Preface: If read/write in the driver method is unavailable, the user may call read. When the output buffer is full, the device is not ready to accept the data, in this case, the driver can block the process and put it in sleep state until the conditions are met. 1. Sleep When a process is sleep, it is marked as a special State and moved from the running queue of the scheduler until it is modified in some c

adcdat0 register) is read. Otherwise, set the enable_start bit to start A/D.(4) When the conversion ends, read the adcdat0 register to obtain the value. If you use the query method, you can choose not to read the ecflg bit of the adccon register to determine whether the conversion is complete. Otherwise, you can use int_adc to interrupt the conversion. If int_adc is interrupted, the conversion is complete. ADC Driver code: http://www.cnblogs.com/hoys

How does Win10 set to stop automatic driver installation and win10 to stop the driver? Since VISTA, windows has started to have the function of automatically updating the driver of the device. Of course, this can be disabled/enabled. The following section describes how to disable automatic installation of the driver i

I. Linux USB driver levels 1. devices, configurations, interfaces, and endpointsThe logical organization of a USB device consists of four layers: device, configuration, interface, and endpoint. A device usually has one or more configurations: Each USB device provides different levels of configuration information, which can contain one or more configurations, different Configurations enable devices to exhibit different combinations of functions (

Access control is sometimes critical for the reliability of a device node. This part of content is only modified on the open and release methods, and some check mechanisms are added. Exclusive Device The most rigid access control method is to allow a device to be opened (exclusive) by a single process at a time, which is the simplest access control for a device driver. The implementation is very simple. For specific code, see the experiment source co
