automation project #20

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.
I'm on an automation project by the shield SMS GSM / GPRS at OPEN ELECTRONICS 
mounted on an Arduino

 I control a pump via SMS

 Here is the code

see GSM_AUTO_PUMP.ino

no problem I send SMS Pompeon the LED lights and the LED turns off Pompeoff
 I add a control valve

see GSM_AUTO_PUMP_VALVE.ino

I copy / paste I change the variables and nothing works

Now  Arduino no start 

What is the expected output? What do you see instead?

With the code for the valve, the arduino no start no message on serial monitor.

What version of the product are you using? On what operating system?

I'm using the latest version of  shield GSM libraries and Arduino 1.0

Please provide any additional information below.

 Thank you in advance

Hi, sorry but where is the difference between the two codes? Seems they are the 
same code. Marco

Hi 
Exactly, this is a mistake, sorry
I will change the first upload
But the problem is on the code GSM_AUTO_PUMP_VALVE. If I add 2 conditions for 
the valve in the code GSM_AUTO_PUMP

      if (memcmp(smsbuffer,vanne_on,7)==0) 
        {
          Serial.println("VANNE ON");
          digitalWrite(12, HIGH); 
        }
        if (memcmp(smsbuffer,vanne_off,7)==0) 
        {
          Serial.println("VANNE OFF");
          digitalWrite(12, LOW); 
        }

 I upload the new code in Arduino. And the Arduino no start. I delete the code and now the Arduino start.
It's really strange. I don't see the reason
If you have a idea why ?
Thanks in advance

I think that this can be a memory's problem. Do you have the DEBUG turned off 
(it takes a lot of ram)? Try reducing SMS buffer and let me know ;)

Hi all,

may be this will help:

i used Uno. after i changed mega, working fine. 
  and also for sting variable(Serial print) i used flash memory. i attached flash library. may be it will reduce the usage of ram.
    the library taking 8K to 10K of memory and lot of internal variables. i am trying to reduce usage of variables. 

    My suggestion is,

 use flash library and add like this for sting.
        For example 
             _cell << "AT+CMGL=\"REC UNREAD\",1" << endl;
             _cell << F("AT+CMGL=\"REC UNREAD\",1") << endl;
  it will reduce usage of ram.

You're right next step will be this. Did you use software or hardware serial 
for mega?

i have the same problem how to debug turn off?

Original comment by veezo201...@gmail.com on 2 May 2012 at 10:06

GoogleCodeExporter commented 8 years ago 
Which problem do you have?
To turn off the debug mode, open GSM.h and comment the line #define DEBUG_ON

sir i was trying to build same project to turn on led through sms then i have 
uploaded this code that i have attached down there after that i modified some 
code, now whenever i upload new code same mesage keep repeating its self i dont 
know something like this.....i need help please its my final year project i m 
trying since  morning i dont know how to get rid of this problem

Because each time it reads the message in the buffer.

GoogleCodeExporter commented 8 years ago 
so how to get rid if this ?

Original comment by veezo201...@gmail.com on 2 May 2012 at 10:38

GoogleCodeExporter commented 8 years ago 
Or you delete it after you read it with sms.DeleteSMS(byte position) (you have 
to include an sms object, see SMS example)or modify line 142 in SIM900.cpp
from 

  SimpleWriteln("AT+CMGL=\"REC UNREAD\",1");

to

  SimpleWriteln("AT+CMGL=\"REC UNREAD\",0");

it should work.

Let me know, Marco

Hi all
Thank you very much, Martines, the line of code "SimpleWriteln("AT+CMGL=\"REC 
UNREAD\",0");" has resolved one by problems.

I have rewrited the code and I use "#ifdef..#endif" for no compiled the code 
for debug.
two level 
#define DEBUG_CODE_ON for to see the initialisation sequence.
#define DEBUG_ACTION_ON  for to see the action with a sms

If define DEBUG_CODE_ON and DEBUG_ACTION_ON  the 
after verify I have
"Binary sketch size: 10448 bytes (of a 32256 byte maximum)"
If no define DEBUG_CODE_ON and DEBUG_ACTION_ON  the 
after verify I have
"Binary sketch size: 10050 bytes (of a 32256 byte maximum)"

the code in Arduino works correctly. I send a SMS "Pompeon" the led  attached 
at the pin 13 is on and after a SMS "Pompeoff" the led is off.

With no define DEBUG_CODE_ON and DEBUG_ACTION_ON and
if I open the code for valve
after verify I have
"Binary sketch size: 10428 bytes (of a 32256 byte maximum)"
this is lower with debug on.
but the arduino is stop ..no start.

I think that this is a problem of memory.

I have several tracks and several questions
Can I reduce the buffer of SMS (160bytes) ?
Can I use the flash RAM ?
Can I use  a link with  a other Arduino cart ?

Thanks in advance
Sorry, I m french and my English is not very well.

I'm happy that it worked :)
For the memory problem, pay attention that your're watching the FLASH memory 
not the RAM memory. The flash is dedicated to store the sketch (sequence of 
istructions) but the problem is the RAM for string, int, ecc...
for example:
if you define in your sketch
int test[999];
int test2[999];
int test3[999];
int test4[9999];

these are very few instructions, so not many bytes for the sketch (that you can 
read after verifying it) but a lot of RAM and arduino doesn't work. 
Unfortunately there is no way to know (for my knowledge) how many RAM have you 
used. However above there is the trick of sjkr06 (that i haven't tried for now) 
for reduce RAM usage.
