I'm looking to use my TV as a display for my 8031 microcontroller circuit. I
know how to take a video signal and modulate it into something the TV can use
(using National's LM1889 or LM2889).
So, now I need a video generator. I need something that can take in character
postion/values or whatever, and generate a video output that I can feed into
the modulator. Need not have color/sound etc.
The only chip I've looked at so far is Intel's 8745 CRT controller. But, this
, as it says, is a CRT controller and doesn't seem to output video readily...
or am I missing something?
Are the other CRT controllers (6845 etc) able to generate a composite video
signal? Is it a composite signal that I need to modulate for the TV????
Please E-Mail me any responses and I will summarize and post the answers...
PS. Can somebody E-Mail me the recent discussion on digitizing voice using
1-bit circuits?
