freecale FAE give me a example about MKE02Z lately.but i debug unsuccessful for<<UART_demo>> and <<PIT_demo>>. it's enter into interrupt but not turn out. result not run all proceduce .does anyone know the answer??

不久前飞思卡尔的技术支持给我了一个关于MKE02Z的范例，但是我调试<<UART_demo>> 和<<PIT_demo>>的时候并不成功，他们都能进入中断但是出不来，导致所有的程序都卡死了。有人知道答案吗？？？

#include "common.h"

#include "rtc.h"

#include "uart.h"

int main (void);

void RTC_Task(void);

/******************************************************************************

* Global functions

******************************************************************************/

void UART_rx(int8 ch)

{

UART1_send_byte(ch);

RED_Toggle();

}

/********************************************************************/

int main (void)

{

LED0_Init();

printf("\nRunning the Uart_demo project.\n");

#ifdef UART_INT

/* uart interrupt mode */

UART_set_rx_handler(UART_rx);

enable_UART1_int();

printf_int("\nhello world\n");

#endif

while(1)

{

}

Hi 宝荣，

请问您的问题解决了吗？从代码中，初步确定是因为没有使能UART 的时钟。

如果仍有问题，欢迎交流。

我都忘了是那个事情了，倒不是UART不能使能，需要将中断函数与中断向量关联起来，在isr.h里面,把UART中断和向量关联起来。
