Is it possible to reset the CM4 from the CM7 on the STM32H747?
Or at least make software reset work on only one core?Thanks
Connecting PWM output to input on the same board
Good day everyone,At the moment I'm trying to connect a PWM output pin to a PWM input pin on the same board. I'm using a dual core MCU, so both of them are on a different core.I set TIM4 to the M7 and TIM15 to the M4. I enabled the interrupt for TIM1...
[STM32H7] Why is there no spread spectrum functionality?
Hi,as there is apparently no more spread spectrum functionality in the STM32H7 to reduce EMI, is there some counterpart? I heard that the PLL fractional divider might be used for that purpose, but the amount of processor overhead to change the three ...
Is the STM32H7A3RIT6 ever going to exist?
Announced over a year ago - I developed a product based on it and still no silicon
Resolved! STM32H743-EVAL2, why battery-backed RAM doesn't hold data?
I start from any simple Cube example, such as UART_Printf,enable access to the backup RAM and write some data.After reset by the reset button or NVIC_System_Reset data in the backup RAM is retained.But after powering off the data is lost.Do I miss so...
Resolved! Could anyone help me calculate TIM frequency?
Hello everyone,I'm using TIM3 on my Nucleo H745. If it's correct this TIM gets fed from the CPU clock, so it runs at 480MHz. That's what I thought at least.Using these settings;htim3.Init.Prescaler = 48000;htim3.Init.Period = 10000;To my calculations...
How to implement the TIM_IRQHandler when using other classes
I'm trying to make a scheduler and everything seems to be ready, now the final step is add the proper function to the IRQ_Handler. This is where my problem starts. At default this uses a extern tim object from the main.c. I removed it there and put i...
