Communication Methods Between Devices Generally, the communication methods between devices can be divided into two types: parallel communication and serial communication. The differences between parallel and serial communication are shown in the table below. Classification of Serial Communication 1. According to the data transmission direction, it can be divided into: Simplex: Data transmission only supports … Read more
In embedded systems, on-board communication interfaces refer to the communication paths or buses used to connect various integrated circuits with other peripheral devices. The following content summarizes commonly used on-board communication interfaces: including I2C, SPI, UART, and 1-Wire: I2C Bus The I2C bus is a <span> synchronous, bidirectional, half-duplex two-wire serial interface bus</span>. Here, half-duplex … Read more
Understanding OBG in Microcontrollers: The STM32 microcontroller’s core (Cortex-M3) contains a hardware debugging module that supports various complex debugging operations. The hardware debugging module allows the core to halt when fetching addresses or accessing data—this is the assurance we have for online simulation during microcontroller development and debugging.When the core is halted, both its internal … Read more

UART is an asynchronous full-duplex serial communication protocol consisting of two data lines, Tx and Rx. Since there is no reference clock signal, both parties in communication must agree on serial baud rate, data bit width, parity bit, stop bit, and other configuration parameters to communicate at the same rate. Asynchronous communication transmits one character … Read more

UART communication is an asynchronous communication method, where both the sender and receiver must communicate at an agreed baud rate. When there is an error in the baud rate, it can lead to communication errors. So, what factors can lead to errors in the baud rate? 1. Frequency Division Error Firstly, the baud rate is … Read more
