我仿照一个编码器程序改。
源程序为：
`
#include “main.h”
#include “Board.h”
/* Private includes *******************************************************/
/* Private macro **********************************************************/
/* printf function configs to USART2*/
#define DEBUG_USART USART2
#define DIV 167
/* Private typedef ********************************************************/
/* Private variables ******************************************************/
uint16_t encoderNum = 0;
volatile uint32_t tick = 0;
/* Private function prototypes ********************************************/
/* External variables *****************************************************/
/* External functions *****************************************************/
/*!

int main(void)
{

BOARD_LEDInit(LED2);
BOARD_LEDOff(LED2);
/* USART2 Tx PA2 Rx PA3 */
usartConfig.baudRate = 115200;
usartConfig.mode = USART_MODE_TX_RX;

while(1)
{

}
}`
我用的TMR4,PD12,PD13,
程序大约改成这样：
`

TMR_Enable(TMR2);
while(1)
{
BOARD_LEDToggle(LED2);

}`
其中这一句我不知道该怎么改NVIC_EnableIRQRequest(TMR1_UP_TMR10_IRQn, 0, 0);
请问高手如何解决？谢谢
