uEZ Operating Systems Abstraction Layer (OSAL)

The selection of an RTOS can be one of the most daunting aspects of developing an embedded system. With μEZ®, the primary features of common multi-tasking operating systems are abstracted, thus easing the transition to an open source or low-cost RTOS. The µEZ® OSAL gives applications access to the following features in an OS-independent fashion:

  • Pre-emptive multitasking
  • Stack overflow detection
  • Unlimited number of tasks
  • Queues
  • Semaphores (binary, counting, mutex)

uEZ Subsystems Drivers

The µEZ® subsystem drivers use the OSAL function to give protected access to the processor peripherals. The subsystem driver API function as are typically protocol layer interfaces (TCP/IP, USB, etc.) designed as high-level access routines, such as open, close, read, write, etc., where possible.

uEZ Hardware Abstraction Layer (HAL)

The HAL functions provide single-threaded unprotected access to the processor peripherals. Customers can use the uEZ HAL routines provided by FDI or they can write their own. The HAL routines provide for RTOS/μEZ® independence and allow portability within a family of processors.

uEZ Project Maker

The µEZ Project Maker allows the user to quickly create an IAR, Rowley CrossWorks, or Keil project. The µEZ Project Maker can be downloaded here.

Frequently Asked Questions

What is μEZ® and how does it help me?
μEZ® is a Rapid Development Platform designed to simplify embedded software development. It should help you get your product to market faster and with a lower development cost than other options. When you get right down to it, what’s more important than saving time and $$$!

The goal of the μEZ® platform is to provide underlying RTOS and processor abstraction, enabling the programmer to focus on the value-added features of their product. μEZ® enhances portability of application code to multiple CPU platforms with high reusability.

Is μEZ® expensive – what does it cost?
μEZ® is an open source, middleware platform so there is no cost to the user. Customers with the necessary engineering resources, a compatible compiler suite, and a little free time can directly integrate μEZ® into their embedded application. For customers with time or resource limitations, FDI offers affordable integration services that are customized to your hardware and software requirements. These FDI integration services are full turnkey, can cost as little as $10K, and may require only 4 weeks of schedule time to complete and test on your hardware.

Where do I get μEZ® and who provides support for the platform?
The µEZ® source code and documentation can be downloaded from https://sourceforge.net/projects/uez. Marketing updates and details on technical support are available at www.teamfdi.com/uez.

Why not use Linux?
Linux is a powerful OS with a much larger code and memory footprint and requiring a processor with a dedicated MMU (Memory Management Unit). μEZ® is designed to work with lower cost processors with smaller memories and, whenever possible, to use only the processor’s internal ROM and RAM. A recent study undertaken by FDI reviewed the cost increases likely for a Linux based system over a μEZ®-based system. The study found a potential hardware cost savings of $25–$40 per unit for the μEZ® system. This savings is significant since it might represent 25–50% of the total embedded hardware cost.

In addition, setting up a full Linux development system can be a source of frustration for many developers. μEZ® uses a single source tree for all its applications and drivers, thus providing a build system compatible with the IDE of choice. Compiling μEZ® is as easy as compiling a single application.

I don’t need all of the features you listed, can μEZ® be trimmed down?
μEZ® was specifically designed and structured to allow developers to pick and choose only the features that are needed for their particular application. Typical code and data memory footprints for μEZ® are 300KB code and 50KB data memory (excluding data memory for LCD or display Frame Buffers).

Can we use another RTOS?
All μEZ® components are made to connect through the μEZ® OSAL (Operating System Abstraction Layer) to the RTOS ensuring compatibility with many different RTOS’s. Currently all μEZ® commercial development by FDI is being focused on the FreeRTOS™ platform since it satisfies the low cost tool requirement because it is “free”. In addition, for medical and intrinsic safety applications FDI partners with Wittenstein to offer a SafeRTOS™ / uEZ platform option. RTOS products from other vendors can also be used with μEZ®.

Which compiler suites do you support?
Currently, μEZ® supports the following three main tool sets:

  • The low cost Rowley CrossWorks compiler
  • The IAR EWARM tool suite
  • The Keil, ARM RealView tool suite

In addition, GNU, HEW – High Performance Embedded Workshop and other compilers can also be used with μEZ®.

What debug tools are available?
Since μEZ® uses the debug tools that are provided in the customers compiler suite, it can be used with any of the tools listed above.

Which processors are supported?
Even though μEZ® is processor independent, all of our initial development has been focused on various members of the ARM Family and Renesas RX families. We currently support the NXP LPC24xx family, the NXP LPC17xx, and the Renesas RX62N family.

If I use μEZ®, do I have to open source my proprietary application code?
No, as long as the code provides functionality that is distinct from that already provided by uEZ.

Do I have to open source my changes to μEZ®?
Yes. When requested, the modified μEZ® source must be provided.

Do I have to document that my product uses μEZ®?
Yes, but a website link to http://www.teamfdi.com is sufficient. The µEZ® trademark or link does not have to appear on your product.

If I create a driver using the μEZ® API, does my driver have to be open source too?
No, drivers created by you are independent modules added to the μEZ® code base per the above exception. However, if you find this source useful to others, we ask you consider making it open source and contribute to the μEZ® code base.

Do I have to offer to provide μEZ® code to users of my application?
Yes.

Can I receive professional support on a commercial basis?
Future Designs, Inc. provides limited basic technical support for uEZ at http://www.teamfdi.com/forum/

For more advanced support, Future Designs, Inc. provides full-service technical support. See http://www.teamfdi.com/support/full-service.php for more details.

Is a warranty provided? Is there legal protection?
No.

Can I use the μEZ® trademark to promote my product?
Yes, but permission from Future Designs, Inc. must be requested by writing to sales@teamfdi.com.
