event和interrupt的区别在于,interrupt在于软件,触发后,会使用中断回调函数作为处理。event在于硬件,会导致一些外设做出一些动作,但是不需要使用中断回调函数。 比如说,用定时器中断,然后在回调函数里写读取ADC数据。用定时器事件,ADC事件触发转换,这就不需要内核操作什么软件了,然后DMA传输放在RAM里,这一整套采样,数据传输...

The main reason is that without DMA, zephyr is not fast enough to handle every EOC interrupt signals, which will end up with overrun errors. By the way, the DMA driver is very close to the end in #19712 . Collaborator cybertale commented Oct 17, 2019 Add support for multi-channels co...

44.2.2 ADC时钟源选择 ADC有两种时钟源可供选择,可以使用来自AHB总线的系统时钟(属于同步时钟,对应下面框图的adc_hclk),也可以使用PLL2,PLL3,HSE,HSI或者CSI时钟(属于异步时钟,对应下面框图的adc_ker_ck)。 结合上面的框图,ADC的时钟源要注意以下几个问题: ...
