WebNov 2, 2024 · 转换时间. 采样周期最小是 1.5 个,即如果我们要达到最快的采样,那么应该设置采样周期为 1.5 个周期,这里说的周期就是1/ADC_CLK. ADC 的总转换时间跟 ADC 的输入时钟和采样时间有关,其公式如下:. Tconv = 采样时间 + 12.5 个周期. 其中 Tconv 为 ADC 总转换时间,当 ... ebay 6 volt honda rectifier upgrade ct200 https://shoptauri.com

STM32F4: How to get data from multiple channels sampled from a single ADC?

WebThe HAL library had the same bug as the code above. To solve it, either: Set the CR2_DDS bit, as in the accepted answer. However this might cause overrun error, as data is continuously converted. Clear the CR2_DMA bit before setting it again (or call ADC_HAL_Start_DMA) to start the sampling again. WebDemo 3: DMA with ADC. The DMA is a great tool to use with the ADC when you want to transfer lots of samples to memory continuously. It can be used for audio sampling, a custom oscilloscope, etc. The STM32 HAL makes it a little easier to use, as there’s some built-in functions that control the DMA with the ADC, specifically. WebApr 27, 2024 · 5. After you start ADC with HAL_ADC_Start (), hardware starts ADC conversion. This conversion takes some time. Exact time depends on your ADC configuration in Cube, the greater value of ADC prescaler and cycle count the longer it takes.
