I want to make a Li-Po battery charger using the Fez Domino (or Panda) to charge an on-board battery. The theory is pretty well known…
My question is if I’m looking for trouble here. What are the things I should watch out for (other than the danger of an exploding battery).
To make it even more interesting, I’d like to charge a 8.4V battery from the Usb port. This means I have to make a boost converter as well. It seems doable with the PWM and A/D ports - but I don’t know if the sampling rate is quick enough for this kind of thing.
Anybody else tried this before in managed code?
Before you ask why I’m not using an off the shelf chip, two reasons:
- I looked at BQ24115 - and got samples. It is ridiculous to try and work with on a DIY PCB.
- The Panda has all the peripherals and theoretically I have the programming skill so why not?
