一起探討學習

單片機源程序如下:

#include "bsp.h"
#include "stdio.h"
#include "string.h"
#include "ds1307.h"
#include "soft_iic.h"
#define led_1() GPIO_WriteHigh(GPIOD, GPIO_PIN_0)
#define led_0() GPIO_WriteLow(GPIOD, GPIO_PIN_0)
u8 sendData[] = "iic_test";
u8 revData[10];
u8 DeviceData[10];
void main(void)
{
uint8_t rev_dat=0;
uint8_t i=0;
uint8_t t_data=0x11;
uint8_t t_data1=0x00;
uint8_t temp;
BSP_Initializes();
soft_IIC_init();
IIC_Init();
led_0();
timer_delay_s(1);
led_1();
//IIC_Write(0xD0 , 0x07 , &t_data , 1); //用片內IIC寫數據
//IIC_Write(0xD0 , 0x03 , &t_data1 , 1);
iic_write_ds1307(0xD0,0x07,0x13);//control SQ_pin ouuput square wave address 0x07
// 0x10 <--> 1Hz 0x11 <--> 4096Hz 0x12 <--> 8192Hz 0x13 <--> 32.768kHz
//iic_write_ds1307(0xD0,0x02,0xd);
rev_dat = iic_read_ds1307(0xD0,0x01); //read mimutes
while(1)
{
if(rev_dat==35)
{
led_0();
timer_delay_s(1);
led_1();
timer_delay_s(1);
}
}
}
#ifdef USE_FULL_ASSERT
void assert_failed(u8* file, u32 line)
{
/* User can add his own implementation to report the file name and line number,
ex: printf("Wrong parameters value: file %s on line %d\r\n", file, line) */
/* Infinite loop */
while (1)
