C++ (Cpp) send_MM_cmd Examples

Example #1

File: test.c Project: avnishks/pratham

int main(void)
{
  _delay_ms(1000);
  char buf[10], a = 0;
  
  init_UART_MM();
  send_MM_cmd("Hi\r", 0);
  
  init_SPI();
  
  Current_state.gps.x = 1;
  Current_state.gps.y = 2;
  Current_state.gps.z = 3;
  
  while(1)
  {
    _delay_ms(2000);
    a++;
    sprintf(buf, "sent %d", a);
    send_MM_cmd(buf, 0);
    slave_send (HM_DATA, (char *)&Current_state, sizeof (struct state));
  }
  
  return 0;
}
