What controller do I need?

Colono

Hi, I have been working with a PLC but I find it very slow programming and processing speed is not the best and I would try with a controller but I have many doubts because I've never used one.

I'm looking for a controller that is able to:
· 2 OUT motor step by step
· 22 or more IN digital
· 2 high Speed IN Digital
· 6 IN analog
· 2 OUT Digital
· Screen
· Timer´s
· Clock in real time
· Memory for Array
· Programming language
And the ability to scale the inputs, outputs and memory…
I also need to connect the controller with an electronic compass and a device that tells the caterpillar robot how far and in what direction is the home position.

What would you recommend me?


I would appreciate any help!!!

Best Regards,
Ariel

I do not know of any off the shelf controllers that would do everything you listed, however if you mean microcontroller by "controller" then you could probably use the propeller to build and program such a system.

If you could add the following to your post you will get a better answer:
- speeds required for the analog and digital inputs
- screen resolution for the display
- size and type (volatile or permanent) of memory for the memory array
- programming language desired

There are many programming languages available including Spin, C, PASM, Forth, and Basic.

I agree with kwinn, a Propeller could do most of what you listed. Some of the requirements listed will require additional components such as the display, analog to digital chip, and compass. Depending on the type of motors you're using you may need a h-bridge circuit for your motors.

I'd suggest starting with a QuickStart board of a Propeller Project board.
