We are developing a software application that uses GPIO interrupts.We want to set interrupts on the same pins (PE8, PG8), but only one of them can be set to external interrupt mode in the ioc.Is it not possible to set external interrupt mode for two ...
This question is about the operation of HAL_SPI_TransmitReceive_DMA.When HAL_SPI_TransmitReceive_DMA(&hspi1 ...) is being transmitted (assumed SPI communication_A) and HAL_SPI_TransmitReceive_DMA(&hspi1 ...) is called (assumed SPI communication_B) SP...
How to cancel HAL_SPI_TransmitReceive_DMAWe are developing SPI communication devices using HAL_SPI_TransmitReceive_DMA.We would like to cancel or stop HAL_SPI_TransmitReceive_DMA even in the middle of transmission by GPIO interrupt, but we do not kno...
We are developing using STM32H743.We want to set 100MHz for SPI1 CLK and 117kHz for SPI2,3. However, we cannot set it because of "clock tree" and "maximum divisible limit is 256".Is there any way to achieve the above configuration?
SPI CLK frequency dividing methodIn microcontroller (STM32H43), SPI1, 2, and 3 use a common CLK Source.Is it possible to separate these CLK Sources?Also, I would like to divide SPI2 and 3 more than 256 divisions, but is that possible?Please help me.
Thank you for your answer. I see. I understand.I have one more question. Is it possible to disable only the USB interrupt? Also, how should I write this in the program?
