A hardware approach would be to include a specific module (like this one for example), provided there's space for it in the increasingly crowded case (after including also the modules for battery charging, step up converter, serial to USB...).vcpinto wrote:Hi,
How do you know when the battery is low?
Has anyone made a circuit to show the battery level?
Possibly, the most elegant way to do it would be a firmware mod to use one of the free AD converters in the MCU to read battery voltage and show a battery level icon on the screen... maybe Jyetech could have this into account for the next FW release; it'd still be better if he included the battery charging and boost circuitry in a future new HW revision! (or, for the cost concerned, include in the PCB the circuitry for battery support and leave it as an option, where you could buy the kit with or without the extra needed components).
