It took almost a week to learn drivers. During this period, I was busy learning Linux application programming, search driver, and kernel-related books for further study. In the previously friendly driver routines, the knowledge involved is very limited. It is imperative to study more driver source code and learn more about dr
The 16c2550 serial port chip can be used to expand two serial ports. Its operation method and register usage are exactly the same as 8250, so we can use the classic 8250 driver in Linux to drive st16c2550. 8250 the driver remains unchanged. You need to add the 16c2550 initia

How to install the driver in Win8.1 can solve problems such as virtual serial port installation and VMware bridge driver installation ., Win8.1vmwareA virtual machine is installed in win8.1, but there is no virtual network card vmnet0 vmnet1 vmnet8?The network cannot be changed to the bridging status: Is there no host
sending and receiving dual-end processors with Low Speed. Therefore, hardware Throttling is required. The other pins are related to the modem. The data set ready of the DSR data device is used to indicate that the modem is in usable state. Data Terminal ready indicates that the data terminal can be used. These two signals are used to check whether the modem is connected. This pin is set by the modem when the Dell pin has a phone dial. The DCD signal is set when the modem receives the digital ca
Windows CE, as a typical embedded operating system, is typical for other embedded systems such as PSOs + and nucleus us by porting Bluetooth applications to widows ce.
