Support for more (similar) devices.

[DaveDavenport]

The device with productId 0x21d7 (2 higher) also works with this code.
Might be an idea to add an option to add for multiple productIds.

[alex-t-grecu]

With small parsing changes I can report the code will work also with productId 0x21cc which is one of the first glucometer models from the same company. Indeed it would be great to integrate support for as many devices as possible. I bought the device some time ago (at least 5 years) and it still works pretty fine, but unfortunately I could not extract the measurements before because it did not come with the software... Please, let me know if you're willing to continue development on the code.

[emogenet]

@DaveDavenport : e71afe3 should do what you want. NB: code currently makes no attempt to check if devices you add to config.txt are actually compatible.

[emogenet]

@alex-t-grecu would be very happy to add support for more devices. Please send me your "small parsing changes" so I can integrate them.

[alex-t-grecu]

Hi @emogenet , the patched version of the code which I just used to read again all values from my device is in the forked version of the main.cpp. I also modified config.txt to include the device ID. Here are some further details about the changes...

Some extracted data/measurements for a previous user with type-II diabetes (I cannot understand yet what the "status" field represents, but it should include information about the conditions when measurement is done e.g. pre/post-prandial. I can only keep an eye on values as I'm doing more measurements)

Added config for Roche ACCU-CHEK Guide Me, plus instructions for raspberry pi debian installation of the correct libraries. PR submitted.

Okay I tried adding usb ID of Accu-Check Active in config.txt and I got a segfault.
