| Abstract: | In MPU control system and embedded system,it had a very higher request on real-time capability,along with the expansion of peripheral number and the system scale.To solve the problem and prevent MPU wasting it＇s time and space,it took system programming mode into consideration.Under the use of MPU uart communication module,it put forward a control mechanism based on the finite state machine controlled system,establish a state chart,explain and verify the absolute superiority in which the finite state machine was applied in the microcontroller programming. |
| Keywords: | finite state machine real-time system MPU state chart peripherals control |
