以下是TMS320的流水灯代码,使用Code Composer Studio编写:
```c
#include <stdio.h>
#include <stdint.h>
#include <stdbool.h>
#include "F2837xD_device.h"
#include "F2837xD_pievect.h"
#define LED1_GPIO_PIN 31
#define LED2_GPIO_PIN 34
#define LED3_GPIO_PIN 37
void initGpio(void)
{
EALLOW;
GpioCtrlRegs.GPAMUX2.all = 0;
GpioCtrlRegs.GPADIR.all |= (1 << LED1_GPIO_PIN) | (1 << LED2_GPIO_PIN) | (1 << LED3_GPIO_PIN);
EDIS;
}
void delay(uint32_t count)
{
uint32_t i;
for (i = 0; i < count; i++) {
asm(" NOP");
}
}
int main(void)
{
uint32_t i;
bool led1_state = false;
bool led2_state = false;
bool led3_state = false;
initGpio();
while (1) {
led1_state = !led1_state;
led2_state = !led2_state;
led3_state = !led3_state;
GpioDataRegs.GPADAT.bit.GPIO31 = led1_state;
GpioDataRegs.GPADAT.bit.GPIO34 = led2_state;
GpioDataRegs.GPADAT.bit.GPIO37 = led3_state;
delay(1000000);
}
}
```
本示例代码假设在TMS320上有三个LED灯,分别连接到GPIO31、GPIO34和GPIO37。代码循环执行,每次循环将三个LED灯的状态翻转,并将新状态写入GPIO寄存器中以控制LED灯的亮灭。在每次循环结束时,程序调用延迟函数延迟一段时间,以使LED灯闪烁。
