Posted on April 13, 2018 at 18:26Hi, i want to use internal crystal. I'did configrations via cube mx however it did not worked. I want to test it with blink led. As you see my code;
I don't know where i am wrong ?
Thanks a lot
/********************************************
int main( void )
{
bool isMaster = true;
uint8_t i;
HAL_Init( );
SystemClock_Config( );
MX_GPIO_Init();
//*
HAL_GPIO_WritePin(GPIOB, GPIO_PIN_9, GPIO_PIN_SET); //led pin
delay_main=0;
while(delay_main<100);
HAL_GPIO_WritePin(GPIOB, GPIO_PIN_9, GPIO_PIN_RESET);
//*
DBG_Init( );
HW_Init( );

TimerInit(&timerLed, OnledEvent);
TimerSetValue( &timerLed, LED_PERIOD_MS);
TimerStart(&timerLed );
