CDBWM8804-1 is a evaluation and demonstration board and kit based on LIN bus technology featuring both masters and slaves capability for prototyping applications. Its main features are: embedded 8-bit microcontroller with LIN2.0/2.1 communication interface; 1 Kbyte RAM and 64 Kbytes Flash; USB interface and 16 port I/Os for simple operation.

This board is suitable for real-time, low-cost applications requiring quick and easy development of LIN bus applications. The board is easy to use and can easily be set up for prototyping applications in fields such as automotive industry, medical equipment, industrial control, and home automation.

LIN is a bus system using a single-wire connection for transmitting data between modules (or microcontrollers) located in a car. The CDBWM8804-1 is aimed atLIN applications featuring multiple controllers on the same bus. It supports LIN2.0 and LIN2.1, which are both asynchronous serial communication protocols. The microcontroller on the board is used in order to communicate with other LIN modules over the bus and to execute commands.

The primary purpose of the board is to facilitate a quick and easy development ofLIN bus applications. For this purpose, the board includes connectors for power supply, USB connection with PC, RS-232 connection and I/O ports. CDBWM8804-1 also includes a demo application that allows the user to quickly verify the board operation.

The working principle of the board is quite simple. The board includes a master controller (MCU) and aslave controller (SCU). The MCU sends a request for the LIN bus data to the SCU andthe SCU responds with the requested data. The MCU then processes the data accordingly.This process continues until the MCU and the SCU reach a state of agreement on thedata exchange. Once the agreement has been reached, the data transfer is ended and the process can be repeated.

At its core, the CDBWM8804-1 helps accelerate the development ofLIN applications. On the hardware side, it provides connectors for power, USB and RS-232 connection, as well as I/O ports. At the software side, the board includes a demo application that allows the user to quickly verify the board operation.

For automotive industry, medical equipment, industrial control, and home automation, this board is a great wayto quickly and easily develop LIN bus applications. Its low cost and simple setup make it a great tool for prototyping applications.
