Conclusion
This application note has used the HT66F50 as the main control MCU to control the
HT16H25 for a treadmill display application. It has demonstrated the main features of the
HT16H25 as well as providing an application circuit and a sample program to help users
use the HT16H25's functions more flexibly.
