MIPI is a serial interface, and MIPI-DSI is the technology used for displays. LCD displays with MIPI interfaces serve as display outputs, enabling graphical user interfaces that allow ordinary users to skillfully operate computers and other devices. Therefore, MIPI is an important interface for human-computer interaction. In addition to the previously mentioned camera recording driver … Read more
With the development of Internet of Things (IoT) technology, more and more sensors are being applied to various devices. Sensors produced by Sensirion are known for their high precision and reliability, among which I2C communication sensors are particularly common. To facilitate developers in using these sensors, the sensirion-i2c-sdp library has emerged. This article will detail … Read more
Click the top to follow us! 01 Introduction Common NFC tags generally do not require power; they only need to be brought close to a mobile phone with NFC functionality. The coil antenna on the phone induces mutual inductance with the coil antenna on the tag, causing a changing current of 13.56M to flow through … Read more
I2C is a two-wire serial communication bus, consisting of an SCL signal and an SDA signal. SCL is the clock signal sent from the master device, while SDA is the data signal, which is bidirectional, allowing devices to send and receive data through the SDA signal. When designing the I2C signal circuit, we add a … Read more
Many people do not know how to write programs by looking at timing diagrams. Below, we will analyze a non-standard I2C device and teach everyone how to write an efficient IO simulation of I2C timing. Observing the timing diagram, it includes the I2C start signal, I2C stop signal, I2C acknowledgment, non-acknowledgment, response acknowledgment, as well … Read more
I2C Protocol Application: Sensor Interface and Data Reading I2C Protocol Application: Sensor Interface and Data Reading Hello everyone, I am Daodao. Today, let’s talk about the I2C protocol, which many sensors use to communicate with microcontrollers. Although it only uses two wires, it can connect multiple devices, making it a master of saving wires. However, … Read more
I2C is a common serial communication interface, which is available on most processors. The I2C interface is an open-drain structure, so pull-up resistors are needed in the design to drive the high level. As shown below: Rp is the pull-up resistor, and the dashed box contains the internal I2C controller structure of the chip (for … Read more
To start, why do I write IIC instead of I2C in my article? Because they are the same thing, and it’s easier for me to write as IIC Today, we will look at how to use IIC in the STC library functions. There are three sets of pins available for us to choose from, and … Read more
