Hi guys,I have got a display as above from edi displays( http://www.electronicdisplays.com/products-detail.asp?productNumber=21) . I am using an arduino uno and a rs232 shield from dfrobot. I got a test program from the net and modified it slightly, I wanted the display to update the time just over every second to test it.
void setup()
{
Serial.begin(1200);
}
void loop()
{
unsigned int raceTime;
raceTime =millis();
{
Serial.println(raceTime/1000.00);
delay (1023);
}
}
the transmission protocol for the display is 1200 Baud,8 data bits,1 stop bit,no parity.
The display works the first time giving me the seconds and hundredths as i wanted, but as the program cycles it stays with the first time displayed.
If I open serial monitor then I can see the times being updated as I want, but it doesn't happen on the external diplay.
I'm new to arduino so any help would be greatly appreciated, hopefully its just something silly.
Thanks in advance.
