Logic Help Please

[paulsantangelo]

Hey there:

I'm sort of using an old circuit to drive the LED's and there are ten of them to indicate the wind speed. What I need the logic for is to select the appropriate wind speed to cut another circuit. I figure, I could use a 4066 chip with the CTL connected to the eprom, then when an LED is lit, that potential will then go to a what was a relay STDP, which now will be a set of 4066 and an inverter wired up as a STDP switch. This is where the cutoff switch is.

I'm sure you guys would come up with something better but its what I thought about after reading some of the posts.

The 22v10 sound perfect, the size seems right. Remember I'm still rusty and counters, well lets say I dont get them yet! I have read about them. I was hoping that a counter could have solved my 8 bit problem that you helped me with. But it seems that counters only have 1 output except for the 7 segment counter which has 7 outputs, why couldnt they make an off the shelf 8 bit output? Anyway thats something else. I'm afraid I would need a little more schooling to grasp your double 8 bit output. But the concept is cool, thats for sure.

I think if I read your response, all I would need is two eproms, if I didnt use the one that we worked on anymore.

This chip, how would you make the pins output? Is it more of the address maniplation, or is it something more?

Thanks to you guys for all the help!

Hey:

I found a GAL 22v10 at digikey, part number ATF22v10CQZ-20PC-ND.

Do you think an A-Pro programmer will be able to program it? Acording to the datasheet, any PLD programmer will work. Just what driver do I use? This is an ATMEL chip and I know I have SGS thompson drivers at work, wonder if they are compatible?

More to do at work.

Hi Paul,
Please note the the 22v10 and the multiplexed eprom output are two different solutions for your problem. If you want to use the 22v10 you don't need eproms at all, just 2 22v10 chips.

For the programming of the 22v10, you need to see in your programmer documentation for GAL compatibility. The progamming algorithms are normally different between the different brands.

You lost me on your comments on counters, I can't make the connection with what I understand of your present project.

It might be an idea to summarize the project for us, to let us get a total picture of your inputs, outputs and functionality?

The programmer at work wont program a 22v10, I need the next model up, the Apro +. I did however find someone that does business with our company that does have a programmer that works with this chip. Go figure, huh!!

Sorry about the counter thing, before you suggested using an eprom, I was thinking of using a seven segment decoder. At the time I thought it could produce the binary code I was looking for. That was a mistake.

Now to the programming of the 22v10, Is it the same as the eprom? A 10 bit binary number has a three 3 digit hex value 3FF = 1111111111, so how would you enter the value at the address? If I remember my HEX disk editor days, its entered in reverse, 03FF would be entered FF03. Its a guess, its been a while. Then how do you configure the I/O pins to be output?

Thanks!

Hi Paul,
No, you don't program the 22v10 the same way you do an eprom. I have never bothered to do all the details, but you can compare it to the programming of a large matrix.

If you want you can send me the input -> output tables and I can compile it for you.

Here is the datasheet for the 22v10. Here you can see the basics of the chip. I would suppose that your design can be done with combinatorial logic only. http://pdf.alldatasheet.co.kr/datasheet ... 22V10.html

Thanks Gorgon I really appreciate the help.

I tried my best to keep everything in the correct order, if there is any question please understand the the eprom is wired on my breadboard and outputs exactly as stated below, I used the same format for chip two.

Just a question, now I know you've been doing this for a while, but how would I be able to find out about these chips? Would they be covered in the CMOS cookbook or is there an EPROM book?

Below, the dots are just place holders.

This first one we already worked on..

Again thanks for the help, Is there a method or a madness here? I see what I can find out about programming a matrix!

Thanks agin, you've made me want to learn again...

Gorgon:

I've been looking for programming GAL (Generic Array Logic) chips. I was having no luck and then I ran into this site.

http://www.geocities.com/mwinterhoff/intro.htm

Which told me you need to create a JEDEC file, which seems to contain a kind of assembler langauge.

I was then able to find some files to look at. WOW, Remeber the SAT tests when your were a kid, well I'm not sure when they started, but when you were done, everything took on the shape of a bubble.

Looking at those 1's and 0's was a little perplexing. I figure one thing out, you reserve a space, L320 and fill that space with 1's and 0's in 40 bit sets.

[paulsantangelo]

I found this awsome guide to writing Jedec files. It really does explain a lot!

Hi Paul,
Just for the record. Bit9 on your 10bit output is always '1', so you really doesn't need this in your equation. I suppose that it is off when none of the inputs is active.

I must say that your need for learning is great if you hand-compile a 22v10 jedec file. I'm amazed . I'll try to get some time later this evening and setup your logic in the Palasm program I've got. Just for fun.

[paulsantangelo]

I have a habit of reverse engineering things, ya know, I guess I got caught up in it last night.

Yes, I figure I'll put an on/off switch to Vcc of the 22v10 to turn the whole mechanism off.

Gorgon:

Did I forget to mention thanks!!

Just for fun, huh? Can't wait to see it, in the meantime, will the ATMEL chip do or are you writing this for Lattice?

Thanks again!!

Hey Thanks:

The copy and paste seemed to work, the correct control codes seems to have held in place. I was worried about that.

Just so you know, I grabed from PALASM4 forward, until the final checksum for each file. I think thats what you wanted me to do.

Going over the source code, it looks pretty straight foward. I do have one question.

When choosing combinatorial for the output, does that mean cetain pins will go high based on the input?

I.e. File 2 OP1 = IP0 + IP1 This means when pin 2 goes high, then pin 23 and pin 22 will only go high?

Thanks

paul
