This Concept Map, created with IHMC CmapTools, has information related to: USBIO24R and Printer Motor and Position marker, The Larger Picture drive 1 motor Have decided to make the first board control 1 motor only, and concentrate on developing the software., The old printer parts Consists of a small 5V motor, gears, rubber bands, plastic engraved position ring, and a light interrupter device. ???? The Motor Two white wires power the motor. By trial and error, 5V powers the motor well. Polarity for CW and CCW rotation is shown in the attached jpeg images., motor and position ring The old printer parts Consists of a small 5V motor, gears, rubber bands, plastic engraved position ring, and a light interrupter device., Objectives I want to be able to rotate the motor a given angle, either CW or CCW, using the USBIO24R class interface. output The number of lines counted. There are no interupt lines, so will have to poll the input lines to determine if a line should be counted. If the motor speed is too fast, you could miss a line ! Not a great strategy., Programming a motor and position reader off an old printer, using the USB IO24R from Elexol. why ? Objectives I want to be able to rotate the motor a given angle, either CW or CCW, using the USBIO24R class interface., The old printer parts Consists of a small 5V motor, gears, rubber bands, plastic engraved position ring, and a light interrupter device. ???? The Position Ring Has engraved lines around the perimeter. Associated is an IR T/R photo device that signals if a line, or no-line is under the beam. There are 5 lines connecting to this device., motor and position ring Programming a motor and position reader off an old printer, using the USB IO24R from Elexol., Programming a motor and position reader off an old printer, using the USB IO24R from Elexol. ????
