Introduction In low-power applications, it is sometimes necessary to put the MCU into STOP mode to save power. In some chip architectures, to achieve this, the serial port pins are often configured as general I/O pins with external interrupt mode before entering low-power mode. While this can achieve the desired effect, it inevitably leads to … Read more

1. UART (Universal Asynchronous Receiver/Transmitter) The host and slave must connect at least three wires: RX, TX, and GND. TX is used for sending data, while RX is for receiving data (the transmission and reception are not on the same line, hence it is full-duplex). Basic Characteristics: Asynchronous Communication: No shared clock signal, relies on … Read more
The SPI protocol is a commonly used high-speed, full-duplex, synchronous serial communication protocol, widely used for data exchange with sensors (such as temperature sensors, pressure sensors, etc.), data storage and retrieval from storage devices (such as EEPROM, FLASH memory), control of display modules (such as LCD screens, OLED screens, etc.), communication with wireless communication modules … Read more
SPI (Serial Peripheral Interface) is a synchronous serial communication protocol widely used in embedded systems and peripheral communication. SPI follows a one-master, multiple-slave communication method. Based on its operating modes and extended functionalities, SPI can be categorized into the following types based on hardware connection methods: 1. Standard SPI, commonly referred to as SPI, it … Read more
Ahem… another sleepless night tortured by SD cards! I remember a young engineer asking me last week, “Why does his data keep disappearing after writing?” This reminded me of my own struggles back in the day. The SD card, though seemingly insignificant, often gives engineers a headache… What exactly is an SD card? Simply put, … Read more
In modern electronics manufacturing, Surface Mount Technology (SMT) plays a crucial role. The SPI (Solder Paste Inspection) at the second SMT station is an important inspection process in the SMT production line, which is essential for ensuring product quality, improving production efficiency, and reducing production costs. One day, on the SMT production line, the SPI … Read more
Introduction During the project development process, it was found that the actual baud rate configured for the MCAL SPI did not match the clock frequency captured by the logic analyzer. The actual frequency was only half of the configured value. This article documents the troubleshooting process for this issue. MCAL Configuration Check The baud rate … Read more
Formatting | Last BugThe main content shared today is derived from ADI’s SPI knowledge study. SPI is one of the most commonly used communication methods in embedded development. However, most embedded software engineers often focus more on upper-layer software development and tend to overlook some underlying signal formats. When communication issues arise, it can be … Read more
