2. Use the bdf-converter program to convert the BDF font to the NuttX
font format. This will result in a C header file containing
definitions. That header file should be installed at, for example,
graphics/nxfonts/nxfonts_myfont.h.

Create a new NuttX configuration variable. For example, suppose
you define the following variable: CONFIG_NXFONT_MYFONT. Then
