The EKS-LM3S3748 is an evaluation board designed to give users a working model of the embedded 32-bit microcontroller of the Stellaris family released by Texas Instruments. The onboard resources as well as the minimal cost of the board make it a great option for those who want to find out more about the workings of a microcontroller. In this article, we\'ll discuss the application field and working principle of the EKS-LM3S3748.

Application Field:

The EKS-LM3S3748 board can be applied to a variety of embedded application field, such as industrial control, automotive, medical, consumer products, etc. The applications we can mainly find with the EKS-LM3S3748 board can be labeled as follows:

• Industrial control applications such as robotics
• Sensor and parameter measurement
• Data collection, storage, and transmission
• Power management, etc.

The Stellaris MCU with the EKS-LM3S3748 board contains 5x 12-bit analog to digital converters, up to 8x 10-bit pulse width modulation converters, a serial peripheral interface, as well as a 16-bit timer counter and a 32-bit GPIO port. All of these peripherals are needed to fulfill the tasks in the listed application fields and more. The board is also equipped with a 10/100 Ethernet port, which provides more flexible connection possibilities.

Working Principle:

The EKS-LM3S3748 board is based on the ARM Cortex-M3 microcontroller unit (MCU), which is a high-performance and low-power architecture developed by ARM. The MCU on the board is the Cortex-M3 core, meaning that it implements a 32-bit processor based on the ARM v7-M architecture. There is onboard 128KB flash memory, 16KB static RAM, and 8KB of backup SRAM. The latter is used to store application data which can be retained even when the power is turned off.

The board can be programmed in various methods, such as UART, USB, or Ethernet. Depending on the programming method, the user can use either the board’s on-board JTAG debug or an external JTAG emulators. In order to make development even easier, the board includes the Keil MDK-ARM IDE, a complete development toolkit which consists of the ARM C/C++ compiler, debugger, and programming utilities.

In conclusion, the EKS-LM3S3748 evaluation board is a great choice for those who want to learn more about the ARM Cortex-M3 MCU. With its low-cost, high performance and extensive onboard resources, it can be used for a wide range of embedded applications. It is also very straightforward to use with its intuitive user interface, making it a great tool for those who are just starting out with embedded systems.
