Problem with atlas stamps ph v5.0 [SOLVED]

[Ricard Fraidias]

Hello colleagues recently talking about problems with fernando ph readings in my driver .. after several hours lost .. I commented my problem ... some more user has in his hands a stamp ph v5.0?
the problem is this .. to send the temperature value to compensate ph reading. the stamp does not return the value of ph. in the manuals insist that function works that way.
Any user with any stamp v5.0 could confirm me? I have 3 units of v5.0 and have the same problem. We also have a stamp v.3.4 and working properly. someone could confirm that the same problem will happen?

Hi Richard,

unfortunately I don't have a stamp to test, but it could be useful to have a link of your stamp v5.0 and a link of your working stamp. Maybe comparing the two datasheets we can find some useful informations.

hello again. I just received high response cientific about the problem with v.5.0 stamps as friend fernando detect the problem of temperature compensation costs. atlas for just answered me that they have reprogrammed the module and this function has been removed. that if we send temperature compensated reading but not automatically returns the value ..
All in the code we will have to suffer some ferduino adaptation to this change with the modules v.5.0

Hi!

The solution to this problem is simple.

In the tab Stamps after:

Code: Select all

    Open_channel(ph1);
    Serial3.print(tempC);
    Serial3.print('\r');
    delay(500);


And:

Code: Select all

    Open_channel(ph2);
    Serial3.print(tempC);
    Serial3.print('\r');
    delay(500);


Add:

Code: Select all

   Serial3.print("r");
   Serial3.print('\r');
   delay(500);


Best regards.
