This project uses STM32 to drive a servo motor and fingerprint recognition module AS608 to achieve the application of mechanical switches. For code simplicity, only the fingerprint recognition function was used, and not all features were implemented. The upper-level machine program is used to enter fingerprints, which is convenient and user-friendly and also reduces the amount of code. Instructions for using the upper-level machine program are also provided in the user manual. The used servo is MG995, everyone can also choose according to their actual situation; the control principle for servos is basically the same, we can use the general or advanced TIM timers on STM32 (basic timers can only achieve counting function) to output PWM signals to control the servo. The servo motor needs to operate within a PWM signal with a period of 20 ms. By controlling the duty cycle of the PWM signal, the high-level time of the PWM wave is changed, thereby achieving control over the servo motor. For the MG995 servo motor, which rotates 180 degrees, the relationship between the PWM signal high-level time and the angle of rotation is as follows: 0.5 ms ——— 0 degrees; 1.0 ms —— 45 degrees; 1.5 ms —— 90 degrees; 2.0 ms ——— 135 degrees; 2.5 ms ——— 180 degrees; During the use, we judge the return data packet of AS608 using STM32. If the fingerprint matching is successful, we control the servo to rotate, achieving the effect of unlocking. This project is very suitable for beginners in embedded systems to learn how to use it. During the process, one can practice controlling STM32 serial ports and TIM timers, as well as knowledge of power management. Please provide the content you would like translated to English.

The RX and TX pins of the STM32F103C8T6 are PA9 and PA10, respectively. The STM32F103C8T6 is a commonly used microcontroller in the STM32 series. Its pin distribution is as follows: PA9: USART1_TX, PA10: USART1_RX, PA2: USART2_TX, PA3: USART2_RX, PB10: USART3_TX, PB11: USART3_RX. Among them, USART1, USART2, and USART3 are the serial port modules on the STM32F103C8T6. You can choose the TX and RX pins of one of these serial port modules to connect to the corresponding pins of the Baidu Rongchuang Intelligent Voice Module to achieve control and communication. The specific choice of which pin depends on your design requirements and available pin resources. Where are the RX and TX pins of STM32F103C8T6? STM32F103C8T6 is a microcontroller with an ARM Cortex-M3 core, and its RX and TX pins vary depending on the communication interface. For example, if you want to use USART1 as the serial communication interface, then the RX pin is PA10 and the TX pin is PA9; if you want to use USART2 as the serial communication interface, then the RX pin is PA3 and the TX pin is PA2. It should be noted that if you want to use a certain pin as the RX or TX pin for UART communication, you need to first configure the pin to the corresponding function mode and enable the relevant peripheral clock. For specific pin allocation and configuration methods, please refer to the datasheet of STM32F103C8T6. Please provide the content you would like translated into English.
