It can transmit data at long distances at the cost of transmission speed. The typical data speed of the 1-Wire interface is about 16.3 kbit/s, and the maximum length is approx. 300m. Name 1-Wire comes from the feature that the data line can directly power elements connected to the bus.

Only two voltages are delivered to the devic… text/html 2024-05-27T10:16:58+00:00 Anonymous (anonymous@undisclosed.example.com) https://home.roboticlab.eu/en/iot-open/embeddedcommunicationprotocols2/spi?rev=1716805018&do=diff SPI [ General audience classification icon ][ General audience classification icon ] One of the most popular interfaces to connect different external devices is SPI (Serial Peripheral Interface). It is a synchronous serial interface and protocol that can transmit data with speeds up to 20 Mbps. SPI is used to communicate microcontrollers with one or more peripheral devices over short distances – usually internally in the device. High transmission speed enables SPI to be suitable even for sendi… text/html 2024-05-27T11:11:37+00:00 Anonymous (anonymous@undisclosed.example.com) https://home.roboticlab.eu/en/iot-open/embeddedcommunicationprotocols2/twi?rev=1716808297&do=diff TWI (I2C) [ General audience classification icon ][ General audience classification icon ] TWI (Two Wire Interface) is one of embedded systems' most popular communication links and protocols. Philips has designed it as an I2C (Inter-Integrated Circuit) for audio-video appliances controlled by the microprocessor. Many chips can be connected to the processor with this interface, including: text/html 2024-05-27T11:26:06+00:00 Anonymous (anonymous@undisclosed.example.com) https://home.roboticlab.eu/en/iot-open/embeddedcommunicationprotocols2/uart?rev=1716809166&do=diff UART [ General audience classification icon ][ General audience classification icon ] UART name is an abbreviation of Universal Asynchronous Receiver Transmitter. It is one of the most often used communication methods, traditionally named serial interface or serial port. In contrast to previously presented interfaces, UART uses direct point-to-point communication. UART is the communication unit implemented in microcontrollers rather than the communication protocol. It sends the series of bits…
