Motor Controller
2005-08-15 by Mike Perks
Hi,
I have finally finished the documentation for my dual motor controller. It has the following features:
You can find all the details on my project page including some sample code for BasicX microcontroller. This should be readily converted for AVRs or other processors.
Even if you don't plan to build this circuit, there may be some ideas here that are useful for your own project (such as current limiting or opto-isolation).

I have finally finished the documentation for my dual motor controller. It has the following features:
- Uses L6205 dual H-bridge driver that supports up to 2.8A and is in a 20 pin DIP package
- On-board regulators for 12V and 5V power supplies
- Driver logic for enable, sign/magnitude PWM and separate brake signal
- Current sensing and variable current limiting with interrupt signals back to uC
- Optional opto-isolation between motor and logic circuits
