View Full Version : DEBUG Output Directly To A Monitor

For a variety of reasons, I like to·watch what's happening in my jumble of Stamps via DEBUG statements. However, I'd like to achieve this without a laptop/pc being used.

What do I need to do, so I can see DEBUG directly on my LCD screen? Maybe there's·a device I can put between the Stamp and the LCD, to converts the output.

All suggestions gratefully recieved, even if only to say it's not possible....

Thanks, John Burrow

If you have an NTSC video monitor (CRT or LCD) handy, you can use the Propeller Backpack (http://www.parallax.com/StoreSearchResults/tabid/768/txtSearch/28327/List/0/SortField/4/ProductID/602/Default.aspx) module to get your DEBUG (in this case, SEROUT) output on the screen.

It depends on your LCD screen. If you have a TV video-based LCD, you could use a Propeller Backpack to act as a serial to video display. Look at the Backpack's webstore page for the documentation. If your LCD takes VGA video, you could use a Propeller Demo Board as a VGA text display. There are several threads on the use of two Propellers as a Z80 computer with one of them acting as a terminal using a VGA display. The terminal program could be used with your Stamps just as well. You'd need an RS232 level converter like the MAX3232 since the Stamps provide RS232-like voltages on the DEBUG / programming pins.
