### A short guide to use fontconvert.c to create your own fonts using MinGW.
|
||
|
|
|
||
|
|
#### STEP 1: INSTALL MinGW
|
||
|
|
|
||
|
|
Install MinGW (Minimalist GNU for Windows) from [MinGW.org](http://www.mingw.org/).
|
||
|
|
Please read carefully the instructions found on [Getting started page](http://www.mingw.org/wiki/Getting_Started).
|
||
|
|
I suggest installing with the "Graphical User Interface Installer".
|
||
|
|
To complete your initial installation you should further install some "packages".
|
||
|
|
For our purpose you should only install the "Basic Setup" packages.
|
||
|
|
To do that:
|
||
|
|
|
||
|
|
1. Open the MinGW Installation Manager
|
||
|
|
2. From the left panel click "Basic Setup".
|
||
|
|
3. On the right panel choose "mingw32-base", "mingw-gcc-g++", "mingw-gcc-objc" and "msys-base"
|
||
|
|
and click "Mark for installation"
|
||
|
|
4. From the Menu click "Installation" and then "Apply changes". In the pop-up window select "Apply".
|
||
|
|
|
||
|
|
|
||
|
|
#### STEP 2: INSTALL Freetype Library
|
||
|
|
|
||
|
|
To read about the freetype project visit [freetype.org](https://www.freetype.org/).
|
||
|
|
To Download the latest version of freetype go to [download page](http://download.savannah.gnu.org/releases/freetype/)
|
||
|
|
and choose "freetype-2.7.tar.gz" file (or a newer version if available).
|
||
|
|
To avoid long cd commands later in the command prompt, I suggest you unzip the file in the C:\ directory.
|
||
|
|
(I also renamed the folder to "ft27")
|
||
|
|
Before you build the library it's good to read these articles:
|
||
|
|
* [Using MSYS with MinGW](http://www.mingw.org/wiki/MSYS)
|
||
|
|
* [Installation and Use of Supplementary Libraries with MinGW](http://www.mingw.org/wiki/LibraryPathHOWTO)
|
||
|
|
* [Include Path](http://www.mingw.org/wiki/IncludePathHOWTO)
|
||
|
|
|
||
|
|
Inside the unzipped folder there is another folder named "docs". Open it and read the INSTALL.UNIX (using notepad).
|
||
|
|
Pay attention to paragraph 3 (Build and Install the Library). So, let's begin the installation.
|
||
|
|
To give the appropriate commands we will use the MSYS command prompt (not cmd.exe of windows) which is UNIX like.
|
||
|
|
Follow the path C:\MinGW\msys\1.0 and double click "msys.bat". The command prompt environment appears.
|
||
|
|
Enter "ft27" directory using the cd commands:
|
||
|
|
```
|
||
|
|
cd /c
|
||
|
|
cd ft27
|
||
|
|
```
|
||
|
|
|
||
|
|
and then type one by one the commands:
|
||
|
|
```
|
||
|
|
./configure --prefix=/mingw
|
||
|
|
make
|
||
|
|
make install
|
||
|
|
```
|
||
|
|
Once you're finished, go inside "C:\MinGW\include" and there should be a new folder named "freetype2".
|
||
|
|
That, hopefully, means that you have installed the library correctly !!
|
||
|
|
|
||
|
|
#### STEP 3: Build fontconvert.c
|
||
|
|
|
||
|
|
Before proceeding I suggest you make a copy of Adafruit_GFX_library folder in C:\ directory.
|
||
|
|
Then, inside "fontconvert" folder open the "makefile" with an editor ( I used notepad++).
|
||
|
|
Change the commands so in the end the program looks like :
|
||
|
|
```
|
||
|
|
all: fontconvert
|
||
|
|
|
||
|
|
CC = gcc
|
||
|
|
CFLAGS = -Wall -I c:/mingw/include/freetype2
|
||
|
|
LIBS = -lfreetype
|
||
|
|
|
||
|
|
fontconvert: fontconvert.c
|
||
|
|
$(CC) $(CFLAGS) $< $(LIBS) -o $@
|
||
|
|
|
||
|
|
clean:
|
||
|
|
rm -f fontconvert
|
||
|
|
```
|
||
|
|
Go back in the command prompt and with a cd command enter the fontconvert directory.
|
||
|
|
```
|
||
|
|
cd /c/adafruit_gfx_library\fontconvert
|
||
|
|
```
|
||
|
|
Give the command:
|
||
|
|
```
|
||
|
|
make
|
||
|
|
```
|
||
|
|
This command will, eventually, create a "fontconvert.exe" file inside fontconvert directory.
|
||
|
|
|
||
|
|
#### STEP 4: Create your own font header files
|
||
|
|
|
||
|
|
Now that you have an executable file, you can use it to create your own fonts to work with Adafruit GFX lib.
|
||
|
|
So, if we suppose that you already have a .ttf file with your favorite fonts, jump to the command prompt and type:
|
||
|
|
```
|
||
|
|
./fontconvert yourfonts.ttf 9 > yourfonts9pt7b.h
|
||
|
|
```
|
||
|
|
You can read more details at: [learn.adafruit](https://learn.adafruit.com/adafruit-gfx-graphics-library/using-fonts).
|
||
|
|
|
||
|
|
Taraaaaaammm !! you've just created your new font header file. Put it inside the "Fonts" folder, grab a cup of coffee
|
||
|
|
and start playing with your Arduino (or whatever else ....)+ display module project.
