i want to stick to the bildr Tutorial http://bildr.org/2011/03/ds1307-arduino/
I want to put the very simple code in my mpr121 code, but it does never compile. The simple code is actually mostly the void loop, but i dont know how to put that into the other one.
I want to put this code:
//Arduino 1.0+ Only
//Arduino 1.0+ Only
#include "Wire.h"
#define DS1307_ADDRESS 0x68
void setup(){
Wire.begin();
Serial.begin(9600);
}
void loop(){
printDate();
delay(1000);
}
byte bcdToDec(byte val) {
// Convert binary coded decimal to normal decimal numbers
return ( (val/16*10) + (val%16) );
}
void printDate(){
// Reset the register pointer
Wire.beginTransmission(DS1307_ADDRESS);
byte zero = 0x00;
Wire.write(zero);
Wire.endTransmission();
Wire.requestFrom(DS1307_ADDRESS, 7);
int second = bcdToDec(Wire.read());
int minute = bcdToDec(Wire.read());
int hour = bcdToDec(Wire.read() & 0b111111); //24 hour time
int weekDay = bcdToDec(Wire.read()); //0-6 -> sunday - Saturday
int monthDay = bcdToDec(Wire.read());
int month = bcdToDec(Wire.read());
int year = bcdToDec(Wire.read());
//print the date EG 3/1/11 23:59:59
Serial.print(month);
Serial.print("/");
Serial.print(monthDay);
Serial.print("/");
Serial.print(year);
Serial.print(" ");
Serial.print(hour);
Serial.print(":");
Serial.print(minute);
Serial.print(":");
Serial.println(second);
}
into this one:
#include "mpr121.h"
#include <Wire.h>
int irqpin = 2; // Digital 2
boolean touchStates[12]; //to keep track of the previous touch states
void setup(){
pinMode(irqpin, INPUT);
digitalWrite(irqpin, HIGH); //enable pullup resistor
Serial.begin(9600);
Wire.begin();
mpr121_setup();
}
void loop(){
readTouchInputs();
}
void readTouchInputs(){
if(!checkInterrupt()){
//read the touch state from the MPR121
Wire.requestFrom(0x5A,2);
byte LSB = Wire.read();
byte MSB = Wire.read();
uint16_t touched = ((MSB << 8) | LSB); //16bits that make up the touch states
for (int i=0; i < 12; i++){ // Check what electrodes were pressed
if(touched & (1<<i)){
if(touchStates[i] == 0){
//pin i was just touched
Serial.print("pin ");
Serial.print(i);
Serial.println(" was just touched");
}else if(touchStates[i] == 1){
//pin i is still being touched
}
touchStates[i] = 1;
}else{
if(touchStates[i] == 1){
Serial.print("pin ");
Serial.print(i);
Serial.println(" is no longer being touched");
//pin i is no longer being touched
}
touchStates[i] = 0;
}
}
}
}
