File content as of revision 183:a1fba6f76e69:
// main.cpp
//
//To Do:
// * Fix USB hot plug (must reset every time USB plugged)
// * Add 50% charge option
// * Add linear efficiency graph with 10 minute values
// * Add in-device config editor
// * Change pack volt color when CVLI fails
// * Add tire pressure cal (40psi for me = FR 38, RR 38.2, FL 37.8, RL 38 - maybe 2psi error on my tire gauge?)
// * Add on screen messages for heater on, etc, and use refresh feature above to clear in x seconds
// * Be more efficient with write buffer (use msgLen instead of always storing 8 bytes)
// rev183
// * Fix wrong whpg bug when charging away from home (now update and clear on each charge)
