Issue : Adding additional code to Void Loop .....

system · July 9, 2013, 2:29pm

Hi,
I’ve been working on the following code for several weeks now as a first project.
Everything is working out slowely, but when i added a new peice of code to the void loop to add temperature probe then the touch screen buttons no longer work .
Im guessing for some reason its not going back to the top of the loop, :S…
im a newbie at this so the code below im sure is not tidy or well written.
Any changes or help would be appreciated.

#include <UTFT.h>
#include <UTouch.h>
#include <DS1307.h>
#include <Servo.h>

/*************************
**   New Code for Temp   **

#include <OneWire.h>
#define RELAY_PIN 3
#define RELAY_PIN1 6
#define ledPin2 5
#define ledPin3 4


// Init the DS1307
DS1307 rtc(20, 21);

OneWire  ds(10);  // on pin 10 (a 4.7K resistor is necessary)



// Declare which fonts we will be using
extern uint8_t SmallFont[];
extern uint8_t BigFont[];


UTFT        myGLCD(ITDB32S, 38,39,40,41);   // Remember to change the model parameter to suit your display module!
UTouch      myTouch(6,5,4,3,2);

int x, y;
char stCurrent[20]="";
int stCurrentLen=0;
char stLast[20]="";
int ledPin =  13;
int relayPin1 = 8; // for SKIMMER
int relayPin2 = 9; // for PUMP
int relayPin3 = 11; // for EXT FILTER
int reset = 30; // reset Button

int ledPin1 = 2;  // LED Blue for Cold
//int ledPin2 = 5; // LED RED for HOT
//int ledPin3 = 4; // LED Green for Normal
int fanPin1 = A1; //Fan pin

long num;

char num1;

float tempW = 0;

First, there is no such thing as "the void loop". There is a function called loop. The loop function has a void return type. Secondly, If your code is too big to put in a single post, use the "Additional Options" link to attach it. Lastly, pretend like we don't know anything about your project and give a more details of what you are expecting your code to do, and what it is actually doing.

HazardsMind · July 9, 2013, 2:50pm

You need to see exactly where the code is staying at by using the serial monitor if possible. OR use your own screen to display a simple number in the corner of the screen, to tell you where your code is at.

If the numbers continue to loop at a certain spot, then you'll know where the code is getting hung up, and probably why your buttons are not working.

system · July 9, 2013, 2:52pm

the code is for an aquarium controller.
i have the following attached to the arduino
1: RTC clock
2: temp prob
3: 6 relays.

what ive achieved so far is ive drawn the buttons on the UTFT, and 3 of them control the relays.
got time and date to display on the screen

what im trying to get now is the temperature to display on the screen, and with the code i added the temperature shows ont he screen but then the touch screen buttons no longer function.
When i press the on , the On goes green and increases in size which no longer works after adding the temperature code into the end of the code.
Here is a pic of the code running atm

You should consider putting constant strings Serial.print ("xyz"); in program memory using the "F()" macro Serial.print (F("xyz"));

system · July 9, 2013, 2:54pm

thanks for that suggestion HazardsMinds, ive never actually thought of using the serial.print to track the code. Will give it a shot.

system · July 9, 2013, 2:57pm

, ive never actually thought of using the serial.print to track the code.

But if you're running short of RAM, it can make the problem worse.
Make sure you use the F() macro.

mmcp42 · July 9, 2013, 2:59pm

I may be wrong but you have lots of

return;

in your code
that will cause immediate exit of

loop()

system · July 9, 2013, 3:59pm

I tried as hazard suggested by putting in Serialprintln at the start, mid and end of code.
I see it is looping around , the temp code i added must be somehow causing a conflict with the touch buttons…

i’ll keep staring at the code to see if i can see what could be causing the issue.
If anyone can notice why this could be happening , would be great.

Anarkie:

During your delays, nothing else will happen (like the touch buttons being read). To get round this, look up 'blink without delay' in the playground.

Get rid of all the delays first!
