Finally, we need to extend the logic that does the run-time font lookups so that can find our new font.
|
||||
The lookup function is <code>NXHANDLE nxf_getfonthandle(enum nx_fontid_e fontid)</code>.
|
||||
The lookup function is <a href="#nxfgetfonthandle"><code>NXHANDLE nxf_getfonthandle(enum nx_fontid_e fontid)</code></a>.
|
||||
Note that the lookup is based on the font ID that was defined in step 4.
|
||||
The new font information needs to be added to data structures used by that function:

nsh> msdis # Disconnect USB storate device

nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Restore the mount
