Methods for Reading Data from the ICM-40609-D Sensor Using STM32 Microcontroller
The ICM-40609-D is a high-performance six-axis MEMS sensor chip that integrates a 3-axis accelerometer and a 3-axis gyroscope, specifically designed for the drone market. It can replace previous models such as the ICM-42688, ICM-20602, and MPU6500. This chip is manufactured using advanced MEMS technology, featuring a compact size, low power consumption, and high accuracy. Its … Read more
Native Android Experience on K40 – LineageOS
When feeling bored, I often think about tinkering with the electronic products around me, wondering if there could be a better or different experience.For most people, smartphones are essential daily tools, and how comfortable they are to use is quite important. My old phone, the K40, has been in use for four years. Since I … Read more
Arduino Orientation Sensing: LED Lights Changing with Angle
Introduction A few years ago, I heard about a creative door lock project: the user holds a sensing device and waves it in a specific manner. Once the device recognizes the action, it unlocks the door. This action becomes a form of key. I broke down this project into hardware and software components. The hardware … Read more
How Can Mobile Phones Participate in Earthquake Early Warning?
As one of the most destructive natural disasters, the construction of an earthquake early warning system has always been a significant topic in the scientific community. In recent years, with breakthroughs in smartphone technology, global research teams have discovered a disruptive solution: utilizing the built-in sensors of billions of smartphones to construct an earthquake sensing … Read more
Working Principle of Accelerometers
What is a Sensor? A sensor is essentially a device or apparatus that can “convert physical quantities.” To obtain information for detection and control, it is necessary to convert the state, properties, and physical changes of an object into electrical quantities, using various physical laws for this conversion. Representative physical quantities that sensors detect and … Read more
Raspberry Pi | Angular Velocity and Acceleration Sensors
Click the above“Mechanical and Electronic Engineering Technology” to follow us Angular velocity sensors and acceleration sensors are common inertial sensors, often used to measure the rotation and linear motion of objects. The angular velocity sensor (Gyroscope) is used to measure the rotational speed or angular velocity of an object around three axes (X, Y, Z). … Read more
Comprehensive Overview of ROM, RAM, and FLASH
Source: Technology Makes Dreams Greater Compiled by: Li Xiaoyao A few days ago, I happened to discuss some knowledge about ROM, RAM, and FLASH with my colleagues. Suddenly, when we talked about these English terms, we realized our understanding was quite superficial. Among us, the meanings of some MCU terms were also unclear, so tonight … Read more
Gains and Reflections on Adapting Android System for Xiaomi Mi Pad 2
I have a wish: to run a 64-bit Android 9.0 on the Xiaomi Mi Pad 2. The compatibility of 64-bit Android 9.0’s houdini is excellent. I once tried to implant houdini 9 into Android_x86-9.0 r2 and then installed it on the Xiaomi Mi Pad 2. I found that the apps ran very stably, and the … Read more
The Role of ROM, RAM, and Flash in Microcontrollers
Generally, ROM is used to store firmware, while RAM is used to hold data. Since FLASH ROM has faster read and write speeds and is easier to erase compared to ordinary ROM, it is typically used to store user programs and data that need to be permanently saved. For example, the core of a household … Read more
