Recently, I saw some netizens discussing whether ‘CAN is more difficult than UART’ in a technical group. Some netizens said CAN is very simple, while others said CAN is very difficult. In fact, whether it is difficult or not mainly depends on your perspective. Some netizens may have a good foundation and have studied CAN, … Read more
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
