How much memory does MiCOS require?

The amount of memory that MiCOS takes depends on the CPU, memory configuration, and depth of the event queue. The following table should serve as a guide:

Processor

Memory

MSP430

460 bytes

M16C

500 bytes

PIC16C5X

350 words

8051

400 bytes

80C188

700 bytes

What language is MiCOS written in?

MiCOS is 100% written in C and is thus easily transferable from one compiler to another.

Do I get the source code with MiCOS?

Yes! MiCOS contains approximately 1,200 lines of code, including its header files.

Are there any royalty payments or other recurring costs for using MiCOS in my application?

No! MiCOS is licensed on a "product line" basis. That is, you can incorporate MiCOS into an unlimited number of devices in binary form within a single embedded product line. One product line is differentiated from another by two primary factors:

  1. A different microprocessor, microcomputer, or microcontroller is used.

  2. If the application changes by more than 20%.

In the event that the product line for which you purchased MiCOS is changed by either 1 or 2 above, you will need to purchase an additional copy of MiCOS for each additional product.

SLTF retains title and ownership to MiCOS.

What do I have to change in MiCOS to make it work in my application?

One thing that MiCOS can't control are all the subtle differences from one compiler to the next. For example, each compiler may have a unique set of pragma statements to control compilation or linking. There may also be compiler-specific memory controls (such as xcode) that you will need to add to MiCOS.

What else comes with MiCOS?

In addition to the source code for MiCOS, you also get a User's Manual on disk (in Word 97 format) and a simple example application. The application will compile and link with Microsoft's Visual C++ version 1.52.

What device drivers come with MiCOS?

MiCOS does not come with any device drivers. MiCOS is a framework for creating independent tasks and states that work together to create a system that's predictable, expandable, and with fewer defects.
