Dear All,Board: Nucleo - H745ZI-QWhat am I trying to do ?I am trying to measure pulse width of an signal using input capture mode of timer 2 channel 1. Then multiply that width by two and wait for that much time and generate an output pulse using out...
I configured timer1 for pwm generation center aligned like below in cube ide.I update duty cycle writing directly CCRx register asyncronously in the code.Most of the time pulses are effectively center aligned but sometimes not (nor left or right ali...
Dear All,Board: Nucleo - H745ZI-QWhat am I trying to do ?I want to measure pulse width of an input signal using a busy loop and a timer. I keep monitoring a pin configured as input , when a zero is detected (by default input is around 3 volts), a fun...
Documentation say ADC have max 4Msps, but it refer olways to 60MHz to adc (60MHz * 15 cycle = 4Msps) but manual say ADC max frequency is 170MHz, then 170MHz * 15cycle = 11Msps.This clock is different from Fadc (aka adc kernel clock)?https://www.st.co...
Hi,i'm working on a STM32H755II MCU, I followed this guide and setup two debug configurations one for CM7 (that downloads both codes) and one for CM4. I added on the CM7 project the common implementation for printf:int printf_swo(char *ptr) { uint32...
I ran timer OC mode on PA8 (TIM1_CH1) on STM32f407VGT6 using HAL and it works fine. Then I decided to set up it by means of LL and there is not any output on PA8. I checked my code with Example_LL projects of STM32F411RE-Nucleo in ST F4 repository. I...
There are several FDCAN peripheral registers on the STM32H743 that hold the starting address of various elements used for FIFOs and filters. Are these addresses relative to 0 or to the physical address of the FDCAN message RAM (0x4000AC00)? The Refer...
I tried to set a STM32F469 controller into standby mode and wake it up periodically via the RTC on a custom board and on a STM32F469I-Discovery board. I had the problem that the controller only went into standby once, on the following runs it woke up...
Hey there, I'm using a stm32f103c8. I want to define an internal interrupt so for example when a counter reaches a certain value, the event happens and the interrupt performes. how should I do that?
i have an application using screen and required external flash i used this flash MT25QL256ABA8E with STM32F769IITx on designed board but when flashing code on kiel i can't find the suitable external flash flashing algorithm .is there available one ...
