Evaluation and Demonstration Boards and Kits, such as the EVAL-L9779WD-SPI, have become an integral part of the development process for anyone designing a project or considering using a specific technology, component, or system. They are designed to help engineers gain a better understanding of the design principles and working characteristics of the components they are using before they build their own versions. The EVAL-L9779WD-SPI in particular is an SPI-Bus/UART to I2C-Bus Interface Demo Board from STMicroelectronics, allowing embedded system designers to quickly evaluate and develop their designs.

The EVAL-L9779WD-SPI is an evaluation board for the L9779WD, an SPI-Bus/UART to I2C-Bus interface gateway. This board provides a demonstration of how to use the L9779WD and its capabilities in a real-world application. The board includes connectors for the L9779WD, an SPI-Bus Ethernet jack, a dual-row DIP switch, pushbuttons, LEDs, and a 4-strand ribbon cable. The 4-strand ribbon cable provides connection to the I2C-Bus peripherals and I2C-Bus masters. The board is designed to allow easy access to the SPI- bus, UART, and I2C-Bus lines.

The pins of the EVAL-L9779WD-SPI board, along with the 4-strand ribbon cable, allow for the connection of both SPI masters and I2C masters. The power supply for the board is provided through a male power jack and a socketed voltage regulator. The board includes two tactile buttons, one of which resets the connection to the I2C-Bus. The other button can be used to select a different I2C-Bus master to use for communication.

The board features a 3-level LED brightness control which can be used to adjust the brightness of the display. There are also two LEDs, one green and one red, which are used as activity indicators for the I2C-Bus signal lines. The board also provides access to the L9779WD through a micro-USB port and includes an on-board EEPROM, allowing for configuration and diagnostic purposes.

The EVAL-L9779WD-SPI board provides engineers with a complete evaluation platform for the L9779WD SPI- Bus/UART to I2C-Bus interface gateway. The design and included components of the board enable engineers to quickly and easily evaluate and develop their own designs using the L9779WD. From embedded system development and I2C-Bus probes to data acquisition and sensory I/O, the EVAL-L9779WD-SPI board allows for rapid development and prototyping of applications and systems.

The EVAL-L9779WD-SPI board provides a comprehensive evaluation and development platform for embedded system designers. It offers an easy way to evaluate the functionality and capabilities of the L9779WD before designing their own version. The board features a host of connectors and components which makes the evaluation process for the L9779WD simple and straightforward. The EVAL-L9779WD-SPI board is an ideal way for engineers to gain a better understanding of the design principles and working characteristics of the L9779WD before investing time and resources into building their own versions.
