Telnet & TVout Problem?

Projects Programming
1

Hello!

I am working on a project where you connect to the Arduino via telnet, and whatever you type in the telnet client (PuTTY) the text will show up on my TV when you press enter via the TVout library. This is part of a bigger project. Anyway...

When i load the telnet ChatServer example and upload it, i can connect to it just fine and chat with multiple clients on my network.

When i load the TVout library (https://code.google.com/p/arduino-tvout/downloads/detail?name=TVout.zip&can=2&q=) example and run it, i get a display on my TV just fine.

But i noticed right when i add the TVout library #include <TVout.h> to the ChatServer example, i cant connect anymore. I get timed out when i try to. I took the include library code off the example and upleaded it, and connect just fine again. Also when the TVout library is included, i cant cant display text anymore when i program it to. But it still receives some sort of signal because when i upload the script, the TV doesnt have the blue screen anymore.

In the end, i am just trying to display text on my TV through telnet.

I thank you in advance!

EDIT: when i add the:

#include <SPI.h>
#include <Ethernet.h>

library's to the TVout example, it still displays just fine on my TV.

Do you have any common pins on the arduino that are used by the TVout and the ethernet libraries?

No.

TVout library uses pins 8, 9.

Ethenet library uses pins 10, 11, 12, 13

TVout uses interrupts. Possibly they are clashing with the Ethernet card usage.

Is there any way or work around to achieve the end result i said in the first post?

Possibly not, as generating video is very processor intensive. A separate video module might be better. Look up uvga (micro VGA) or tinyvga for some suggestions.

Does this OSD module need a composite input or can it generate it's own. If it generates it's own if no input connected then you can use it to move all of the video heavy lifting off the MCU.
The manual shows a sync select control bit but I'm unsure on it's output with no video. Some OSD equipment at work go tits up when they lose external video and some still work fine.
