i use NUCLEO - F767ZI and test a simple code as followint sum(int a,int b){   return a+b; }   int main(void){   int dly;   __enable_irq(); SysTick_Config(100000); NVIC_EnableIRQ(SysTick_IRQn); dly = sum(1,3); return 0...

Posted on July 19, 2017 at 04:51hi,i initialize and set rtc as followint rtcInit(void){    RCC->APB1ENR1 |= RCC_APB1ENR1_PWREN;    // enable PWR clock    PWR->CR1 |= 0x00000100; // disable BD write protect    while(0 == (PWR->CR1 & 0x00000100));    ...

Posted on March 15, 2017 at 07:30hi,I want use LPTIM1 and select clock source is LSE.when i enable LSE use code auto-gen from stm32cubemx,but LSERDY can't assert,the external OSC is work normal.init code like as:void SystemClock_Config(void){  RCC_O...

Posted on March 09, 2017 at 04:08HI,i found that some peripheral can select clock source  by  change RCC_CCIPR.but both ADC and CLK48M,default clock source is ''No clock selected'',it can work normal also.why?
