ADC_Mode = ADC_Mode_Independent;在这个模式下，双ADC不能同步，每个ADC接口独立工作。所以如果不需要ADC同步或者只是用了一个ADC的时候，就应该设成独立模式了。 Mar 24, 2019 · In ADC DMA mode, when the ADC is finished with each sample, DMA transfers that sample to memory. –Scan mode, which converts a complete set of pre-defined programmed input channels, in single-shot or continuous mode. In this tutorial series, you’ll learn everything about ADC in STM32 microcontrollers. May 18, 2024 · 1、Scan Conversion Mode 在STM32微控制器的ADC（模数转换器）中， Scan Conversion Mode（扫描转换模式） 允许你在一次触发或启动下，对多个通道进行顺序转换。这个模式特别适用于需要采集多个模拟输入信号的应用场景。 Nov 20, 2024 · 在 STM32 ADC 中，连续模式（Continuous Mode）、单次模式（Single Conversion Mode）和扫描模式（Scan Mode）是三种常见的工作模式，它们各自适用于不同的应用场景。下面将逐一介绍这三种模式的区别及其特点： 1. 3、Scan Conversion Mode（扫描模式）4. enabled-continuous conversion mode. enabled *should the end of conversion selection be: end of sequence or end of single conversion. 1、ADC_Setting4. The interrupt-based reading is impossible to implement and the polling method can potentially cause your system to fail (halt forever) or get the channels’ readings mixed up no matter how hard you try to build a perfect state machine to capture the readings at the right time. 开始转换ch0（adc_sqr的第一通道）2. We will cover how to use the ADC in different modes, that includes polling mode, interrupt mode and the DMA mode. The multichannel, or scan, continuous mode can be used to convert some channels successively with the ADC in independent mode. Continuous Conversion : Enable for uninterrupted ADC sampling. You can start this mode with the CONT bit at 0 either by se tting the ADSTART bit in the ADC_CR register Jul 25, 2024 · -scan conversion mode. 0 1 / 12 www. enabled-discontinuous conversion mode. 1.

Scan mode, which converts a complete set of pre-defined programmed input channels, in single-shot or continuous mode. It seems the pointer to the buffer array is not correct or the DMA is not incrementing to the next index. Similar to a conductor guiding an orchestra, Scan Mode automates the process, smoothly moving from one channel to the next without manual intervention. To initiate this project, we'll start by enabling ADC Scan Conversion mode, followed by configuring the ADC conversion in regular mode. 2、Resolution（分辨率）4. 9w次，点赞71次，收藏329次。文章目录一、前言二、Cloack Configuration三、ADC1 Mode and Configuration四、Configuration4. 4. 6 Scan Conversion mode. You’ll learn how STM32 ADC Multi-Channel Scan mode works and how to use it to read a regular group of multiple ADC channels and get the conversion data using Polling and DMA with the STM32 HAL API functions. This mode is similar to the multichannel single conversion mode except that it does Oct 5, 2019 · Using the STM32F303RE Nucleo, I need to put ADC1 in scan mode so I can read multiple channels. In scan mode, the ADC sequentially converts multiple channels, each identified by a specific rank. In yor case, the DMA counter goes to zero after storing the second variable. 4、Continuous Conversion Mode（连续转换模式）4. –Discontinuous mode, converts only a single channel at 3. Then you can extract the two variables sample to your 100 or whatever count buffer using the appropriate call as illustrated in the ADC DMA example. This mode is used to scan a group of analog channels. In the LQFP128-pin packages, two VREF+ pins are available. 转换完成后停止，等待adc的下一次启动，继续从第一步开始转换在连续转换模式下：启动adc1，则1.
