Overview:The I2C communication interface is the most commonly used MCU peripheral in our daily applications. Initially, before the MCU had hardware I2C, I2C communication was achieved by simulating the I2C timing through GPIO ports. Later, with the introduction of hardware I2C peripheral interfaces in MCUs, the use of hardware I2C became commonplace. More importantly, it … Read more
Bus applications are very widespread in the field of computers. (1) The method of transmitting information via the system bus can be divided into the following three types: 1. Data Bus 2. Address Bus 3. Control Bus (2) According to the usage range of the bus, it can be further divided into many types: such … Read more

I2C Introduction 1.1 I2C History I2C: Inter-Integrated Circuit, an integrated circuit bus. I2C is a simple, bidirectional two-wire synchronous serial bus designed by Philips in 1982 … Read more
Click the blue text above to follow us 1. What is I2C? I2C, short for Inter Integrated Circuit, is a two-wire serial bus developed by Philips for communication between SOCs and peripherals. It requires only two wires for communication, operating in a master-slave mode where the master can read and write data, while the slave … Read more
Satellite communication typically occurs in one of ten frequency bands. The specific frequencies available within each band depend on applicable licensing regulations. While certain portions of the bands are allocated globally for satellite use, others may be exempt from licensing and can be used in specific circumstances. The International Telecommunication Union (ITU) is responsible for … Read more

Programming is a term that tells computers how to work. Through programming, we can easily manipulate any technology. Just like everyone has their own language or specific dialect in certain regions, computers or advanced technologies also have specific languages, and its name is “programming.” Those who engage in programming are called programmers. However, merely learning … Read more
