I'm losing the will to live with the big display. It works, slowly, but causes a lot of problems for me with the critical alarms and warnings display etc. I'm not happy with that, so I'm going to remove it from future Master versions at the moment. Trying to be flexible makes it very hard
Greg you can use the code from the last version below that includes it if you want. I might re-visit it much later with Master MK2. Any updates/code changes from now on you will have to copy into this older version. Sorry Mate
Old version, last to include Big Display at this time, has issues with big display after an alarm occurs.

Note pressing button 5 on the menu simulates an Alarm condition for testing purposes.
***********************************
The version below has the Big Display removed and updated button config.
The buttons work as follows in the version below.
1) Toggle charge on/off
2) Show individual cell voltages
3) Enter security code
4) Set Alarm conditon for testing purposes Pack>AbsMaxTemp (While held down)
5) Set Warning condition for testing purposes Soc<10% Remaining (While held down)
Warnings now appear on the bottom line of the main screen.
Alarms cause display to change to negative, and display until condition which caused it has cleared.
