TinyDuino Processors & TinyShields / Re: stepper motor + dual motor shield

« on: June 29, 2017, 06:52:13 PM »

Thanks for posting this, I was about to ask about this shield and stepper motors as I realised after purchasing the shield that the PWM is sent over I2C to control the output of the H-Bridge.  It seems to me you need to pulse each input in the expected sequence and the motor should step (in theory), not tried it yet.  It would seem that instead of relying on existing libraries, I'll have to come up with my own loop  (would it be possible to microstep do you think?)

For my application I want to use a stepper like an accurate pointer, like the hour hand on a clock, so I just need to move it to a pre-determined angle and then return to the starting point.  With no particular feedback I guess I'll just need to count the steps carefully.

TinyDuino Processors & TinyShields / Re: Battery charge status/power remaining

Thanks,  I'll give that a go, should give an indication of how charged the battery is at least I hope, I never know how long to leave it on charge.  If I output to a some stats I guess I could get a picture of the discharge rate and maybe graph a curve.

TinyDuino Processors & TinyShields / Battery charge status/power remaining

Apologies if this has been asked before, but is there any way to check the charge status (ie approximate charge level) and estimate how long the battery would last at the current rate of discharge in use?

New Product Ideas / Ribbon cable "bus"

« on: May 16, 2016, 07:07:44 AM »

I have an application that is height restrictive, and ideally I'd like to place several (not just two) tinyduinos next to each other.  Is it possible to have an intermediate ribbon connector board, so that the lines go through the middle boards, rather than just one at each end?  IE the boards are laid out in a bus  Can a shorter ribbon cable be obtained?
