To solve this issue most of the microcontrollers and boards come with A/D converting channels. Most of the sensors need to measure the value in the analog signal but it becomes unreadable by most of the devices. MSP432 Analog to Digital Converter ChannelsĮvery electronics device works with digital data but in real life, it’s the opposite. As a default, the I2C uses I2C(1) but to use I2C(0) the programming should be used. Every microcontroller comes with the I2C method and MSP432 also has two I2C communication ports, one is I2C(0) and the second is I2C(1). Clock pins keep the data sync between two devices according to the clock pulse. In I2C only two wires are used, one for clock and second for data. Most of the slow operating devices use I2C communication. The I2C protocol is also a serial protocol but it is known as the two-wire communication method. In most of the boards and microcontrollers, it remains one as predefined for only one module but it can be designed by converting any I/O pin through programming. CS means chip select, which is used in the case of multiple devices. SCK is for clock pulse to send and receive data according to the clock signal and the last pin is CS. The second pin is MISO knows as Master in slave out, which is used to send the data from external modules to the board. It is used to send the data from the board to the external module. SPI communication is also known as three-wire communication. It will depend on the developer in which pins are chosen. In MSP432 there are three ways for UART communication.Īll these are connected and only one communication can use for UART communication. UART communication uses only two wires for communication and the rest of the communications depend on the programming. Serial UART communication is one of the most used serial communication nowadays because of its efficiency. All these communications protocols and their pins are given below: Serial UART Communication Pins The board offers some modern serial communication pins, which can communicate with multiple devices and sensors.

The low pulse will be able to change the state of the digital pin for input. All I/O pins come with an internal pull-up resistor. Sometimes a smart programmer can also build the unbuilt in function by using programming through I/O. these functions are the most used functions by external sensors and peripherals.
