Hi Mark
Having multiple converters is always a benefit. I have neglected my TV collection in recent years but when I get back to it I can see myself having converters dotted around the place.
Yes it uses the same case as the previous Hedghog's.
It is easy enough to programme. You just need to know a few things about the standard you want to define.
Such as:
The length of front porch, H sync, back porch and broad pulses.
The number of lines, active lines and broad pulses.
The field frequency.
The height of the sync pulses.
I will have a description of the menu done up soon and I will link to it here.
Hi Jeffrey
User interfaces is always a problem but I think it has worked out OK.
Left rotary encoder changes between parameters. Right rotary encoder changes the value.
Pushing the left push button updates the converter, modulators and digital pot with the new values and also saves the values to memory.
There are no nested menus.
I hope Stephen don't mind me saying, I send him a couple of PCB's to test and he has successfully made one up.
