怎么用PIC12F1572与TSOP2438接收机模块建立一个IR接收机

你好，所以我正在用PIC12F1572与TSOP2438接收机模块建立一个IR接收机。这个项目的目的是通过遥控接收数据，并通过UART发送给PC。我已经完成了代码，我正在测试它，我可以通过UART发送正常值，但是某处是错误的，这样我就不能接收到关于遥控器命令的十六进制值了。谁能看到我的代码并告诉我哪里出错了？感谢是我的密码

    Hello,
So I  am building an IR Receiver with PIC12F1572 with receiver module TSOP2438 My objective of this project is to receive a data by remote control and send it to PC via UART.. I have done the code and I am testing it I can send the normal value through the UART but Somewhere is wrong so that I can not receive the hex values regarding the commands of remote control Can anyone see my code and tell where I am going wrong?

Thanks
Here is my code

void main(void)
{
OSCILLATOR_Initialize(); // 0x78 for Fosc = 16Mhz
PIN_MANAGER_Initialize(); //All port pins Digital and input
EUSART_Initialize();
INTCONbits.IOCIF = 0; // Interrupt on-change Flag
INTCONbits.PEIE = 1; //SEt Peripheral Interrupt
INTCONbits.GIE = 1; //Set Global Interrupt
//while(!OSCSTATbits.HFIOFS); //Check here or wait here to OSC stable/ 0.5% accuracy

TRISAbits.TRISA2 = 1; //Configure R1 as input

// uint16_t Input_buffer [20];

EUSART_Write(0x40); // 0x40 = @ some flag


while(1)
{
count = 0;
//while((IR_PIN)); //IR_PIN receives an IR signal its output pin goes from logic 1 to logic 0
//which causes the microcontroller to start reading the IR signal using the function. decode()
EUSART_Write(0x41);
//while(IR_PIN);

if(Decode()) //check if RC5 decoding- new data is arrived
{

EUSART_Write(0x42);

toggle_bit = bit_test(IR_Code, 11);
address = (IR_Code >> 6) & 0x1F;
command = IR_Code & 0x3F;

EUSART_Write(toggle_bit);
EUSART_Write(address);
EUSART_Write(command);

EUSART_Write(0x43);


}
}
}

/*----------*/
uint8_t Measure_space()
{
TMR0_Initialize();

while(IR_PIN && (count < 2000))
count = TMR0_ReadTimer(); //Read timer value and store it in count value
if((count > 1999) || (count < 700))
return 0; //0 = If width is out of range
if(count > 1200)
return 1; //1 = If width is long
else
return 2; //2 = If the width is short
}

uint8_t Decode()
{
uint8_t i = 0, check;
mid1:
check = Measure_Pulse();
if(check == 0)
return FALSE;
bit_set(IR_Code, 13 - i);
i++;

if(i > 13)
return TRUE;

if(check == 1)
goto mid0;
else
goto start1;

mid0:
check = Measure_space();
if((check == 0) && (i != 13))

return FALSE;

bit_clear(IR_Code, 13 - i);
i++;

if(i > 13) return TRUE;

if(check == 1)
goto mid1;
else
goto start0;

start1:
check = Measure_space();
if(check != 2)
return FALSE;
goto mid1;
start0:
check = Measure_Pulse();
if(check != 2)
return FALSE;
goto mid0;
