# NTC
- （可选）打开外部晶振
- 给PA4选择ADC1_IN4
- 进入ADC配置
- Enable Continuous Conversion Mode
- Rank - Sampling Time配置为239.5Cycles
- ADC结果转换到温度：
- 通过ADC结果计算NTC电阻值，单位欧姆
- 通过NTC电阻值，计算温度，单位摄氏度
> 开发板配置的NTC电阻参数如下
>
> B值 3950
>
> 常温 T2 = 25℃
>
> 常温电阻R2 = 10KΩ
- 注意：默认无法使用sprintf打印浮点数，需要在工程Properties - C/C++ Build - Settings - MCU Settings中，勾选Use float with printf from newlib -nano
