1. 修改程序，使得led 灯闪烁循环为中速→慢速→快速； 2. 修改程序，使闪烁顺序为d14灯中速闪烁4次→d12慢速闪烁1次→d10 快速闪烁1次，依次循环。 d14gpio口为68，d12gpio口为66，d10gpio口为64。 #include "dsp2833x_device.h" // dsp2833x headerfile include file #include "dsp2833x_examples.h" // dsp2833x examples include file volatile unsigned int timer_int_cnt; // prototype statements for functions found within this file. interrupt void cpu_timer0_isr(void); interrupt void cpu_timer1_isr(void); interrupt void cpu_timer2_isr(void); void gpio
