I wonder if a regularly or sporadically missed clock pulse on the HSE clock input has any (negative) effect on the operation of the H7 processor or any clock output from a HRTIMER.My guess is that the internal PLL might lengthen the next pulse a litt...
Or at least make software reset work on only one core?Thanks
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...
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 ...
Announced over a year ago - I developed a product based on it and still no silicon
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...
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...
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...
