LiPo chargers again

Preamble

Following on from GhettoVaper – an extended GhettoVape III, I thought that I would add, if possible, the ability to balance charge the LIPos via a micro USB port. However, as the battery configuration is 2P, and not 2S, it may not be possible.

This time we are looking at PCB chargers, and Battery Management Systems (BMS).

NewPWM.ino:13:17: fatal error: PWM.h: No such file or directory

I searched google for ages, couldn’t find anything. Then, finally, I searched on Stack Exchange Arduino and found this answer from Mavidad, to Generating PWM signal 1-2 ms @ 333 Hz). NewPWM requires PWM.h from GoogleCode: arduino-pwm-frequency-library.

This is the tale of what happened.
