[PIC] Supervisory Control for a Intelligent Battery Charger

Hi guys,

I need help with a project I am doing.
I am designing a battery charger that will allow me to control the charging current of a dedicated battery charger IC that is connected to a PIC18F4431. Is there anyone who knows how to go about doing it?

you can use a device such as the ACS712 to measure the current
**broken link removed**
feed its output into a PIC18 ADC.
Use PWM to control the current?

BQ2031 is also battery charging IC which can help you. wich gives intreface with controller too.

I am currently tied down to the MAX846A battery charger IC. is there any forum or whatsoever not that can provided me with reference C codes to write the program as I would admit that I am not very well verse with C code programming

Thats the general idea that was given to me as well. but I could do with some practical examples as I am really clueless as to how to go about starting the programming.
