    Has anyone tried to use a camera to make an absolute encoder. I was thinking of printing an encoder grey scale on a drum, then use the video out signal connected into a the RX pin on a micro UART. If the size of image and correct baud rate is selected you should get a good binary value for the current encoder location. The scale would have to have a start and stop bit added to the top and bottom.
    The 15khz vertical scan with 8 bit grey scale would be about 150k baud. The 1Vpp would also have to be amplified to 5V level. You could have 2 bytes of data printed on the drum and have 16bit position resolution!!

    I found that Phase = 1 and Pole = 1 works fine. I think the datasheet indicates that sample is on rising clk and clk is normally high.

No public wish lists :(
