Dma_fifothreshold_full
Web我可以回答这个问题。设计一个基于串口的c代码需要考虑串口的通信协议、波特率、数据位、停止位等参数的设置。 WebAug 19, 2024 · Most DMA controllers allow you to increment one of the two pointers by zero, so you keep transferring to or from the same address (which is typically a peripheral register). And even if the port peripherals are somehow "consecutive", the data registers almost certainly won't be.

WebUsually, the peripherals attached on the I2C line take longer than the STM32 to initialise and come out of reset. The I2C initialise should be delayed (sometimes for many ms). It should also check the bus state. All comms functions should also check the bus state before attempting to access the bus. Expand Post. WebFor the STDPERIPH version, the timer for BREAK detection works fine, and *should* trigger a DMA transfer for the expected 512+1 bytes (513 total size). Confirmed with logic analyzer, it can toggle a pin after each BREAK is detected, but …
