![]() The transmission mode is Half-duplex ie the transmission between devices is alternated.Īs shown by the previous image, we can use this communication to put in communication different peripherals as Analog-Digital Converters (ADCs), Digital-Analog Converters (DACs), EEPROM memories, sensors, LCD screen, RF module, Real-Time Clock, etc. In any case, there are many guides to size them and we refer their reading to the more attentive reader. The value of these resistors depends on the bus length ( ie the bus capacitance) and the transmission speed. SDA and SCL lines need to be pulled up with resistors. SCL (Serial Clock) is the line dedicated to the clock to synchronize the data flow.SDA (Serial Data) is the line where master and slave send or receive the information (sequence of bit).up to 128 devices can be connected to each other.is more tolerant of interference and transmission errors.it requires fewer wires and pins available on the integrated circuit with a consequent reduction in costs and space on the board.Although the communication modules are more complex than the parallel transmission, the serial mode is one of the most widespread especially in communications between chips that must communicate with each other over great distances, because: Serial transmission is a mode of communication between digital devices in which bits are sent one at a time and sequentially to the receiver in the same order in which they were transmitted by the sender. The bus was conceived and developed by Philips (now NXP) It was designed to overcome the difficulties inherent in the use of parallel buses for communication between a control unit and various peripherals. Like any serial protocol, one of its advantages is that of using only two lines that transmit or receive a sequence of bits, the limit is the communication speed which has been improved over the years. ![]() ![]() I☬ (Inter-Integrated Circuit) is a two-wire serial communication system used between integrated circuits. So, let's first have a look at what is I2C Communication: What is I2C Communication? ![]() Today, we will study another way of communication(i.e. In the previous lecture, we have discussed STM32 Serial communication both in Interrupt Mode and polling Mode. I am going to use the Nucleo board for today's lecture. In today's lecture, we will have a look at the I2C Communication with STM32 Microcontroller board. Hello friends, I hope you all are doing great. ![]()
