micropython only support UTF-8 code,I need to support chinese,so I add a font chip。but font chip only provide a *.a file and a *.h file,How should I use the two file?
You need to compile the firmware: openmv/src at master · openmv/openmv · GitHub
Which directory should *.a file and a *.h put in？
You have to write code to use the library and edit the build system.
is there an example？
No, you are asking questions about modifying the firmware and how to compile in a library. This is standard C coding that you can learn by googling how to do this…
OK，I will do it！
