    1, Work on the MSP432 LaunchPad standalone and familiarize with its software development. Don’t plug the Launchpad onto the Alice EduPad until you feel comfortable in writing a small test program because it’s easier to test a small program on the Launchpad alone.

    Chapter 4: Hardware Descriptions The circuit is designed in such way that the value of all resistors and capacitors are not critical. 4.1 LEDs: The P3.2, P3.3, P2.5, P2.4 are connected to the LED0-LED3 via a buffer (U8). In order to turn on an LED, you need to program the corresponding pin as output and set it high.

  • Page 9: 7-Segment Led Display

    4.9 7-Segment LED display The type of the 7-segment LED display on the Alice EduPad is called common anode, all cathodes are driven individually by an output pin and the anode is connected to the 5V supply. Before sending a number to a 7-segment LED display, the number must be converted to its corresponding 7-segment code depending on how the 7-segment display is connected to an output port.

    4.10.2. Parallel interface LCD: (the jumper is placed on the 2 left-hand pins of J23) The Alice EduPad also incorporates a parallel interface for the LCD, the P3.6, P5.2, P5.0 and P4.6 are connected to the D4-D7 of the LCD via a 74HCT245 buffer (U18). The control pins are P3.0 for LCD R/S and P6.7 for LCD EN.

  • Page 11: H-Bridge

    4.12 H-Bridge The H-bridge driver TB6612FNG is similar to the SN754410N, but has MOSFET output. It’s much more efficient than the SN754410N, especially for controlling low voltage motors. The control software is the same for both IC’s. It can control two DC motors or one stepper motor. It takes two pins, P3.2 and P3.3, to control motor direction, one must be set at high, and the other one must be set at low.
