在GCC AVR里,#include <stdint.h>用来定义了数据类型。
如：
typedef signed char int8_t
typedef unsigned char uint8_t
typedef signed int int16_t
typedef unsigned uint16_t
typedef signed long int int32_t
typedef unsigned long int uint32_t
所以再用时就不用定义了，直接用就行：
程序就是使LED循环地点亮.

- #define F_CPU 8000000UL
- #include <avr/io.h>
- #include <util/delay.h>
- #include <stdint.h>
- int main(void)
- {
- int8_t b=0,direction=0;
- DDRA=0xFF;
- while(1)
- {
- if(direction==0)
- PORTA = 0x01<<b;
- else
- PORTA = 0x80 >>b;
- if(++b==8)
- {
- b=0;
- direction = !direction;
- }
- _delay_ms(60);
- }
- }
