When performing ADC acquisition on STM32, the difference in time efficiency between using software (interrupt or polling) to transfer data and using DMA to transfer data is very significant. This difference is mainly reflected in CPU time consumption and system responsiveness, rather than the time taken for a single sampling conversion itself. For example, consider … Read more
HTTP/3 is the third official version of the Hypertext Transfer Protocol (HTTP), which aims to improve network performance and stability while addressing various security and privacy issues. However, it still faces some security challenges. HTTP/3 no longer uses the Transmission Control Protocol (TCP); instead, it employs the QUIC transport protocol proposed by Google in 2012. … Read more
