Part 2 -- The Code

[KE4EST]

Okay guys discussion is open.

 

[Magic Static]

I haven't reviewed all the material yet, but there was one thing I was curious about. Are touch screens made with a common interface like LCD displays. Last year I bought a weather sensor with two touch screen displays. Both of these displays failed. They won't boot up. They show the boot screen and freeze. I'm thinking the screens still work and I might be able to repurpose them for this project. They are a larger 7" screen though.

OK a little research and I see what's up. nevermind

 

[KE4EST]

There are a ton of different interfaces and different touch chip-sets also. I have a nice screen that I can use as a screen just fine, but not the touch part. No one has wrote any C code library for it. At least not to work with my setup. Lots of projects though, that I don't need touch.

 

[arlo]

Could I try to revive this thread? I've been brainstorming so much my head hurts.
Since Brian discontinued the ASC-1 dish movers are sparse out there.
Ones which accept a DISEqC go-to message from a receiver.
I've contacted NXP for info. implementing one of their dev. boards to make a mover using an H Bridge.
Software licensing is not cheap. And with my limited programming knowledge plus the learning curve to expand on it.
Time would run out. Contacted a few others also.

I see a closed thread here that pertained to troubles getting a reliable clean data stream.
I found quite a few circuits to pull, filter the 22 kHz frequency, and provide a clean pulse train out.
I actually built a crude filter and comparator and fed it into my DSO and was able to "kind of" decode and pick out the go-to code. It was made from parts I had laying around and stuffed in a breadboard.

Follow me? My Arduino usage is honestly to use the serial port and console to flash firmware and debug things like routers and such. I've just tippy-toed into the programming.
How to wait for and store a DISEqC data stream. Read the data stream. Find the go-to memory location. BUILD the memory and store encoder count position locations. And command the H Bridge to send the dish to the right place.
Step by step. Right? And somehow stuff in a display, maybe read a remote control.
Overwhelming.

As I do my daily search on eBay I see a lot of the commercial dish movers such and those made by Research Concepts. But they are keyboard entry. Big and robust and made to last. Affordable on some days.
But. They do not accept a DISEqC signal.
They do have a RS-422 interface and a manual with console commands.
Other dish movers I see have dedicated software that communicates over a data bus.
They all have stored positions in NVRAM. The all have a go-to command.
No DISEqC interfaces.

I need a translator. A protocol converter.
An Arduino or Raspberry pi that just sits there waiting for a data stream from my receiver.
Store the message in a buffer. Read the buffer. Pick out the go-to command data.
And send a compatible data stream out to the RS-422 interface on the dish mover.

Such a thing must exist. Perhaps not for satellite dish "language". But adaptable?
Does this sound immediately like a far fetched idea?
Is/has something like this been done with an Arduino or pi?
