when program started interrupt is called but its read only one character and repeatedly read same character.most time getting garbage value.
RXNE Flag also set. my application is to handle data send by ATMEGA16 in while condition.
program:
void USART2_IRQHandler(void)
{
//Local variable
unsigned char data=0,i=0;
unsigned char TEMP[5];
if(USART_GetITStatus(USART2, USART_IT_RXNE) != RESET)
{
data = USART2->DR;
if(i<5)
{
TEMP[i]=data;
i++;
}
}
}
