In many circuits, small-value resistors are connected in series. Don’t underestimate them; they actually play a significant role. 1. SPI Signal Lines For SPI signals, the series resistor is generally around tens of ohms and has the following functions: 1) Impedance Matching. Since the impedance of the signal source is very low, and there is … Read more
Source: ICisC Nanjing Integrated Circuit Industry Service Center 1. Concept: SPI: Serial Peripheral Interface The SPI flash is a flash storage device that operates through a serial interface. Flash memory is categorized into two types based on its internal storage structure: NOR flash and NAND flash. Here, SPI flash belongs to NOR flash! SPI flash … Read more
Java 6 introduced a feature for discovering and loading implementations that match a given interface: the Service Provider Interface (SPI). SPI is a mechanism provided by Java to discover and load implementations that match a given interface. It is mainly used to extend existing system applications, among other things. There are many applications in the … Read more

In the field of electronic engineering, IIC and SPI are two common wireless communication protocols used in various communication devices, with a wide range of application scenarios. However, many beginners in electronics are unclear about the differences between these two protocols, so this article will elaborate on both protocols. 1. IIC IIC, short for Internet … Read more
UART, SPI, I2C and other serial communications are very common methods in embedded development. The underlying communication principles are not difficult, but many beginners struggle to learn them. Today, I will share some common underlying data transmission principles of communication. 1UART Serial Port UART: Universal Asynchronous Receiver/Transmitter. The UART serial port is the most common … Read more
Introduction SPI (Serial Peripheral Interface) is a synchronous serial interface technology introduced by Motorola. The SPI bus is physically implemented through a module called Synchronous Serial Port (MCU) on the microcontroller (PICmicro) connected to peripheral devices, allowing the MCU to communicate with various peripheral devices at high speed in a full-duplex synchronous manner. SPI The … Read more
1. What is SPI? SPI stands for Serial Peripheral Interface, a synchronous serial interface technology introduced by Motorola. It is a <span>high-speed</span>, <span>full-duplex</span>, and <span>synchronous</span> communication bus. 2. Advantages of SPI Supports full-duplex communication, simple data transmission rate. 3. Disadvantages There is no specified flow control and no acknowledgment mechanism to confirm whether data has … Read more
（长按 识别二维码 搜索更多麻醉学知识点） 【Definition】 The Surgical Pleth Index (SPI) is a monitoring tool that measures the photoplethysmographic signal from the fingertip to monitor the nociception-anti-nociception balance during general anesthesia. 【Principle】 Stress stimuli activate the peripheral sympathetic nervous system, inducing distal vascular contraction. By measuring the absorption of red light from the fingertip, the photoplethysmographic pulse … Read more
