Drivers in Progress Discussion

[bryanb]

Hey guys. I need to come up with a driver for a Sony Plasma Display. The Sony model number is PFM-42B1. It's one of their professional plasma displays. My problem is that I don't have the RS-232 protocol or commands document. Does anyone have such a document?

Thanks for the help.

A person at this link mentions you have to buy the manual for rs232 programming

Here is an example of a site selling the manual in .pdf format

**Seach google for "PFM42B1 service manual" and you will see other sites offering it for sale...I couldn't find a download for it anywhere

I have half written a driver for the Ultimeter II weather station that you can add to the list.

Also I'm going to start work on a driver to monitor the status of my sewage pumping system..... now that's sure to be a best seller.
I think you can leave that one off the list Vivek.

What system has a seriel interface for it? Mine has discrete outputs hence (one of) the needs for the PLC.

Dont hink you are on your own. My screen is already done and waiting for the inputs - same goes for the pump shed with pump run status, auto/manual status, water pressure, flow, UV Light status and more (I got me a 20 pair instrument cable running into it now - upgraded from a 4 pair).

So does mine, but I am going to put a small dedicated micro on it to watch the activity and turn it into a serial stream, probably RS485 as I already have a heap of devices that I made and never used, that I can reprogram for the job.

An entire heap? Some that you might want to pawn off?

Well, 10, if that's a heap.

I'm not sure what they could do for you, what did you have in mind?

Just by way of interest, I was originally going to stick these things in most rooms around the house to allow a little local CQC control. with a bit of simple text feedback. This particular version has a temp sensor in it, so it was going to be my room by room thermostat. It also responds to IR so you can cause it to send stuff from accross the room.

Here's a pic of the watching TV assembly line.

Well, actually... exactly that.

Communicate with the "master house computer" and report temperature in the rooms, display short messages, and perhaps allow a small amount of text-based menuing.

To start, current local temp and central (i.e. CQC-based) time displayed in each room and reported to the monitoring computer, without looking ugly or costing a fortune.

I was looking into 1-wire based options, (and my wife would, I'm sure, like to see the cat-5 strung to four sensors around the house be made to disappear -- we were monitoring and logging prior to replacing the HVAC, and are now seeing how effective the changes have been) but the complexity of making messages appear on an LCD over 1-wire are a bit daunting, as is the fabrication of the device itself.

Are those connection jacks or push-buttons right under the display? I don't forsee the need to plug anything into them.

Oh and, my 6-year-olds room is being redone in a space them, so I'm going to build him some sort of panel like in the modl of the Gemini capsule that he likes to play with at the Science Center. Won't do much, coloured lights, a count-down, maybe a .wma file of a rocket lauch or something. Anyone know where I can buy an artificial horizon and altimeter that can be controlled by random bits of electricity....

Ever notice that this gets out-of-hand so easily?

[rhamer]

They are 4 push buttons.

The concept was to use them as soft keys with the functions labeled on the bottom row of the LCD.

The lower part of the panel houses the IR receiver a programming jack (to avoid removing them from the wall to update the firmware) and the temp sensor.

Some more pics just for fun.




This one had a second board that added more memory, and a clock.

Looks very cool. Did you finish the software? Where did you get the mounts/panels? That's one of my frustrations.

Oh Beautiful Hardware ;-))......What micro you using Rohan ????

I see your reading Barry Gordan,s ir info..... was that from Home Automator Mag...??? Great little mag shame its still not around ...lots of diy stuff......
