在嵌入式开发中，ADC多通道采样与DMA传输是数据采集系统的核心。STM32H743凭借Cortex-M7内核和高速Cache，大幅提升性能，但也引入了Cache与DMA内存一致性问题，导致数据错乱、传输中断等异常。理解Cache工作原理与MPU配置，是确保DMA可靠搬运ADC数据的关键。合理运用Non-Cacheable区域、DMA循环模式及中断 ...
如果阻抗更高，设 387.5 或 810.5 周期。 实操心得：采样时间不是越长越好。 采样时间太长会降低有效采样率，而且如果触发频率很高，ADC 可能还没转换完下一次触发就来了，导致触发丢失。 我的经验是先用 64.5 周期跑，看数据稳不稳，不稳再往上加。
美信就不说了，我不是特别了解它的历史，但产品非常的个性。 我闲鱼买了两颗很古早的芯片 第一次见这种的封装桶 我的显微镜不太好，直接拍一张 （评论区有个大佬当年还参与过这个芯片的 ...
