Resolved! I have create a project to communicate via a fdcan bus on stm 32h723zgt microcontroller but i have no interrupt generated
i have connected the tx pin to rx pin on fbcan3 interfaceyou will find my project in attacheementthanks

Weird PWM Timer3 master and PWM Timer1 slave behaviour
Hello, I have a timer 3 master and timer 1 slave. When a button is pressed, master is activated as long as button is pressed, and then slave is triggered based on master's output signal (high / low) (gated slave control)(This is a continuation of my...
STM32F746GDISCOVERY, PWR_PVD, STM32CubeIDE
I want to make an interrupt when power > 2.0V. STM32CubeIDE generated:/** * @brief NVIC Configuration. * @retval None */ static void MX_NVIC_Init(void) { /* PVD_IRQn interrupt configuration */ HAL_NVIC_SetPriority(PVD_IRQn, 8, 0); HAL_NVI...
Hello I'm useing UART with a CTS line for hardware flow control. Is there any way to configure an interrupt for the same pin where the CTS line is connected? Can i call any callback function that i didn't find?
I'm working on a STM32MP1xx board and I'm useing only the Cortex-M4 for this UART configuration.
Resolved! RTC inaccuracy induced by internal clock source?
I'm using the STM32L431xx mcu. The current hardware configuration of our design has no external clock source (crystal), so we are using the internal one. And there's a new functionality which demands second-accurate real time clock, over a period of...
I2C in DMA mode - deadlock on I2C interrupt
Has anyone have similiar issues ? I got I2C DMA writes working nicely on table, but in real application there are disturbances which cause false start condition on the bus.This happen when I2C HAL driver has "lock" on I2C handle - so incoming interr...
program counter is hitting WWDG_IRQHandler without enabling the Watchdog. what could be the problem/ cause for this
Hi,please find the attached register values of WWDG register on Reset positionRegards,Sudheer
Forcing Capture-Compare-Register to clear [STM32H7]
I'm trying to count the number transition during the time another process is taking place. Don't need frequency, just the counts.So I've enabled TIM8CH3 for capture-compare, and have verified that CCR3 does change when there are transitions on th...
Interrupt mapping to NVIC ISR vector
I was looking at the ARM M7 reference manual, and it shows an empty NVIC ISR vector from 0x40 to 0x3fc. When I look at the file startup_stm32h725xx.s it defines specific interrupts mapped to the ISR vector. Are these hard mapped by the EXTI block an...
Resolved! STM32H7 Hard Fault when RCC at 165 MHz
I have the STM32H7B3I-DK (MCU: STM32H7B3LIH6Q), and I am trying to get the sys_ck close to its maximum frequency of 280 MHz, by running HSI or HSE through PLL. The trouble is that I can only get up to 164 MHz. Any higher and I get a hard fault. Is th...
