    Re: Display Degrees of rotation.

    I had thought about using a compass sensor. Still like the idea. Most I found were on the expensive side, not to mention I was just getting my feet wet messing with PICs and programming. Should I...

    Re: Display Degrees of rotation.

    I may have to consider that.
    I only have a hand drawn schematic.
    Here is a picture of the almost completed project. I still need to finish the labeling.

    Re: Display Degrees of rotation.

    Thanks for all the replys.
    I ended up using a hall sensor and the magnets from a CD drive motor for the sensor part. I used a 16F1827 PIC, a 2x16 LCD and other hardware. I now have a rotor...

    The pot is for the contrast, I have 3 pots on a separate board to control the RGB back light.
    The display DOES use the standard LCD controller, I made sure I at least got that part right.

    P16F1827 and LCD Problems

    I am new to all of this:
    I have triple checked my wiring to the PIC<16F1827> and LCD as follows:

    PIC LCD
    RB0 = D4
    RB1 = D5
    RB2 = D6
    RB3 = D7
    RB4 = RS
    RB5 = E

    Most that I have found DO NOT support the 16F1827. May have to find a more common chip.
    Better yet, guess I need to learn C

    I went with a P16F1827
    Has enough pins to do what I want. I also have MPLAB and a PICKIT3.
    Now to just figure out a simple code to make the 2x16 LCD say "Hello" in 4 bit mode.

    PIC and LCD Recomendations

    I need a pic to do the following:
    1) Drive a 2 line LCD.
    2) Be able to use the data stream from an optical encoder (from a mouse)
    3) Have at least 2 outputs that can via a transistor turn a...

    lessons learned

    Well I managed to make and fix a pulse disc to the back of the motor. The mouse encoder reads it, just not with any accuracy. Used the encoder from the mouse in my drill and it works fine.
