555 Timer with input/triggered from Microcontroller

You are expecting a bit much with 8 + 8 + 8 requirements.
The simplest way to orgainse this is .asm
It's the only way you are going to fix a problem if one arises.
Already, everyone is telling you complex ways to tackle the problem.

What makes you say this is too much? To check 8 inputs and adjust 8 outputs in 1mS is trivial, doing it in 10mS is an absolute doddle.

BTW, I didn't understand what the third 8 was.

@colin55,
It's 8 monitored inputs (PIR sensors) and 8 outputs (LED(s)).
I'm not aware of how to do the .asm. However, I'm looking for the simplest way to do this if it can be achieved (by software/programming). My main concern was having the Stamp perform perform multiple functions (sense two - three PIRs, while keeping the load(s) within the timed parameters)).
 
You need 3 ports - one has to have 8 A/D's or one A/D and a select button and LEDs
I only work with PIC's
 
I'm a little confused about the ports you mention. I don't have a select button and LEDs.
Was this post meant for someone else?
 
I don't understand the entire question, but I will have inputs from the PIRs (8 input pins) and outputs for the 8 LED lights (8 output pins).
 
What happened to the 555 and the variable-timed outputs????????????????????

Now it's just 8 inputs and 8 LEDs that turn on for a fixed time of 10 seconds.

Why didn't you say this in the first place, instead of beating around the bush, wanting all sorts of time-consuming programming challenges.

You just need a PIC16F628 and 100 lines of code.

He/She did say this in the first place. It was always 8 in and 8 out. It was you that said it was 8+8+8 which I never understood. Plus, you somehow made it analogue!!

Stop complicating things and then complaining when the OP gets confused.

I'm going to be quiet now because otherwise I may get banned.

Mike.
 
@Mike, thanks for the response.
@colin55, I'm just trying to gain some knowledge and/or solution here. No need to get a little upset. As Mike stated, I listed out what I thought were all the requirements and other asked questions.
Please I don't know all of what you all know, so please be patient.
Thanks
