Several errors using custom font

[Spomky]

Hi,

I created a custom font using the wiki page step by step tutorial. I have a .c file that contains my font, but when I try to use it, I have the following compilation errors:

• error: unknown type name 'tImage'

Any idea?

You have to include header file with structure's definition. There is a strange way of programming in Arduion's area...

Examples/_Energia_IDE/renderTextExample3/renderTextExample3.ino :

#include <SPI.h>
#include <RA8875.h>
#include "fonts/akashi_36.c"

RA8875.h: #include "_settings/font.h"

_settings/font.h: typedef struct ... tImage;

Thank you for the quick reply. I’ve already included these header files

#include <SPI.h>
#include <RA8875.h>
#include "gilles.c"

It works fine using the fonts in the fonts folder, but not with that one I created. gilles.c code is as follow:

I think this because you are trying compile font's source file itself. But content of this file compiled inside other file:

#include <SPI.h>
#include <RA8875.h>
#include "gilles.c"

This is a very common mistake in the world of Arduino: Problems with Bitmaps on TFT Display using GFX Library

OK, I will read this thread. I noticed that my file does not have any __PRGMTAG_ definition. I am wondering if I missed an option during the conversion of the font…

[riuson]

All options are applied when font converted with right template file.

[Spomky]

OK looks like the template was not correctly loaded (even if I quit and run the software again). Sorry for the noise. Compilation without any error now. Regards.
