Just assembled Bittle to the point of getting the software going.
Battery reads 8.25 volts with a volt meter and has a blue light on when active. Can disconnect USB and Bittle stays powered up, but OpenCat keeps returning "Low power!". Using the latest version of everything from github.
I modified the code to report the voltage. It is returning around 360 as the voltage each time through the loop.
I set the LOW_BATT to 1 just to see what happens and it allows the calibration, though I only did if for a few seconds in case I was going to hurt something and it really is low voltage.
I am not sure which version of the board I have, so I have tried it using version 1 and 2 with the same result.
Any ideas? I will try any possible solution.
Thanks.
