dear e2e ,
I am trying to communicate with GSM module and controller through UART(SCI). I am sending data to module in polling and Receiving data in interrupt method. While receiving data, some data is missing.
I configured UART to 115200 baud rate , 1 start bit , 1 stop bit and 8 bit data . I enable rx int mode in sci tab of halcogen.
Below is the code for interrupt service routine.
extern unsigned char rx_str[500];
unsigned char rx_k = 0;
void sciNotification(sciBASE_t *sci, uint32 flags)
{
sciReceive(sciREG1, 50 , rx_str);
rx_k++;
}
Can you help me to resolve this problem?
