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...

AN2834 Rev 10 9/53 52 ADC errors AN2834 Example For the STM32 ADC, the smallest detectable incremental change in voltage is expressed in terms of LSBs: 1 LSB = VREF+/4096 (on some packages, VREF+ = VDDA). If VREF+ = 3.3 V, the input of 402.8 µV (0.5 LSB = 0.5 ×...
STM32对HAL库的ADC(多通道DMA) 2019-12-13 19:47 − 多通道的adc就是检测多个通道的电压值,用dma来检测。 cubemx中设置如下。 Number of conversion 的个数就是该adc中要使用的通道数。在下面的rank中设置通道的采样时间和通道... 无乐不作丶 0 18487 STM...

32. 33. 在adc.c中void MX_ADC1_Init(void)是ADC的初始化,与STM32CubeMX中配置的一样,也可以在此处修改 第一种ADC多通道采样方法: 1.在main.c定义一个数组作为转换数据缓存数组 /* USER CODE BEGIN 1 */ uint32_t ADC_Value[100]; uint8_t i ; ...
1. 配置STM32CubeMX 2. 复制stm32xxxx_hal_msp.c文件 将CubeMx 生成的代码 stm32f7xx_hal_msp.c 函数复制到 RT-Thread Studio 生成的工程中,并参与工程编译: 由于我们并没有使用 CubeMx 生成的工程,所以这里需要将 stm32f7xx_hal_msp.c 文件中 #include “main.h” 替换为 #include “board.h”。
AN4195 Application note STM32F30x ADC modes and application Note: Introduction This application note presents an overview of the ADC peripherals in the STM32F30x microcontroller families, and explains how to use the various modes and specific features of the ADC. Its purpose is to help ADC ...
在STM32F429I-DISCO board中,由于串口2被L3GD20和液晶数据线占用,所以串口1很方便,而且还留了2个孔外接。 This example describes how to use the ADC3 and DMA to transfer continuously converted data from ADC3 to memory. The ADC3 is configured to convert continuously channel13. Each time an end o...
