External SDRAM performance vs data width (8, 16, or 32)

I'm adding external SDRAM to a project and I'm trying to decide which data bus width to choose, 8, 16, or 32 bits. Do the wider bus width options significantly affect external SDRAM performance? I have been poring over the AN4891 app note but it ...

CPU cycles spent (MOOC - MOOC - STM32F7 hands-on workshop)

Hello, I am following " MOOC - MOOC - STM32F7 hands-on workshop" from STM official YouTube channel . In workshop there is example code to measure number of clock cycle spent for piece of code with TIM_MEASURE_START and TIM_MEASURE_END. As there are...

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...
