I’m designing a custom board based on STM32N6 and using the same boot flash as the NUCLEO‑N657X0‑Q (MB1940). In the reference design, all OCTOSPI signals to the flash have 0‑Ω bridges in series, and the traces are length‑matched including those footp...
Hi, im planing on running computer vision DL models on multiple STM32 boards. At this moment I will compare a STM32MP256F-EV1 with a STM32H747-DISCO, however i only bought the B-CAMS-OMV and is not the same connector on the MP board. IS there any way...
Hi, We have bought the NUCLEO-H533RE board and I tried to power it via E5V by connecting the Arduino Minima R4 board 5V power output into E5V and GND signals in pins 6 an 8 respectively. I instantly noticed that the LED LD3 is lit with green, but the...
I am having difficulty creating AD schematic and PCB libraries for the NUCLEO-H563ZI from the MB1404 Altium project files. The process fails when attempting to create similar components, such as resistors.Is there any chance of obtaining the librarie...
Hi everyone ! I am having problem with the I²C connection. The problem is that, normally the the SDA and SCL pins work properly (I checked it with a logic analyzer) but when I connect them to the module or sensor I use, both of them goes LOW and stay...
Hello ST Community team, On the UM1472 Rev 8, the table 9 board revision history, it is mentioned that the MB997 initial rev is the B01 and the last rev is the F01. But on the https://www.st.com/en/evaluation-tools/stm32f4discovery.html#cad-resources...
I'm trying to work with a STM32F4-Discovery board, and previously it connected perfectly okay, but a couple weeks ago something, seemingly out of nowhere, broke and CubeIDE stopped detecting the board and writing programs to it showing this message:I...
I’m testing low-power modes on my STM32 B-L072Z-LRWAN1 board and measuring the current consumption.When I measure the current using a Xiao PowerBread, I get around 20 mA on the 5 V rail, even when the MCU enters Sleep Mode.My question is whether the ...
Hi everyone,create the cubeide project for onboard PDM MEMS microphone on stm32 discovery kit. 1- I2S22-Mode: Half Duplex Slave3-DMA Settings -> add -> SPI2_TX Problem in section 3 . I cannot see the SPI2_RX which I will get the PDM peripheral to mem...
Hello I tried a blinky code which works with an other disco board I bought several months ago and it doesn't work with the new one. I tried it in debug mode and I'm stuck here.void Error_Handler(void) { /* USER CODE BEGIN Error_Handler_Debug */ /...
