My main concern is to connect the J2 connector(consisting of 1 to 7 pins from LTC4008) to a microcontroller to observe the charging status of each cell.
There is a very similar microcontroller unit which is ISL9208EVAL2Z, but this pcb only support up to 7 cell. And mine is 8 cells
I took a look at the appnote. The ISL9216 does have an I2C port, which several of the MCUs listed above have an I2C which will interface with the ISL9216 nicely.
It also supports connection with a PC via USB and control by a GUI application which would be the simplest way to utilize the ISL9216 board.
If you would still like to build a standalone battery charge with LCD screen it can be done.
Do you have any C language experience? Any programming language experience at all?
