基于stm32 TSIC506f带校验测温程序

以下是一个基于STM32的TSIC506F带校验的测温程序示例，使用了HAL库：

这个程序使用了STM32的HAL库，通过UART接收TSIC506F的温度数据，并进行校验。如果校验通过，则将温度数据输出到串口上。

需要注意的是，TSIC506F的数据帧中包含了起始字节、结束字节和校验位，需要进行相应的处理才能得到正确的温度数据。在这个程序中，如果收到起始字节0x02，则将接收到的数据存储到缓冲区中，并记录开始时间；如果在一定时间内没有收到完整的数据帧，则清空缓冲区。如果收到结束字节0x03，则将缓冲区中的数据解析成温度数据，并进行校验。如果校验通过，则将温度数据输出到串口上。
