Here SysTick_Config(16 000 000) takes one second to count down from 16 000 000 to zero?That is, one tick has a duration of 1/16 000 000==62.5 ns ?0.0000000625(one tick time) *16 000 000 ticks== 1 secondCorrectly?At the end of each count, an interrupt...
I have set Timer 8 to PWM Generation CH2 CH2N. Based on the value read by the ADC, I want to change the polarity of both CH2 and CH2N. I have found that using __HAL_TIM_SET_CAPTUREPOLARITY, I could change the polarity of CH2 but the polarity of CH1N ...
My background is in hardware, but I have extensive experience writing "bare metal" code (C) for 8-bit MCUs, mostly for AVRs. In the past, I have used AVR Studio (now Microchip Studio), starting with version 4.18 down to present versions. Tool chain...
I am trying to configure PWMs on the user leds uisng the nucleo-f4329zi board (default preconfigured project) and the visual configuration of the STM32CubeIDE, but for some reason some PWM are not working.My setup for all all PWM (aside from default ...

I am trying to create a 50ms timer using the above reference. The clock is 16MHz, I have a divisor of 16 and have the NVIC enabled (all this is done in cubeMX). I have the following ISR void HAL_LPTIM_AutoReloadMatchCallback(LPTIM_HandleTypeDef *hl...
my read flash reading is bellowing:unsigned short * pAddr = (unsigned short * )0x08004000;unsigned short read_value=0;for(int i=0;i<10;i++){read_value = *(pAddr +i);printf(.....,read_value );}---------------I add read_value to watch window ,however...
When I try to run a project in Release I get this message:No source available for "Reset_Handler() at 0x80007c4"What does this mean ?I do not see it in debug, and BTW I did set the mode to Release...
Hi, i'm using stm32f429 to develop i2c communication, the mcu cannot generate START signal after running a few minutes but the SDA and SCL all high, I add the CR1 register to watch and find the CR1 cannot be modified after calling the bellowing: br...
