menu question

[rossbryant1956]

I am learning menus and need to understand how to place decimal in the following code line:

Code: Select all

// pH Expansion
  ReefAngel.LCD.DrawText( COLOR_MEDIUMSEAGREEN,DefaultBGColor,15,75, "GT pH:" );
  ReefAngel.LCD.DrawText( COLOR_MEDIUMSEAGREEN,DefaultBGColor,39,75, ReefAngel.Params.PHExp );
  pingSerial();

It is displaying:

GT pH: 805

Needs to be:

8.05

Thx

You must use the ConvertNumToString function to accomplish this task. Check out the tutorial here:http://forum.reefangel.com/viewtopic.php?f=14&t=109
That will explain it (or show an example of it) on page 18.

Here is your example:

Code: Select all

// pH Expansion
ReefAngel.LCD.DrawText( COLOR_MEDIUMSEAGREEN,DefaultBGColor,15,75, "GT pH:" );
char text[7];
ConvertNumToString(text, ReefAngel.Params.PHExp, 100);
ReefAngel.LCD.DrawText(COLOR_MEDIUMSEAGREEN, DefaultBGColor, 39, 75, text);

The function ConvertNumToString will format the value with the appropriate decimal place.

Why aren't you using the DrawSingleMonitor function for the temperature?

I was wondering too lol

actually I was just showing the board the snippet I was having a problem with. I am using this snippet for my top menus's and I don't like it:

Code: Select all

int x,y;
  // Parameters
#if defined DisplayLEDPWM && ! defined RemoveAllLights
  ReefAngel.LCD.DrawMonitor( 15, 40, ReefAngel.Params,
  ReefAngel.PWM.GetDaylightValue(), ReefAngel.PWM.GetActinicValue() );
#else // defined DisplayLEDPWM && ! defined RemoveAllLights
  ReefAngel.LCD.DrawMonitor( 15, 40, ReefAngel.Params );
#endif // defined DisplayLEDPWM && ! defined RemoveAllLights
  pingSerial();

I will be switching over to DrawSingleMonitor function in the next day or so. Thx
