arduino based firmware for the imax b6 charger the code is made very simple and can be modied to your needs
the imax b6 is a atmega32a based battery charger.
- smps buck boost converter , controlled fully by the arduino
- 6 channel balancer
- current / voltage meters
- 2x16 lcd display and 4 buttons

USE CTRL-SHIFT-U to upload the codes ... the UPLOAD BUTTON WILL NOT WORK !!!
THINGS THAT WORK
- lcd display
- buck converter !
- current limiter
- stage logic
- the logic to charge lifepo4 batteries
- balancer logic
- MULTIPLEXER reading the cells voltages
- some basic functions to the buttons
TODO
- boost converter
- boost charger signal ( all cells < 3.5V )
- battery ok signal ( all cells > 3.0V )
