Resolved! Does the DMA Arbiter allow round robin preemption after each piece of data to keep multiple peripherals going at once or does the DMA controller completely block until an entire block of data has finished transmitting?

I am working with the STM32L4S9AII6 MCU on a project where I am being asked to replace an FPGA implementation with this CPU. We are maxing out all 14 DMA streams via SPIs, I2Cs, & UART. As you can imagine, I am working with some serious hard real-tim...

RTOS multiple uart

Hello,there is some solution for sending data over multiple uarts with RTOS,because HAL_UART_Transmit,HAL_UART_Transmit_IT,HAL_UART_Transmit_DMA not send data in second uart. Still BUSY.Thank you in advantages

I have some questions about PDM2PCM library settings.

I tried to use the PDM2PCM library in the STM32L432.I have some questions about PDM2PCM library.1.The values set by an output buffer in the function PDM_Filter().We must use values in the output buffer (= PCM data stream) as uint or int ?2.I am not a...
