ADC cann't enter interrupt

Hi,

why i cann't enter interrupt. @ SC1A's AIEN=1&coco=1

void ADC0_IRQHandler(void)
{
int i=0;
i++;
print(welcomeStr);
}
void ADC1_IRQHandler(void)
{
int i=0;
i++;
print(welcomeStr);
}

Hi wang qiang ,

Which detail kinetis chip are you are using now?

Please tell me your kinetis chip part number, then I can help you to check the details.

When you want to enable the ADC interrupt, you need to configure the ADC IRQ, enable it, and enable the global interrupt.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Kerry
