1. Scan Code Mode:
This is the standard code of PC keyboard designation, when you press a key, there are two kind
of code sending. One is "make code", and another is "Break code" when key-press-down, it
makes a key data: "Make Code", when key-press-up, it makes a key data called: " Break Code",
this mode is useful for normal application design.
Note:
In scan code mode, if you design a key "A", the software will get data "A" or "a" that
depends on the "Caps lock" status.
2. ALT mode code:
Sometimes, user cannot use "Scan Code" for special application design, so, there's a "ALT
mode" code for user easier to design theirs application. The ALT-mode is for sending ASCII
code, and through PC keyboard. The method is use "ALT" key and the
numbers of PC keypad.
For example, Code number "A" in ASCII table is "65". So, you may keep press "ALT" function
key and then press number "6", and number "5", after that, release "ALT" key, the "A" will
appears on the screen.
Note:
In ALT mode, if you design a key "A", the software will only get data "A".
