Design of Experimental Teaching Cases for"Electronic System Design"Course Based on SoPC
A SoPC was constructed using FPGA,and the uC/OS-II operating system was ported to achieve the hardware and software design of a small fan speed intelligent control system based on brushless DC motor;Using DS18B20 temperature sensor to collect ambient temperature and automatically control the motor speed based on the ambient temperature;By using the HC-SR04 ultrasonic module to measure the distance between objects,it has been achieved that when an object approaches the fan to a dis-tance of 8cm,the brushless DC motor automatically limits its speed and the buzzer sounds an alarm;The SU-03T speech recognition module was used to achieve voice control of motor speed;Through serial communication between FPGA and STM32F103C8T6 mi-crocontroller controlled Wi-Fi module,environmental temperature,fan speed,distance alarm signal,and motor rotation direction da-ta can be uploaded to Alibaba Cloud.
