STM32 serial port DMA problem detailed

Yesterday evening on the STM32 serial DMA problem tangled for a long time, so this morning to write a blog to talk about my understanding of serial DMA transmission. Discuss three issues: 1. What is a serial DMA request; 2. Brief review of the

What are the audio encoding formats

The sound in nature is very complex, and the waveform is extremely complex. Usually we use pulse code modulation encoding, that is, PCM encoding. PCM converts continuously changing analog signals into digital codes through three steps: sampling, quantization and coding. At pre
