To install a driver under Windows, we need to pack all the software you need-called a driver package. The driver package includes the general installation tools provided by the system for all device classes, and includes device-specific components provided by the device vendor. Let's take a look at what components are specifically needed in the

The MQ-2 Smoke gas sensor module is driven on the X210v3 Development Board.It is now necessary to drive a MQ-2 smoke gas sensor module. After detecting smoke exceeding a certain standard, it will return a different level, similar to the key driver.But when writing the driver, you need to use the Gph2_3 number PIN. However, the Ioremap address is then configured in the kernel, and it is not possible to control the GPIO or enter the interrupt.It was lat

Access to the character device is performed through the device name in the file system. Those device names are simply nodes that are called file system trees, and they are typically located in the/dev directory. Device files for character device drivers can be identified by ' C ' in the first column of the ls-l command output. Block devices are also located in/dev, identified by the character ' B 'CRW-RW----1 root root 253, 0 2013-09-11 20:33 Usbmon0CRW-RW----1 root root 253, 1 2013-09-11 20:33
