总结This experiment realizes the control of the given signal frequency and duty cycle by means of the control button During the experiment key 1 and key 2 should be used to adjust the signal frequency a

In summary, this experiment focuses on the control of signal frequency and duty cycle using control buttons. Key 1 and key 2 are used to adjust the signal frequency, while key 3 and key 4 are used to adjust the duty cycle. The frequency range is between 10Hz and 100Hz, with 10Hz intervals, and the duty cycle ranges from 1% to 100%, with 1% intervals.

To ensure a valid signal, the serial port needs to be identified and initialized before entering the main function. The RB port is used to determine the command requirements by jumping from 1 to 0 after pressing a key. The output signal is displayed on the oscilloscope, while the frequency and duty cycle data are displayed on the digital tube for feedback.

The experiment highlights the importance of using specially designed hardware devices and interfaces to control frequency and duty cycle. It also mentions the role of computer science in signal processing, especially with the development of embedded systems and technologies like DSP. Furthermore, the emergence of AI technologies like NLP and computer vision provide new ideas and solutions for signal processing and control systems.

In conclusion, signal processing is a significant field that has brought significant changes and influences in practical applications. By utilizing relevant technologies and equipment, we can accurately control signal frequency and duty cycle, leading to improvements and optimizations in embedded systems. This lays a solid foundation for future scientific development and industrial production
