Etherten ip being reset after sending DMD data..

[Aussie_Wombat]

Hi all,

Set up manual ip, and send ip to serial

Serial.println(Ethernet.localIP()); //print out the findings.

reports ip is set to my network..(10.1.1.11)

loop through the UDP code and then DMD.drawMarquee code( no DMD output ), and ip still reports as correct when no udp bytes received.(10.1.1.11)

receive bytes over ethernet (UDP) code then DMD displays returned bytes, but then reports ip has been reset to 0.0.0.0

and nothing works again.

used
digitalWrite(10,LOW)
-DMD code-
digitalWrite(10,HIGH)
and the DMD display does not show anything and the ip stays as set (10.1.1.11). Comment out these lines and the DMD displays the text, but the ip gets reset to 0.0.0.0 when the Marquee has finished..?????

Any ideas...

Some output from the serial..

Firstly with setting pin 10 LOW then run the dmd code, then set pin 10 HIGH. There was no output on the DMD at all, but the time between the ip logging was as if it was outputting the marquee..

Code: Select all

Serial output

Now the serial output with the pin 10 LOW/HIGH commented out... The DMD displays the text returned from the UDP....

Code: Select all

IP reports back as 0.0.0.0
Is DMD corrupting the ethernet, by using the same pin as SS??
Can I change the SS pin for the DMD to another pin ( NOT D10 )?
Will try to jumper a new SS pin to the DMDCON, and check it out.....

Hi all,

problem was power supply problems ..

Added the power pack and all is ok now... (not just usb power)

Thanks to everyone that helped

Cheers Dennis
