WebThe SPI supports master and slave mode : (#) There are two modes of transfer: (++) Blocking mode: The communication is performed in polling mode. The HAL status of all data processing is returned by the same function. after finishing transfer. (++) No-Blocking mode: The communication is performed using Interrupts. WebWhat exactly is throttling the SPI transfers? If you're using DMA directly (rather than triggered by a timer or something else), then as soon as the SPI is free, the DMA peripheral would start another transfer. As a result, being busy all the time would be expected. how many km is mount everest https://sportssai.com
