Hi everyone,I'm building a watchdog application on the STM32 NUCLEO-U385RG-Q using the Arduino IDE and the IWatchdog library. Since the library doesn’t support early interrupt callbacks, I modified it by adding some LL code (afterLL_IWDG_SetReloadCou...
Hi guys,I'm coming from Arduino and recently started working on a project where I need a protocol that supports bidirectional communication between MCUs and Hot-Join.I decided to give I3C with the STM32H5 a shot and got myself some Nucleo-H503RB boar...
Could you please explain why global interrupts are disabled (using __disable_irq()) at the beginning of the LPTIM_Disable() function, and re-enabled at the end?Does this relate to ensuring atomicity during the timer's register save/restore process, p...
On STM32F4, when you choose PLLCLK as the MCO1 source, does the HAL actually routes the PLL output going into SYSCLK, i.e. after the PLLP division?#include <Arduino.h> #include <RCC.h> void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscIn...
Hello there,I cant find full working example about ram initializations and relevant RISAF settings,I need to get at least 2.5MB region for camera data capture, I found clk and power enable functions, but it does not working, when I increase memory si...
Hello everyone, I'm currently working on Ethernet communication between my STM32H563ZI and a TP-Link router. They are connected by Ethernet, and I'm trying to ping the router with my STM32. All is going on, except the DHCP who don't want to connect ...
I have USB2 OTG high speed port1 working in "device mode" on the STM32N6570-DK board. I need to transfer an image file (around 10 MBytes in size) from the external PSRAM IC (APS256XXN-OBR-BG Hexadeca‑SPI PSRAM) to external PC via a bulk CDC IN endpo...
Hello STM32 Community,I am working on the STM32F769I-DISCO board and would like to implement UDP communication using LwIP with FreeRTOS.I have already downloaded the STM32F7 series example projects, and I see that the LwIP_HTTP_Server_Socket_RTOS exa...
Hi. I have a problem while using lwip and freertos. The board is based on stm32h743vih. The mpu configuration is done correctly i think. My problem is after i start udp server and start to send data with udp, everything is ok, but after a while i wil...
Hi, I'm not able to find any DMA available with CAN peripheral in STM32G4. After going deep search I found there's no such native DMA request available for CAN peripherals. So, I want to know is it true that STM32 controllers don't come with DMA with...
