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
Soy protein isolate (SPI) is a major source of high-quality protein, low in cost, and has high nutritional value. The use of polyphenols to improve the functional properties of proteins has become a research hotspot. Blueberry anthocyanins (BANs) are a type of polyphenolic substance with rich biological activity. The interaction between BANs and SPI can … 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
Soy Protein Isolate (SPI) has attracted much attention due to its rich nutritional content and excellent functional properties. SPI emulsification refers to the process of disrupting the water-oil balance under the action of shear or breaking forces, uniformly dispersing oil droplets as extremely small liquid droplets in immiscible water, forming a homogeneous and stable water-oil … Read more
Soy Protein Isolate (SPI) is an important plant protein that is widely used in the food industry, agriculture, and biotechnology due to its high nutritional value, low production cost, excellent biocompatibility, and processing characteristics. Numerous studies have shown that the functional properties of SPI can be improved through non-covalent or covalent binding with small molecular … 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
