1 I2C Bus The programming related to I2C mainly involves two situations: ARM chips with dedicated controllers and microcontroller chips without controllers. For ARM chips with controllers, operations are performed based on the data manual by setting the corresponding registers (control registers, status registers, etc.); however, for microcontroller chips without controllers, I2C protocol needs to … Read more
When connecting a microcontroller to sensors, displays, or other modules, have you ever considered how the two devices communicate? What exactly are they saying? How can they understand each other? Communication between electronic devices is like communication between humans; both parties need to speak the same language. In electronics, these languages are called communication protocols. … Read more
