Posted on April 13, 2012 at 14:23I have tried both of these ideas, both by themself and together at the same time to no avail.
I found some more ''interesting'' behaviour, if i remove a loop which waits for the Led1FlashCount to get to 0 the hard fault handler is not triggered. The Led1FlashCount is decremented in the Timer 3 Interrupt. This line is commented in the code below.
int main(void)
{
RCC_Configuration();
NVIC_Configuration();
Timer3_Init();
Led1_Init();
USBMassStorage_Init();
uint8_t status = 0;
while (1)
{
if(status == 0)
{
status = 1;
Led1Flash(20, 200);
}
else if(status == 1)
{
status = 2;
Led1Flash(5, 600);
}
else
{
status = 0;
Led1Flash(2, 1800);
}
//This code causes the application to crash???
while(Led1FlashCount > 0)
{
}
}
}
this is the Timer 3 interrupt code
void TIM3_IRQHandler(void)
{
if(TIM_GetITStatus(TIM3, TIM_IT_Update) != RESET)
{
TIM_ClearITPendingBit(TIM3, TIM_IT_Update);
if(WaitCounter > 0)
{
WaitCounter--;
}
if(Led1FlashCount > 0)
{
if(Led1DurationCount > 0)
{
Led1DurationCount--;
}
if(Led1State == 1
&& Led1DurationCount < Led1Duraion / 2)
{
Led1Off();
}
if(Led1DurationCount == 0)
{
Led1FlashCount--;
if(Led1FlashCount > 0)
{
Led1DurationCount = Led1Duraion;
Led1On();
}
else
{
Led1Off();
}
}
}
disk_timerproc();
}
}
