HD1024 serial input from Arduino through USB

Hi.

I have an Arduino DUE that prints on Serial ( Serial.println() ) a number.

I setted up the serial input event on port 1 for trigger the start of a video but nothing happens.

Baud is set on 115200 on boh devices.

What's wrong?

  For troubleshooting, try using Serial.print instead of Serial.println

  https://www.arduino.cc/reference/en/language/functions/communication/serial/print/

  In your case the BrightSign is waiting for an integer, so:

  Serial.print(i, DEC);

  I tried both Serial.print(i) than Serial.print(i, DEC) but it doesn't work. Neither Serial.println(i, DEC).

   

  Mmh.. what's wrong..

  But is it possible to connect Arduino directly to brightsign with the USB cable or I need the adaptor USB/Serial Jack 3.5mm??

  If you're using Serial input on the BrightSign, you'll need to use the 3.5mm RS232 input.  If you don't have a DB9-3.5mm cable, something like this is what you need:

  ALTERNATIVES:

  However, if you only have up to eight combinations, you could use the GPIO.  How many sensors do you have?

  As a second alternative for your Arduino, you could also get the Ethernet shield and use UDP commands.

  Ok now it's clear!

  Thank you

   

  In the meantime I solved with Ethernet and UDP!

  Excellent!   Glad to hear it!

  Good luck with your project.
