Get early access to the next-generation STM32Cube HAL drivers for STM32U5A major update to STM32Cube HAL drivers, called HAL2, is now available for preview on GitHub. It supports the STM32U5 series. Building on over 10 years of experience, HAL2 deliv...
Hi all!On an STM32 project I'm working on, I want my USB port (USB C in that case) to work either in Host Mode or in Device Mode, depending on a menu change from the user. For added context, this is for a MIDI project in which the MC will either use ...
I am using two STM32H503 boards. One is programmed as an I3C controller, the other as an I3C target. My goal is to have the target send an IBI on the bus and the controller will receive the IBI and then immediately issue a pended read -- there will...
I am connecting a TCP/IP stack to the HAL_ETH driver of an STM32F7xx. I am using https://github.com/STMicroelectronics/STM32CubeF7/blob/master/Projects/STM32F767ZI-Nucleo/Applications/LwIP/LwIP_HTTP_Server_Netconn_RTOS/Src/ethernetif.c as a starting ...
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...
Hello,I am developing a RAM-based bootloader on STM32H5, to update my firmware application.Application and bootloader resides on different flash areas, and the bootloader code is copied into RAM at startup.[0x8000000 - 0x801FFFF] bootloader[0x8020000...
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 ...
