Ask questions and find answers on STM32 hardware set-ups, including schematic-related challenges, debugging probes, power configurations, and more.
On the phase outputs why are there ground cutouts on the layout for this reference design. Is there a risk to cross couple to the ground plane with the switching noise or is it for thermal concerns?I've seen this in several ST ESC designs for drones ...
Dear all!this is the first time i design PCB for STM32H755, as my understand for direct SMPS that i design like attach file, really i don't know is it correct, so can you help take look and let me know if any mistake.
Been working on the Nucleo H5 dev board for about a month. Everything with the built-in ST-Link/V3 was fine until randomly yesterday, the board would no longer get out of reset when the ST-Link is powered. Board powers up and boots if getting powe...
Is there ST-Link V2 driver for Windows 11? I am using Microsoft Surface Pro + Copilot and trying to load code on STM32L476.
Hello community, I have thiss board, the first one I'm designing from scratch on stm32 platform. I am able to connect and program just fine to some of the MCUs, but for the vast majority, the chip somehow gets fried before I can program it: I can'...
It's possible to set an interrupt priority for a pin in STM32F411 MCU, right? My PC13 pin (user button) is set to GPIO_EXTI13 and I want to give it the preemption priority 3 in the NVIC (STM32Cube IDE ver: 1.18.1) but it's seemingly not possible! Its...
Hello everyone,I am working right now in a project involving some of ST products. I have my custom HW board with a STM32G0B1 MCU for a specific functionality. In order to work with it and be able to program and debug my project, I was using two main ...
Hello, I am using STM32H743BIT6 as a MAC for DP83TC814R Ethernet PHY, I have one query regarding oscillator, I am using Ethernet in RMII slave mode which requires 50MHz reference clock, can i use the same clock which i am using for MCU HSE or should ...
Hello,I have ordered a X-NUCLEO-PLC01A1 for my Nucleo Board F767Zi.I should receive it soon but I would like to understand it as much as possible.This is why I try to find some example projects but I cannot find any.In addition, I have tried to downl...
This question pertains to the (relatively) new STLINK-V3MODS programming/debugging device.The UM2502 Users Manual for this product goes into great detail about using Pin #22 of the castellated edge connector aka +5V for ancillary purposes:"Pin 22 of ...
