This project started with STM32F1 and now it uses STM32F3.
The system uses TI's MSP430F149 microcontroller as the core controller. This microcontroller has a 16-bit CPU integrated register and constant generator, which can maximize the code efficiency of the microcontroller. It integrates JTAG and supports online programming; two universal full-duplex Serial synchronous/asynchronous communication interface; PWM control output; external interrupt input interface. The microcontroller is responsible for sampling the bus door opening and closing signals, turning on or off the infrared counting module, recording the number of people getting on and off at each bus stop, storing the data on the number of people getting on and off at each bus stop, and transmitting the stored data to the computer.
