I need to sample two analog channels using ADC with DMA in circular mode, but i'm not able to find any example to do that. I've found an example where it's used the ADC with the DMA but after each EOF DMA interrupt the ADC and the DMA are restarted. I don't want to do that...

I'm working with stm32f411re uC and a TI audiocodec through I2S2 interface in full duplex master. I generate the project using CubeMx 5.5 and HAL driver 1.24.2. I configure the I2S module to use DMA on both, tx and rx in circular mode. I...

如果没开中断就用查询的方式,下面是DMA1 Channel5的,其他通道类似 /* 等待DMA传输完成 */ while (!DMA_GetFlagStatus(DMA1_FLAG_TC5));/* 清除DMA完成标志 */ DMA_ClearFlag(DMA1_FLAG_TC5);/* 关闭DMA传输 */ DMA_Cmd(DMA1_Channel5, DISABLE);执行完上面后就可以接着下一次发送了,...
