Communication protocols in embedded microcontrollers play a crucial role in interfacing and networking with external devices. The most commonly utilized protocols include UART, I2C, SPI, CAN, LIN, as well as analog and digital communication interfaces. However, based on a comprehensive survey, it has been observed that these protocols are not universally integrated into all widely used 8-bit microcontrollers designed for embedded applications. Consequently, during the development of embedded systems, there is often a need for protocol conversion to ensure seamless communication and system functionality. To address this requirement, hardware and software solutions have been developed using the ATMEGA 328 microcontroller. This system facilitates data exchange by receiving input from one communication protocol and converting it into another. Additionally, a keypad interface and a 2×16 LCD module are integrated to enable users to select the desired protocol conversion. The necessary peripheral devices are interfaced under the specified protocols, and the accuracy of the protocol conversion process has been validated through practical implementation. This conversion system serves as a valuable tool for embedded application development, enabling seamless interoperability between various communication protocols and enhancing system integration efficiency.
