On Screen Displays?

The reason the maxim chip was going to get expensive for me was
I was planning to use 3 of them,
one on each of the RGB signals,
so I should have got colour, but at a cost.

It is possible to get dedicated chip, but you will need much more hardware.
Old CRT monitors have color OSD chip, which is I2C driven (forgot model, but you can find it with ease). The main issue is that it operates with RGB data. So to use it with your video in video out, you will need to "disassemble" your video signal, add OSD and "assemble". The above mentioned maxim chip passes color without problems, I've been using it with PICBASIC (adapted basic stamp code)

Hi All!
So far all I have found is the STV5730A chip. Mainly my Google search abilities seemed to have become limited. Blackboxcamera did have a unit some time ago. I did call STMicro and contacted Blackboxcamera and struck out. Someone must have something on this chip?

Best, Ed

hello
sure I have that you need in term of STV5730A .. let me search in my junck ...
if I forget to come back .. ring me F1CHF at FREE dot FR

Hi F1CHF,
WB6NSN (Ed/Ramius) here! Thank you and I did by some as well as an SO28 to DIP adapter board. Did you have any luck with you code? How about with your antenna pointing system? I read a very old post of yours and if you did not get your antenna system to work then you might want to use the old trick of using a pot with a fixed resistor across it!

hi WB6NSN
I didn't understand if you have done "something" using this old STV5730
for my antenna position, I do not remenber, it was for our TVA repeater, but now it is dead !
the house where the repeater was installed is down ...
I see this article .. inscrustation in French means OSD ..
have a look http://f5mna.free.fr/Arduino.htm
good luck

Hi Francois!
Actually I have not done anything yet, still researching the options. In my previous post I just wanted you to know that I was also an "amateur radio" or "ham" radio operator also! The link you posted (Thank you) is for the MAX7456 which is a common white text only chip design and not a color text chip like the STV5730A. The STV5730A had, at one time, been considered "end of life" and the demand for the chip caused the manufacturer to start producing them again so they are not difficult to find anymore. I was hoping to find a PIC program for the STV5730 rather than having to "re-invent the wheel". Sorry about your repeater I miss my as well. If you find any programs for the STV5730 please let me know.

Thanks, Ed
