The Q9 input method (Chinese: 九方輸入法), invented by Qcode Information Technology Ltd. of Hong Kong, is an input method that uses only the number keys on a numeric keypad to input Chinese characters into a digital device.
In computing, a keyboard controller is a device that interfaces a keyboard to a computer. Its main function is to inform the computer when a key is pressed or released. When data from the keyboard arrives, the controller raises an interrupt (a keyboard interrupt) to allow the CPU to handle the input.
The keyboard layout for the Dayi input method contains keys for many of the Kangxi radicals in its entirety. This means that a single keystroke accounts for the left half or right half of many Chinese characters. For instance, "車" in "輸" (6AJN) is represented by "6". This allows for characters to be represented by 4 keys or less. [1]
The SIGTSTP signal is sent to a process by its controlling terminal to request it to stop (terminal stop). It is commonly initiated by the user pressing Ctrl + Z . Unlike SIGSTOP, the process can register a signal handler for, or ignore, the signal.
Cangjie is the first Chinese input method to use the QWERTY keyboard. Chu saw that the QWERTY keyboard had become an international standard, and therefore believed that Chinese-language input had to be based on it. [3] Other, earlier methods use large keyboards with 40 to 2400 keys, except the Four-Corner Method, which uses only number keys.
A general-purpose input/output (GPIO) is an uncommitted digital signal pin on an integrated circuit or electronic circuit (e.g. MCUs/MPUs) board which may be used as an input or output, or both, and is controllable by software.
Simplified Cangjie, known as Quick (Chinese: 速成或簡易) is a stroke based [1] keyboard input method based on the Cangjie IME (Chinese: 倉頡輸入法) but simplified with select lists. Unlike full Cangjie, the user enters only the first and last keystrokes used in the Cangjie system, and then chooses the desired character from a list of ...
