Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
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...
HiI found something strange in cmsis dsp source.I am using stm32f429 and LITTLE ENDIAN and cmsis dsp library V.1.5.1.in cmsis dsp library(arm_mult_q31.c) :void arm_mult_q31( q31_t * pSrcA, q31_t * pSrcB, q31_t * pDst, uint32_t blockSize){... whil...
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...
Hello, I'm able to connect the STM32CubeMonitor-UCPD with NUCLEO-G071RB and X-NUCLEO-SNK1M after following the instructions in AN5418. I only changed port 0 Sink PDO1 to 0x020641F4.I want to use the setup as a sink and always want to get the maximum ...
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...
I'm trying to send udp data from stm to server. But when i observe in Wireshark, the protocol shown as ECHO, not UDP. What is the reason?
Hey together,I have a question regarding the STM32H7 ethernet interrupts. I have lwIP + freeRTOS running successfully on the device. All fixes which were indicated by @alister were applied and it runs quite stable. The strange part is that when I ap...
Hi,I am currently writing an application for a STM23F769i-DISCO that uses the USB peripheral as a device starting from a project generated with touchGFXDesigner.All seems to work when I am not enabling the DMA for the USB, but when I enable the DMA I...
I made this sauce to implement lwip tcp serverIf you try to remove the st-link wire and do it without debugging, the server itself doesn't workI try to find a way, but I don't know where the problem isIf the LED on the board blinks, it means it's dow...
I wrote a Bootloader for my STM32F042k6 board that functions pretty well. On System Reset the Bootloader is launched and can later jump to the Application. That was great:). Now I wish to do the opposite in my Flash. I wish Launch my Bootloader at a ...
