DIY Controller (Atmel based)

Hey Kwirky if you have any problems with the code let me know....What language are you gonna program in???

I can program with C of coarse and I'm not bad with assembly!

I'll be using C through the gcc/atmel compiler. Assembly would be required for something of extreme performance but it's not like I'm doing frequency generation or the likes. I shouldn't have problems with C. It'll more or less be problems with the poorly documented atmel library for C that I forsee. But like I said i'm not doing anything real complex.

One thing I don't know is how to make a serializing circuit. I understand the programming but how the transistors would go together to "unserialize" the data later is a bit beyond me. It's the electronics that I'm learning as I go.

I got me some "8 bit parallel serial shift registers"

They're so I can use like 3 pins for 8 pins worth of traffit. mainly for the LCD screen/s.

I got all the 10 pin wire and ends too and a cheap little 500ma power supply. I'll be getting the serial cable tomorrow hopefully then start playing with them on friday.

Yup. As an electrician myself, I am very interested in your outcome. Ive been thinking of trying a old PLC5 from work to controll stuff, but the physical size of the chassis are just to huge. Now if only I could get a little SLC processor..... HAHAHA

So how is this progressing? Are you ready to mass produce yet?

[BC564]

you could alway use a micrologix PLC......

[Robw]

How is this project going? There hasn't been any updates in several months? Do you have any source code for perusal?

[spreerider]

I have access to a bunch of melsec A1S PLCs and have started building a controller out of one, the chassis size is a bit large but compared to all the recepticles and contactors that will be in the case the PLC isnt that bad.

haha I've been SO busy with other stuff the hardware's sat on the shelf. My real nice workspace in the basement was taken down. Also I've been busy helping my fiance with the business (along with my job at golds) therefore I haven't been able to continue with it lately.

I have to say I'm spoiled developing on something high level with tons of framework like c# and dot.net. The learning curve of programming in the Atmel's version of C is VERY steep compared to what I'm used to.

Also the text screen I picked up has ZERO documentation. It's a 20x4 screen and you have to overflow it's registers to use the extra characters (standard is 16x2). That's all I figured out so far.

I got the controller switching the opto-relays on and off but as for the screen it reached a stand still.

But it's indefinate when I'll be able to continue with the project.
