anyone used a continuous rotation resistor for a dc motor for tracking position like this one from digikey: http://www.digikey.com/product-detail/en/3382G-1-103G/3382G-1-103GTR-ND/1944266 manufacturer is Bourns. I need to track rotation of motor, to linear motion, like a lead screw. motor is 6v, ~1500rpm. only need to track about 20 revolutions in either direction. anyone have any other cheap suggestions, that are relatively small in size.
Hey all, I'm completely stumped on a bug for my design day project. I've got a rotary encoder that is used to change a value on an LCD screen. The code works perfectly when the encoders state at power up is 00. However if either pin is high, it doesn't work at all. Some transitions will cause the value on the screen to move in the wrong direct, and some transitions don't seem to trigger an interrupt at all. This is the code I'm using and would LOVE some help! Is it possible that the MSP430 is recording the initial values as reference voltages causing subsequent interrupts to not work?
