| Abstract: | In order to satisfy the need of monitoring and displaying the output voltage of multi-channel piezoelectric ceramics high-voltage actuators in the adaptive optics system,a voltage monitoring,displaying and communication system was designed based on high-speed MCU-C8051F120.The voltage data was acquired by 20-channel voltage measurement module,and the data was received,processed and displayed through ModBus RTU protocol.Then this paper presented the LCD interface hardware design,the communication between MCU and voltage measurement module and the software design.Finally,the result of experiments shows the good effects of the system design. |
