Adc Group Streaming Buffer Mode:將緩存區為線性緩衝區(buffer 滿時停止轉換)或循環緩衝區(buffer 滿時進行覆蓋) Adc Group Streaming Number Samples: 在流訪問模式下,每個通道需要獲取的 ADC 值的數量,單訪問模式下默認為 1 Adc Group In Back to Back Mode:使能
Some ADCs have a dedicated shut-down pin to shift the device into power-down mode. The weakness of this approach is that an extra pin, which results in increased pin count for the ADC, can increase the package size. Other ADCs, like the AD7887, require a write to an on-board control...

最后特别注意一点,如果STM32H7工作在400MHz,ADC使用AHB做时钟源,超频是不可避免的。ADC1和ADC2位于200MHz的AHB1总线时钟,而ADC3位于200MHz的AHB4下。根据上面的框图,ADCx_CCR寄存器的CKMODE最高可以选择4分频,那么就是50MHz,而ADC数据手册限制最高是36MHz,也就是说已经超频了。

Solved: Hi. We have an example for ADC Singal channel and multiple channels of the same group in Aurix. Now I'm trying to read the ADC data from
