YAPPish (home-made or very cheap) Seatalk display?

Decided I'm not up to making such modifications, and have ordered the parts as specified, to be assembled and programmed as-is. Then maybe I can make progressive changes from a working system

I'll have a go at merging the Seatalk repeater YAPP with my text display driver, but like you, it's not easy to test at home.

I bought a broken Raymarine TriData unit on eBay, it just had a broken switch. Now I've got a handy test device.

Thanks, but there's no need. I already have the screen you used for the repeater project - it's smaller than I had thought, in fact no bigger than the text display, so I might as well use it as-is. Once it's working as designed I might have a go at modifying the display code to get my six pieces of data in bigger text, rather than the whole list. Would also be nice to be able to adjust the brightness for night time, if the hardware supports that - perhaps a use for the vestigial touchscreen code that's in the repeater project but apparently not being used.

Cheers,

I've nearly done it now so I'll publish it when its tested anyway. There is vestigial touch code in there - it was cut down from another project. The touch values are not very repeatable. The best way is to take 10 readings, sort them, find the middle 2, then average these 2. Strange, but it works best. I also have some touch screen calibration code I can send.

Don't think there is any backlight control, but you can set the background to black and the text to a dark grey which would have the same effect.

I wasn't even going to look at touch positions. Just cycle through three or four different brightnesses each time a touch happened anywhere on the display

That will be easier. Code supplied will do that.
