stm32单片机代码实现功能的问题

帮忙注释一下代码，有点看不明白。

```
uint32 ReadSHT1(uint8 Add)

{

uint32 IResult;

while(1){
SHT1_Start();
SHT1_WriteCommandData(Add);
if(SHT1_Ready()!=0){
SHT1_Reset;
continue;
}
}
else{
SHT1_SendAck();
break;
}
}

void SHT1_WriteCommandData(uint8 bCommand)
{
uint8 i;
Delay();
SHT1SCK_LOW;
Delay();
for(i=0;i<8;i++){
if(bCommand&(0x1<<(7-i)))
SHT1DATA_HIGH;
else
SHT1DATA_Low;
Delay();
SHT1DATA_HIGH;
Delay();
SHT1DATA_Low;
}
P1DIR&=~(1<<1);
}```

uint32 ReadSHT1(uint8 Add) //读SHT1数据

{

uint32 IResult;

while(1){
SHT1_Start(); //开启
SHT1_WriteCommandData(Add); //写设备地址
if(SHT1_Ready()!=0){ //处理中。。。。
SHT1_Reset;
continue; //继续
}
}
else{
SHT1_SendAck(); //等待响应
break;
}
}

void SHT1_WriteCommandData(uint8 bCommand) //向SHT1写入数据
{
uint8 i;
Delay(); //延时
SHT1SCK_LOW; //准备开始
Delay(); //延时
for(i=0;i<8;i++){ //八位数据依次写入
if(bCommand&(0x1<<(7-i)))
SHT1DATA_HIGH; //数据置为高
else
SHT1DATA_Low; //数据置为低
Delay(); //延时
SHT1DATA_HIGH; //数据置为高
Delay(); //延时
SHT1DATA_Low; //数据置为低
}
P1DIR&=~(1<<1);
}```
