Here's my current version of the MPGuino software, metric version. It is not based on the metric version currently distributed by dcb, it is an evolution of 075metric that I posted last year.
It contains these "improvements":
- built with Arduino IDE 0020, targeting Atmega 328
- I have successfully used my Spiffie MPGuino and Freeduino platforms to program the 328 for a couple of people who asked for it, so far everything has been compatible with the "Official MPGuino" from dcb - just pop out the 168 from the Official MPGuino and pop in the 328
- added SKelly's font hack to make the large fonts more readable
- added big vehicle speed display
- added alternating L/100KM / MPG display for Tank and Current
- modified edit parameter to leave cursor under OK, instead of the first
non-zero digit
- don't calculate MaxLoop (for CPU % statistic) while the user is operating the configuration menu
- added Tank save to EEPROM, reload on power up
- added comments to the code
By the way, I've been concentrating on metric outputs and although the US gallons/MPG are still supposed to work - well, they haven't been testing in awhile. If anyone can test that and report back, it would be great.
I hope this helps somebody
