UART (Universal Asynchronous Receiver/Transmitter) is a universal asynchronous receiver and transmitter commonly used for serial communication. In Linux systems, the UART driver is implemented to control and manage UART devices. This article will introduce in detail how to implement UART driver in Linux system and provide corresponding source code examples.
- Registering a UART device
In a Linux system, you first need to register the UART device so that the system can recognize and manage it. The following is an example device registration function:
#include <linux/module.h>
#include <linux/platform_device.h>
static struct platform_device uart_device = {
