This project designs a wireless multi-functional seat indication system suitable for various occasions. It uses MSP430 microcontroller as the core, CC2500 transceiver as the radio frequency module, and uses the Simplici TI wireless communication protocol to form a small radio frequency network. As the master control platform (host computer), the PC transmits control commands to the MSP430 main controller (aggregation point AP) through the serial interface. The aggregation point AP completes data processing and wireless transmission, and transmits the data to each branch through wireless transmission. Controller (node ED), the ED node completes the display of information on the LCD and LED dot matrix screens.
