Based on MSP430-FFTB6638 Experiment Box

The frequency measurement and communication system uses the MCU timer module related functions to realize the digital frequency meter function, with a measurement range of 100~10000Hz, a measurement error of ≤1%, and a measurement speed of ≤1 second. The measurement results are displayed locally (segment LCD, character LCD, dot matrix LCD (128x64), dot matrix LED (16x16) or multi-digit 7-segment LED, etc.), and the measurement results are transmitted to other terminals such as PC/tablet/mobile phone through UART/RS232 communication.

Basic requirements for project design (must be done):
(1) Local display of information such as project name, student ID, name, measurement results, etc. (segment LCD, character LCD, dot matrix LCD (128x64), dot matrix LED (16x16) or multi-digit 7-segment LED, etc.).
(2) Project name, student ID, name, measurement results and other information are transmitted to other terminals such as PC/tablet/mobile phone through UART/RS232 handshake communication (the handshake signal is the student ID or student ID).
(3) The buzzer sounds to indicate the start of a function or different buzzer sounds indicate different working states, such as whether the communication handshake is correct or not.
Project design improvement requirements (optional):
(1) Use buttons or serial port commands to switch between different functions.
(2) The project name, name and other information are displayed in Chinese.
