Reversed output current direction #90

The output voltage polarity and current direction does not match what is printed on the front panel.

Quoting the MAX1968 datasheet, when (VCTLI - VREF) > 0, VOS2> VOS1, so the Peltier_pos and Peltier_neg net labels in the schematics is a bit misleading.

gkasprow commented 3 years ago

right. Shall I call the signals Peltier 1, Peltier 2?

TopQuark12 commented 3 years ago

I'm more concerned about the labels on the front panel, which should have the TECx+ and TECx- labels swap positions. As for the net names, renaming them or swapping net names would work imo.

gkasprow commented 3 years ago

OK, I swapped labels on schematics and also swapped panel labels
