Chipkit Max32 and Arduino Clock Shield

The next in our list of arduino shields that we will be testing with the Chipkit Max32 is known as the Clock shield or Tick tock shield

Here is a picture of this shield

Features

Battery Holder : Battery on the card to the real-time clock chip power supply , making the board can continue to power down timer ;
Buzzer : 5V DC buzzer , do alarm clock, key tone ;
Photoresistor : intensity of ambient light sensor ;
Thermistor: detecting environmental temperature ;
K1 ~ K3: SCM can be scanned directly touch of a button ;
U5: TM1636, namely, four 8-segment common anode LED Driver IC ;
U3: DS1307, namely, real-time clock chip ;
D1 ~ D4: blue, green , red, red , 3mm plug LED.
Digital tube: 4 8 segments of positive points with a digital clock , and the decimal point is not displayed , only for identification purposes direction .

Occupied Arduino pin Resources: 

Total occupied nine digital pins , two analog input pins, an I2C interface
D2: control blue LED1;
D3: Control the green LED2;
D4: Control the red LED3;
D5: Control the red LED4;
D7: connection TM1636 clock pin SCLK;
D8: TM1636 data connection pin DIO;
D9: control keys K1;
D10: control buttons K2;
D11: control buttons K3;
A0: poll readings from temperature sensor;
A1: poll readings from light sensor;
A4: connect the DS1307 I2C data pin SDA;
A5: connect the DS1307 I2C clock pin SCL

Code Examples

Flash LED

[codesyntax lang=”cpp”]

int led1 = 2;

// the setup routine runs once when you press reset:
void setup() 
{                
  // initialize the digital pin as an output.
  pinMode(led1, OUTPUT); 
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led1, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);               // wait for a second
  digitalWrite(led1, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);               // wait for a second
}

Knightrider LED effect

[codesyntax lang=”cpp”]

int pinArray[] = {2, 3, 4, 5};
int count = 0;
int timer = 100;

void setup()
{
  for (count=0;count<4;count++) 
  {
    pinMode(pinArray[count], OUTPUT);
  }
}

void loop() 
{
  for (count=0;count<4;count++) 
  {
   digitalWrite(pinArray[count], HIGH);
   delay(timer);
   digitalWrite(pinArray[count], LOW);
   delay(timer);
  }
  for (count=3;count>=0;count--) 
  {
   digitalWrite(pinArray[count], HIGH);
   delay(timer);
   digitalWrite(pinArray[count], LOW);
   delay(timer);
  }
}
