Re: Wipy no float and math!

First, thanks for the pointers on what needs to be done to build with float support. That said, it isn't so simple. I understand why it was omitted. that is possible to make fw with working floating and math.. And no need reinvent crutches for floating values.. And no official info about how compile...

What do you _need_ floating point for?

Reconsider how you implement things for microcontrollers.

Floating point is generally overkill for most all applications. Merely a convenience that desktop computer users have become used to.

when will expansion board charge a battery?

Good: When i'm powering a wipy on the expansion board via usb, the lipo battery charging appears to work. Bad: When i plug 5VDC directly into the gnd + vin pins instead of connecting USB, the battery charger doesn't appear to do its thing. in fact it's a bit scary: from machine import ADC adc = ADC(...
