采用DS18B20和STM32F103RBT6编写的测温程序，每秒从USART1输出温度数据。采用3.5版固件库，自编DS18B20库文件，需要注意的是使用本库前需要写delay_us和delay_ms函数。电路上采用8M晶振，PA8为数据口，如有变化请修改stm32f10x_conf.h文件。-The temperature program DS18B20 and STM32F103RBT6-written per second from USART1 output temperature data. The version 3.5 firmware library, composing the the DS18B20 libraries should be noted that before using the library need to to write delay_us and delay_ms function. 8M crystal oscillator circuit, PA8 data port, if the changes please modify the stm32f10x_conf.h file.
