Hi All,
I am just trying this out and having an issue with the Multi Function Shield, I have copied a tutorial to make a countdown timer using the following code and the top right corner of each segment remains permanently lit up, which makes reading the numbers difficult, can anyone help?
#include <TimerOne.h>
#include <Wire.h>
#include <MultiFuncShield.h>
enum CountDownModeValues
{
COUNTING_STOPPED,
COUNTING
};
byte countDownMode = COUNTING_STOPPED;
byte tenths = 0;
char seconds = 0;
char minutes = 0;
void setup() {
// put your setup code here, to run once:
Timer1.initialize();
MFS.initialize(&Timer1); // initialize multifunction shield library
MFS.write(0);
Serial.begin(9600);
}
void loop() {
// put your main code here, to run repeatedly:
byte btn = MFS.getButton();
switch (countDownMode)
{
case COUNTING_STOPPED:
if (btn == BUTTON_1_SHORT_RELEASE && (minutes + seconds) > 0)
{
// start the timer
countDownMode = COUNTING;
}
else if (btn == BUTTON_1_LONG_PRESSED)
{
// reset the timer
tenths = 0;
seconds = 0;
minutes = 0;
MFS.write(minutes*100 + seconds);
}
else if (btn == BUTTON_2_PRESSED || btn == BUTTON_2_LONG_PRESSED)
{
minutes++;
if (minutes > 60)
{
minutes = 0;
}
MFS.write(minutes*100 + seconds);
}
else if (btn == BUTTON_3_PRESSED || btn == BUTTON_3_LONG_PRESSED)
{
seconds += 10;
if (seconds >= 60)
{
seconds = 0;
}
MFS.write(minutes*100 + seconds);
}
break;
case COUNTING:
if (btn == BUTTON_1_SHORT_RELEASE || btn == BUTTON_1_LONG_RELEASE)
{
// stop the timer
countDownMode = COUNTING_STOPPED;
}
else
{
// continue counting down
tenths++;
if (tenths == 10)
{
tenths = 0;
seconds--;
if (seconds < 0 && minutes > 0)
{
seconds = 59;
minutes--;
}
if (minutes == 0 && seconds == 0)
{
// timer has reached 0, so sound the alarm
MFS.beep(50, 50, 3); // beep 3 times, 500 milliseconds on / 500 off
countDownMode = COUNTING_STOPPED;
}
MFS.write(minutes*100 + seconds);
}
delay(100);
}
break;
}
}
