Libraries are powerful tools! If a device program is perfectly libraryed, it means: 1. All engineers spend minimal effort when porting or creating the device driver. 2. As the number of users increases, it becomes more stable through extensive testing, evolving into a well-deserved public code. 3. The external interface of the library (function names … Read more
