Connectivity to external NOR Flash Memory using DMA of STM32F446RE

Hi,Am trying to correctly connect to my external NOR flash memory using my STM32F446RE's DMA.Am not sure how to go about this and the libraries I have tried are not working at all.Here's a link to the library I tried to test the connectivity between ...

Resources for SPI connection to external flash memory

Hi,I would like to know if there are any resources for learning and understanding how to communicate (read/write/erase) from an external flash memory using SPI.I am using an STM32F446RE and my external flash memory is a w25q128.Ideally I would like t...

Does the FMC support bit swapping/byte lane swapping on the STM32H745?

Hi,Just looking for confirmation that the FMC SDRAM controller supports bit swapping within byte lanes, and byte lane swapping (including the mask bit of course) on the STM32H745.We are implementing a 32-bit SDRAM interface, and I don't see any menti...

I am using NUCLEO-G0B1RE, I wanted to implement a project using NFC06A1 with the mentioned board. I found no example for this anywhere. Can someone provide me an example using SPI ? (Didn't find example in STM32CubeIDE)

STM32H7 - Sending CMD5 to eMMC card

Hi,I'm working with an STM32H7 connected though SDMM1 (1bit bus width) with an eMMC, I need to put the eMMC into sleep mode so we can reduce the power consumption when it is not being used.According to the information I've been able to find we need t...

Signal Integrity Simulation with IBIS model of STM32H7B3IIK6

Hello.I have got the IBIS model of STM32H7B3IIK6 from ST website, but there is no document to explain how to use this IBIS model. As there is so many sub-models included, I don't know what model I should selected for the FMC data pin, e.g. io8_ft_fs_...

Raw RNG samples STM32F7: has anyone already tried it?

Hi,I am actually trying to collect raw samples from TRGN module of a STM32F7.To be more clear, raw sample means unprocessed data coming directly from the source. It is possible using a special IO configuration setup and external equipment in order to...

I2C flag RXNE automatically clear before read register

I initiate reception from the microcircuit for stm32h723. However, the code hangs while waiting for the RXNE flag. In the debug, step by step, you can see that the flag is set after START, but is immediately reset to zero in the next step, before che...
