High Quality Content by WIKIPEDIA articles! Digital One Line Link (DOLLx8) is a technology architecture that consists of data communications protocol, synchronous serial data bus and a communication system that is designed to make other interdisciplinary development projects within embedded systems and electronics much easier and more accessible to the users. DOLLx8 use ASCII characters in its data protocol, differential signaling in the bus system, where the communication consists of an active long-distance technology based on system logic where handling of the communication is done automatically by the microcontroller and its internal embedded Real-time operating system (RTOS) and software.
