My goal is to build a DIY servo controller with BeagleBone and a DC motor with integrated quadrature encoder. The TI eQEP hardware peripheral integrated into the BeagleBone processor can accurately decode quadrature encoded pulses. I am using the Linux kernel driver from Nathaniel Lewis….
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
