Hi,
I am trying to import IRMP library to my board. I use STM32103VET6 mcu and standart peripheral library. For receiving IR signal i use 38Khz IR receiver, VS1738. MCU clock frequency is 16Mhz, external clock. I use PORTA, PIN_1 of STM32 for receiving port. When i send any IR signal from any remote, i can not get data. My setups are below. Any advise ?
By the way i can not call "IRMP_DATA irmp_data;" in main, compiler gives undecleared error, so i call it outside main.

IRMP_DATA irmp_data;
|

int main (void)
|

{

|

irmp_init();
|
6 |
timer5_init();

|

for (;;)
|
9 |
{
|
10 |
if (irmp_get_data (&irmp_data))
|
11 |
{
|
12 |
// ir signal decoded, do something here...
|
13 |
}
|

}

}
