Also, after a little searching I cannot seem to find find low cost rotary encoders. I know that the AustriaMicrosystems AS5040 IC has been mentioned in this forum, but I’d like to see a complete encoder (with shaft coupling) based on this chip.
Anyway, just thought I’d throw this in to see if there’s any interest in this area.
I have made my own rotary / optical encoder solution based on Attiny2313 chip already… Just have to finish the prototype and the firmware for connecting it to the controller that drives the h-bridge you mention above!
Thanks very much for replying to my post and pointing out more of your excellent work - I actually didn’t spot this on the x-sim forums.
I thought I’d post your board’s URL here in the hope that it might ‘Spark’ some interest. Seems that motor is not a major interest for people though.
Very fast ATtiny indeed! Nice work, and great to see that you are looking at encoding options also. I tried an ATmega32 with a standard rotary encoder and it seemed to work OK.
Hoping not to offend the fine Sparky people by turning this into another chat site maybe I could just mention that playing with Eagle I found this chip in the parts library by Agilent , a HCTL-1000 motor controller chip.
Not sure if it would be useful yet though…
I’m hoping you go ‘commercial’ with your controller boards in the future,
maybe even with Sparkies.
Cheers, Phil.

Hi,
I just seen this, so it might be some outdated…
