代码：
- void TIMER16_IRQHandler(void)
- {
- if(SET == timer_interrupt_flag_get(TIMER16, TIMER_INT_UP)){
- /* clear channel 0 interrupt bit */
- timer_interrupt_flag_clear(TIMER16, TIMER_INT_UP);
- /* toggle selected led */
- g_bsl.tick_1ms++;
- }
- }
- uint32_t get_timer_tick(void)
- {
- return g_bsl.tick_1ms;
- }
- void delay_1ms(uint32_t xms)
- {
- volatile uint32_t tick,diff=xms;
- SET_TICK(tick);
- /*while(GET_DIFF_TICK(tick) < diff){}*/
- while(xms){
- diff = (0x100000+get_timer_tick()-tick)&0xFFFFF ;
- while(diff < 1){
- diff = (0x100000+get_timer_tick()-tick)&0xFFFFF ;
- }
- SET_TICK(tick);
- xms--;
- }
- }
这个是5.0编译器的结果，杠杠的：
这个是6.0的结果，不加volatile直接给你优化了，等级为Oz/Os等都试过了，循环一直出不去，我没辙了，大家救救我吧：
