为了实现您要求的功能,我们需要对现有的代码进行一些修改。首先,我们要确保我们有正确的GPIO配置来控制D14、D12和D10的LED灯。然后,我们将使用CPU定时器来控制不同速度的闪烁模式。 以下是修改后的代码示例: ```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 state = 0; // 用于切换不同的状态 volatile unsigned int blink_count = 0; // 用于计数当前状态下的闪烁次数 // 定义LED对应的GPIO口 #define LED_D14_GPIO 68 #define LED_D12_GPIO 66 #define LED_D10_GPIO 64 // 定义不同的闪烁速度(单位:毫秒) #define MEDIUM_SPEED 500 #define SLOW_SPEED 1000 #define FAST_SPEED 250 // 原型声明 interrupt void cpu_timer0_isr(void); void gpio_setup(void); void led_toggle(unsigned int gpio); int main(void) { // 初始化系统控制 InitSysCtrl(); // 配置GPIO gpio_setup(); // 配置CPU定时器0 CpuTimer0Regs.TCR.all = 0x4000; // 使能定时器0,预分频器=1 CpuTimer0Regs.PRD.all = (MEDIUM_SPEED * 10); // 设置周期为500ms(假设系统时钟为100MHz) // 使能定时器0中断 PieCtrlRegs.PIEIER1.bit.INTx7 = 1; IER |= M_INT1; EINT; // 启动定时器0 CpuTimer0Regs.TCR.bit.TSS = 0; // 主循环 while(1) { // 主循环中可以添加其他任务 } } interrupt void cpu_timer0_isr(void) { // 清除定时器0中断标志 CpuTimer0Regs.TCR.bit.TIF = 1; // 根据当前状态切换LED switch(state) { case 0: // D14中速闪烁 led_toggle(LED_D14_GPIO); blink_count++; if(blink_count >= 4) // 中速闪烁4次后进入下一个状态 { state = 1; blink_count = 0; CpuTimer0Regs.PRD.all = (SLOW_SPEED * 10); // 调整为慢速 } break; case 1: // D12慢速闪烁 led_toggle(LED_D12_GPIO); blink_count++; if(blink_count >= 1) // 慢速闪烁1次后进入下一个状态 { state = 2; blink_count = 0; CpuTimer0Regs.PRD.all = (FAST_SPEED * 10); // 调整为快速 } break; case 2: // D10快速闪烁 led_toggle(LED_D10_GPIO); blink_count++; if(blink_count >= 1) // 快速闪烁1次后回到第一个状态 { state = 0; blink_count = 0; CpuTimer0Regs.PRD.all = (MEDIUM_SPEED * 10); // 调整回中速 } break; } } void gpio_setup(void) { // 配置D14 LED GPIO GpioCtrlRegs.GPAMUX1.bit.GPIO68 = 0; // 设置为GPIO功能 GpioCtrlRegs.GPADIR.bit.GPIO68 = 1; // 设置为输出 GpioDataRegs.GPATOGGLE.bit.GPIO68 = 0; // 关闭LED // 配置D12 LED GPIO GpioCtrlRegs.GPAMUX1.bit.GPIO66 = 0; // 设置为GPIO功能 GpioCtrlRegs.GPADIR.bit.GPIO66 = 1; // 设置为输出 GpioDataRegs.GPATOGGLE.bit.GPIO66 = 0; // 关闭LED // 配置D10 LED GPIO GpioCtrlRegs.GPAMUX1.bit.GPIO64 = 0; // 设置为GPIO功能 GpioCtrlRegs.GPADIR.bit.GPIO64 = 1; // 设置为输出 GpioDataRegs.GPATOGGLE.bit.GPIO64 = 0; // 关闭LED } void led_toggle(unsigned int gpio) { GpioDataRegs.GPATOGGLE.bit[gpio] ^= 1; // 切换LED状态 } ``` 解释 1. GPIO配置: - `gpio_setup`函数配置了三个LED的GPIO引脚,设置为输出模式,并初始关闭所有LED。 2. 定时器配置: - 使用`CpuTimer0`来控制LED的闪烁频率。定时器的周期根据当前的状态(中速、慢速或快速)进行调整。 3. 状态机: - 使用一个状态变量`state`来跟踪当前的闪烁模式。每次定时器中断触发时,根据当前状态切换相应的LED,并更新状态。 - `blink_count`用于计数当前状态下的闪烁次数,当达到预定次数时,切换到下一个状态。 4. LED切换: - `led_toggle`函数用于切换指定GPIO引脚上的LED状态。 注意事项 - 假设系统时钟为100MHz,因此定时器的周期设置为毫秒值乘以10。如果您的系统时钟不同,请相应调整定时器的周期值。 - 请确保您的硬件支持这些GPIO引脚,并且正确连接了LED灯。 [2024-10-20 21:14:18 | AI写代码神器 | 1309点数解答]
