Scroll pHAT HD に美咲フォント
0 likes1,882 views
The document discusses converting a Japanese font file into a format that can be displayed on the Scroll pHAT HD. It involves taking a BDF font file with JIS X 0208 character encodings, running it through a Perl script to convert the encodings to Unicode, and outputting it as a Python data structure that can be loaded and used by the Scroll pHAT HD library. An example Python script is provided that loads the converted font file and displays Japanese text on startup.
