Hi,
I am making a new design with CR2032 battery(about 3V) that uses MSP430F5308 which has ADC (and much more) and I would like to understand what is requied in terms of hardware and Firmware in order to check if battery level is lower then 2.5V (or better 2.7V)
I understand from several posts that it is possible to measure battery level (VCC) by comparing some internal reference (2.5v or 1.5V), my questions are:
1) Is there some reference code that I can use for this?
2) Does the hardware need to take this into account? or this is all internal firmware code only ?
Thanks
