It successfully placed two satellites, Tianyan-16 and Xingchi-1A, into a 500km twilight orbit. This marks the first successful twilight orbit launch by … Read more
Introduction SPI (Serial Peripheral Interface), UART (Universal Asynchronous Receiver/Transmitter), and I2C (Inter-Integrated Circuit) are common serial communication protocols, each with unique characteristics in hardware interfaces and communication methods, suitable for different application scenarios. You can get a general understanding of these three communication protocols from the following diagrams: Next, we will introduce these three communication … Read more
1. Why Is Serial Communication So Popular? When working on microcontroller products, the most commonly used method is serial communication. For any microcontroller peripherals, the priority is to choose those with serial port functionality, such as Bluetooth modules, WIFI modules, 4G modules, electric meters, and displays. Why Is Serial Communication So Popular? Because it’s simple! … Read more
Click the blue text above to follow us The main reason for adding a 22Ω or 33Ω resistor in series when a microcontroller uses SPI to connect to a sensor or controller is to suppress reflections and ringing. 1 Principle of Reflection and Source Matching In high-speed digital signal transmission, when the signal driver (such … Read more
This article introduces the SPI mechanism in Spring. abstract.png Basic Practice Spring SPI draws on the design philosophy of Java SPI. It implements the SPI mechanism through the spring.factories method, providing extensibility to the framework without modifying its source code. Specifically, we first define an SPI interface. package com.aaron.application.SpringSpi.BasicSpiDemo; public interface Greet { void hello(); … Read more
1. Completed IIC and SPI communication using software simulation; 2. Next, prepare to use DMA to transfer SPI data and calculate the angle time for reading once.

Since the launch of the three-year action plan for state-owned enterprise reform, State Power Investment Corporation (SPIC) has earnestly implemented the decisions and deployments of the Party Central Committee and the State Council, and has solidly promoted the implementation of various reform tasks in accordance with the requirements of the State Council’s Leading Group for … Read more
For more experience sharing, follow RF Engineer When a microcontroller or FPGA sends SPI control signals to a phase-locked loop chip, it often requires a series connection of a 22 ohm or 33 ohm resistor. What is the reason for this? Impedance discontinuities can cause electromagnetic wave reflections, which in turn lead to signal distortion. … Read more
