ADC internal design is a switched-capacitor type. The following figures (Figure 1 to Figure 6) explain the principle of ADC operation. The example given below shows only the first steps of approximation but the process continues till the LSB is reached....
SAR结构的主要局限是采样速率较低,并且其中的各个单元(如DAC和比较器),需要达到与整体系统相当的精度。 The ADC in STM32x microcontrollers uses the SAR (successive approximation register) principle, by which the conversion is performed in several steps. The number of conversion steps is equal to the n...
The ADC in STM32x microcontrollers uses the SAR (successive approximation register) principle, by which the conversion is performed in several steps. The number of conversion steps is equal to the number of bits in the ADC converter. Each step is driven by the ADC clock. ...

STM32CubeMX配置 选择芯片stm32f103c6t6,新建工程 设置时钟源,最小系统外部晶振8Mhz,作为外部高速HSE时钟源。由于没有外接外部低速晶振,这里低速时钟源选择旁路时钟源。 配置时钟树,这里使用官方推荐的配置 为了展示内部温度的变化,我们配置USART1,打印获取温度的结果 ...
一般主时钟都是用72M，所以14M的ADCCLK不大好生成，所以是我用的是18M了。不过STM32的质量很不错，...
