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
以下是修改后的程序示例，实现了您要求的 LED 灯闪烁循环和顺序： ```c #include "dsp2833x_device.h" // dsp2833x headerfile include file #include "dsp2833x_examples.h" // dsp2833x examples include file volatile unsigned int timer_int_cnt; volatile unsigned int led_state = 0; // 用于跟踪当前的 LED 状态 volatile unsigned int led_sequence = 0; // 用于跟踪当前的闪烁序列 // 定义不同速度的闪烁间隔 #define MEDIUM_SPEED_INTERVAL 500000 #define SLOW_SPEED_INTERVAL 1000000 #define FAST_SPEED_INTERVAL 100000 // 定义 LED 对应的 GPIO 口 #define LED_D14_GPIO 68 #define LED_D12_GPIO 66 #define LED_D10_GPIO 64 interrupt void cpu_timer0_isr(void) { timer_int_cnt++; switch(led_sequence) { case 0: // D14 中速闪烁 4 次 if(timer_int_cnt >= MEDIUM_SPEED_INTERVAL) { GPIO_toggle(LED_D14_GPIO); if(++led_state == 8) // 因为闪烁 4 次，所以状态数为 8 { led_state = 0; led_sequence = 1; } timer_int_cnt = 0; } break; case 1: // D12 慢速闪烁 1 次 if(timer_int_cnt >= SLOW_SPEED_INTERVAL) { GPIO_toggle(LED_D12_GPIO); led_sequence = 2; timer_int_cnt = 0; } break; case 2: // D10 快速闪烁 1 次 if(timer_int_cnt >= FAST_SPEED_INTERVAL) { GPIO_toggle(LED_D10_GPIO); led_sequence = 0; timer_int_cnt = 0; } break; } // 清除中断标志 PieCtrlRegs.PIEACK.all = PIEACK_GROUP1; } void main() { // 初始化系统 InitSysCtrl(); // 初始化 GPIO EALLOW; GpioCtrlRegs.GPAMUX1.bit.GPIO68 = 0; // 设置为 GPIO 功能 GpioCtrlRegs.GPADIR.bit.GPIO68 = 1; // 输出方向 GpioCtrlRegs.GPAMUX1.bit.GPIO66 = 0; GpioCtrlRegs.GPADIR.bit.GPIO66 = 1; GpioCtrlRegs.GPAMUX1.bit.GPIO64 = 0; GpioCtrlRegs.GPADIR.bit.GPIO64 = 1; EDIS; // 初始化定时器 0 InitCpuTimers(); ConfigCpuTimer(&CpuTimer0, 150, 100000); // 配置定时器 0 的周期和分频 // 使能定时器 0 中断 PieCtrlRegs.PIEIER1.bit.INTx7 = 1; IER |= M_INT1; // 启动定时器 0 StartCpuTimer0(); while(1) { // 主循环可以添加其他非关键操作 } } ``` 上述代码仅为示例，您可能需要根据您的实际硬件和开发环境进行适当的调整和修改。 [2024-10-20 21:13:53 | AI写代码神器 | 865点数解答]
