STM32F103读取DS18B20温度传感器数据
STM32F103与DS18B20温度传感器的集成应用
在现代嵌入式系统中，温度监测是一个至关重要的功能，尤其是在工业自动化、环境监测、智能家居等领域。STM32F103，作为一款高性能、低功耗的32位Flash微控制器，凭借其丰富的外设接口和强大的处理能力，成为了实现这一功能的理想选择。而DS18B20，作为一款常用的数字温度传感器，以其高精度、单线通信和宽温度范围（-55°C至+125°C）而受到广泛欢迎。
在STM32F103与DS18B20的集成应用中，STM32F103通过其GPIO端口与DS18B20进行通信。DS18B20采用独特的单线通信协议，这意味着它只需要一个数据线（通常是STM32F103的某个GPIO引脚）就能完成温度数据的读取。通过一系列特定的时序操作和指令，STM32F103可以触发DS18B20进行温度测量，并读取测量结果。
在实际应用中，首先需要对STM32F103和DS18B20进行初始化设置。这包括配置STM32F103的GPIO端口为开漏输出模式，并设置适当的时序参数。然后，STM32F103会发送一系列指令给DS18B20，包括开始转换命令
