hi 12864L LCD sample source is being applied.

I want to change to hal lib because the old source has already been created.

Help!

It's just GPIO manipulation. It should be easy to replace the SPL functions with their Cube/HAL counterparts.

The original author may be available to provide some support in case of problems, try to contact him.
