This article discusses Linux device drivers. In Linux, I/O devices can be divided into two categories: block devices and character devices. These two types of devices do not have any hardware differences; they are mainly classified based on different functionalities, and their main difference lies in whether they can randomly access and manipulate data on … Read more
Author | Acuity 1. Introduction The I2C bus is a simple, “bidirectional two-wire synchronous serial bus” developed by PHILIPS. The use of I2C is not unfamiliar; C51, ARM, MSP430, etc., generally integrate hardware I2C, or for those that do not integrate I2C, it is possible to simulate an I2C bus using ordinary IO ports based … Read more
