M52259 TOWER - TFT display and Temperature/humidity sensor

[jezc]

Hi Mark,

I've just tried to build the simulator version without the GLCD support (commented out '#define SUPPORT_GLCD' in config.h) & it's failing to build -

1>Linking...
1>LCDSim.obj : error LNK2019: unresolved external symbol _fnPenMoved referenced in function "int __cdecl fnPenDown(int,int,int)" (?fnPenDown@@YAHHHH@Z)
1>LCDSim.obj : error LNK2019: unresolved external symbol _fnPenPressed referenced in function "int __cdecl fnPenDown(int,int,int)" (?fnPenDown@@YAHHHH@Z)

1>.\Debug/uTaskerV1-4.exe : fatal error LNK1120: 3 unresolved externals

Not a huge problem at present (while I'm running development code on the simulator), but I haven't got the LCD for the tower yet and I think you said it would hang if it's built into the code but not fitted?

Cheers,

Try a project clean and rebuild - these functions shouldn't be needed when there is no GLCD used and sometimes VS doesn't recompile all files after a change.

If it turns out to still be a problem remove SUPPORT_TOUCH_SCREEN from the hardware configuration file because this is specifically used for simulating the touchscreen operation.

Regards

Hi Mark,

Yes, doing the clean first has done the trick as you expected! I'd tried a rebuild all with no success, will have to make a note to do a clean every time I change a macro definition, just to be safe!

Thanks again for the excellent support!

Cheers,

Hi Jez,

I use the Luminary Micro Version of uTasker, and its my experience that VC does sometimes to recognise that a change in a header file means that it needs to recompile a cpp file. So if your change effects something in the simulator best to do a full build. Never have gotten to the bottom of this "feature".

Cheers

Hi Martin,

Thanks for the information/confirmation - I'll check with some of my colleagues if they have a similar problem with their native Visual Studio projects (though they're mostly using C# nowadays).

I'll also see if they can try the project with a 'full' version of Visual Studio (rather than express), just in case that's a factor too.

I'll let you know if I find anything more about this.

Cheers,

Hi Jez,

I use a full version of VC, and to clarify it seems like a change to a header file triggers dependant C files to be recompiled, but sometimes not C++ files (i.e. the simulator files). As an example if I have a GLCD emulated and then change its size and just try to run again, this change has not occurred in the simulator. A full compile fixes it.
