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...
Hi all,I want to access a NandFlash(H27U1G8F2B) chip which is extended by STM32F429BI's FMC;According the datasheet, seems the default value after erase is '1' for each bit.But I read the value by program is '0':My test code as below:#define TEST_NUM...
Hi,I going to choose "B-L4S5I-IOT01A" this board for my project (it is combination of ADC and IOT), can please in which IDE version having all these libraries for ADC and Wi-Fi on this board.Thanks,
We're running into what seems to be a low-level race-condition when initializing LWIP on boot. The LWIP always initializes successfully after using the STLink to flash the .elf either in debug and release modes. After flashing, I verify by sending a ...
Hi,I'm a little lost, I would like to use the alternative6 (AF6) function on my stm32f405. I tried to do it via cube mx by configuring the pins but the generated code seems strange to me :So for me I'd like to use SPI3 with PB3/4/5 so AF6 in datashe...
Hi, I integrated the OpenBootlader for the STM32L552 to my project and it works normally as expected. I'm only using the UART interface and reduced the boot loader project to the minimum.The problem I'm facing is that sometimes the flashing stops, be...
I am working on a ThreadX project on my STM32H747I-Disco with M7 and M4 cores. I want to allocate memory dynamically in the initialization phase that can be accessed from both cores. For this, I am planning to use the "tx_byte_pool_create" and "tx_by...
We notice, after a certain time, a totaly break of UDP/IP communication (LwIP layer) of our STM32H7 project (FreeRTOS layer is also used).This stop occurs without any particular external condition and generally after a fairly long time (after a few h...
Dear STM32 communityI am trying to setup the ST7735 Display (ST7735) with SPI and DMA for a faster refresh rate. Without DMA everything works fine. When i setting up DMA nothing is displayed on the Display.My DMA and SPI Settings are:I want to fill t...
Hello! I'm a firmware design engineer, and along with my team, we're working on UWB development. We recently received a Qorvo kit (DW3300QDK1) along with the EVB STM32 Nucleo-F429ZI to work with their SDK. However, we couldn't find any documentation ...
Hello im working on a project where im modifying data on STM32 and transmiting it via UART on my other hardware(ESP32).Im having troubles, my best guess is at sending data thought UART. Because of the delays in my code I've implemented DMA which woul...
