This project aims to teach you about the Serial Peripheral Interface (SPI) communication protocol and how to interface the TC72 temperature sensor with an STM32 microcontroller. The TC72 is a digital temperature sensor that can provide highly accurate temperature readings with low power consumption, making it ideal for use in a variety of embedded applications.
According to the datasheet for the TC72 sensor, in order to establish a connection between the sensor and a microcontroller, it is necessary to connect the SPI bus lines, specifically the SCLK, MOSI, and MISO lines, between the two devices. The chip select (CS) pin must also be utilized to enable and disable the sensor during communication.
After establishing the connections, you will need to configure the SPI settings on the microcontroller, including the clock frequency, data order, and data frame size. Once the settings are configured, the microcontroller can send commands to the TC72 sensor to request temperature data. The sensor responds by providing the temperature value in a 16-bit data frame.
The microcontroller will then receive the temperature data and perform any necessary calculations or conversions to display or use the temperature value. This process can be repeated as needed to continuously monitor the temperature using the TC72 sensor.
By following the step-by-step instructions provided in this project, you will learn how to configure the necessary settings, and develop code to read the temperature values from the sensor. this project will also include simulation on Proteus software.
Step One:- Open CubeMX & Create New Project Choose The Target MCU STM32F103C6 & Double-Click Its Name
