以下是LM3S2D93的初始化代码示例,你可以根据自己的需求进行调整:
```c
#include "inc/lm3s2d93.h"
void init(void)
{
/* Enable the GPIO port that is used for the on-board LED. */
SYSCTL_RCGC2_R = SYSCTL_RCGC2_GPIOF;
/* Do a dummy read to insert a few cycles after enabling the peripheral. */
volatile uint32_t delay = SYSCTL_RCGC2_R;
/* Set the direction as output (PF1). */
GPIO_PORTF_DIR_R = 0x02;
/* Enable the GPIO pins for digital function (PF0 and PF1). */
GPIO_PORTF_DEN_R = 0x03;
}
int main(void)
{
/* Initialize the system. */
init();
/* Turn on the LED. */
GPIO_PORTF_DATA_R |= 0x02;
/* Loop forever. */
while (1)
{
}
}
```
以上代码中,我们启用了GPIO端口F并将其设置为输出,然后打开了PF1引脚的LED灯。你可以根据需要更改GPIO端口和引脚。
