Will the data of FIFO be flushed when multiple streams start simultaneously in the same DMA.

For example,One stream use FIFO and the other stream does not.What does FIFO behave like when two streams are started at the same time?

How to generate Center Aligned PWM with variable duty cycle that has PWM frequency of 1.5MHz with dead time insertion?

Hello,I need to be able to generate a center aligned PWM signal on two Ch. with 1.5MHz PWM frequency. The duty cycle variation will have dead time inserted in it. In order to generate 1.5MHz for center aligned signals, I need to calculate ARR Registe...

Hello, I am using STM32L4xx MCU, the UID is 96bits, I have got the 96-bit. Unfortunately I have only 64 bits space for serial number. so I have to convert the 96-bit to 64-bit, and the converted 64-bit must be unique. does anyone have the solution?

STPM4Raspi

Hello,I'm using STPM4Raspi (ST33TPHF2ESPI) on Linux.For performance reasons, I would like to use the Linux driver (tpm_tis_core.c) in interrupt mode. Hence I've added the support in the Linux device Tree. The linux driver tries to probe the interrupt...

U suffix in part number?

Datasheet does not say what U suffix means in part number.I.e., what is the difference between STM32H7xxVIT6 and STM32H7xxVIT6U?

STM32F373 firmware to continually update SDADC gain in a loop

Hi, I'm using STM32F373 for a biosignal measurement project, and I need some help writing firmware to automatically update the SDADC channel gain during execution.For example, I'm sampling at 100Hz, and after every 100 samples, i want to change the g...

STM32F767 QUADSPI with DMA

I've referred STM32F769I_EVAL QSPI with DMA source code and implemented same way for STM32F767 but its not working. can anyone provide the sample code for STM32f767 QSPI with DMA
