For this assignment, reference the following articles :

• 2012 SJ One Hello World Sample Project
• Board Documentation

Assignment

1. If Switch #1 is pressed, light up LED #1, else turn LED #1 off
2. If Switch #2 is pressed, display Light Sensor value on 7-Segment LED Display
   • Note that maximum light sensor value is 4096, calculate the percent first, then display on LED Display
3. If Switch #3 is pressed, display temperature in Fahrenheit on 7-Segment LED Display
4. If Switch #4 is pressed, display Acceleration Sensor's X-Axis on 7-Segment LED Display
   • Note that minimum value is -1024 and maximum value is +1024.
   • You can add 1024 to this value, then calculate percentage by ((X-Axis+1024)/ 2048) * 100
5. The points for this assignment depends on how much you add to the program. For example, you can take advantage of the acceleration sensor's Y and Z axis and make the board more interactive. If you have a remote control with you, you can even take advantage of reading IR code received by the board, and light up some LEDs.

Sample Code

#include <stdio.h>
#include "utilities.h"  // delay_ms()
#include "io.hpp"       // board IO

int main(void)
{
    // Just by typing Board IOname, such as : "AS"
    // should give you functions you can invoke of Acceleration Sensor
    // See the reference assignment link above.
    // Also open up io.hpp to get list of names of Board IO
    while(1)
    {
        // Get the value of the switch by using SW object
        bool switch_one = SW.getSwitch(1);

        // Light up an LED by using LE object
        if(switch_one) {
            LE.on(1);
        }

        // Get temperature using TS object
        int temperature = TS.getCelsius();

        // Display on LED display using LD object
        LD.setNumber(temperature);

        // Read the documentation to complete the rest of the assignment.
    }

    return 0;
}
