STM32 MCUs Embedded software

If I allocate USB peripherals to M7 core along with SPI, memory interfaces, will M.7 core ses performance bottleneck?

STM32H750; Ethernet; open new Socket; to connect to another embedded device.

I need to establish an Ethernet connection between two embedded devices. From a PC I can connect to my application or to the other device and exchange messages. How do I do this on my H750. How do I open a connection from my device if the IP and port...

STM32L4 USB-enabled dev board not appearing on computer

Hello, I have a STM32 Nucleo-64 development board with the STM32L476RG MCU on it.. I have made a small PCB that, among other things, brings the USB interface to a connector. I have implemented a simple USB configuration following some online tutorial...

Ethernet TX doesn't work because ETH_DMATxDescListInit() doesn't initialize the entire ETH_DMADescTypeDef

The officially recommended recipe for lwIP on STM32H7 puts the ethernet DMA descriptors in SRAM1. SRAM1 is not zero'd by the default startup code.It's unsafe for the network drivers to assume that buffers and critical data structures live in .bss.F...

SPI is always stuck in busy state

I have found several other forum posts on this subject, and I've tried to follow them, but I'm still stuck. For some reason, SPI3 on my bl47eio1a never enters a ready state. It gets stuck waiting for a ready state before it ever can send or receive a...

STM32H7 SPI low level driver

I am trying to run the SPI peripheral on STM32H757 using low level drivers but no luck at all. The STM32cube H7 package contains example for controllers which has no FiFO, . Thus the examples cant be directly use. Also i have cherry picked quite alot...
