Hello ST community! I have a question about FMC on STM32H745ZITx (LQFP144). In the datasheet DS12923 (https://www.st.com/resource/en/datasheet/stm32h745zg.pdf) it is not said whether it supports SDRAM. And there is no "SDRAM" item in the FMC settings...
Greetings all,Is there a way to configure TIM12 to be clocked by TI1FP1 and reset (with trigger to continue counting) via TI2FP2? Or is this going to require some hideous multi-timer contraption?Thanks,Dave
Hi,I am using a custom board equipped with an stm32f417VGT and an external SLC NAND flash (more specifically S34ML02G).Through reading and writing from GPIOs I successfully "bit-banged" the read and write operations between the MCU and the NAND flash...
Hello,I am learning MDMA, and have been able to make it work in different scenarios, but I am now stuck.I want to use MDMA to chain DMA transactions without CPU intervention.What I want to do with mdma linked list is :° configure timer in output° use...
My application is to implement a real-time signal processing algorithm on the STM32F3 microcontroller. I'm not using FreeRTOS.Details on what I want to do:I'm planning to use ADC in dual interleaved mode, which would result in a sampling rate of arou...
I'm using a STM32L072CZT6 in a mobile application in which I need the MCU to start up as fast as it can. Currently the start-up time is 6ms. That appears to be too long based on this thread (Start-up time too long), although I haven't found a typical...

Hi, I have a custom board based on the STM32H745 and I'm trying to understand an issue I'm experiencing with the SPI Interface. I have a BMP280 attached to SPI1 on the M4 coreand I've successfully written a driver for it both using DMAs and Interrup...
In STM32F407 locked to RDP Level 1, with a battery on VBAT, I keep some (not critical) data in the RTC Backup Registers. In an attempt to investigate an incident, I tried to read out content of these registers using SWD. While I was able to read RTC ...
