INCOMING ASCII CODE TO USB PC KEYBOARD KEY TRANSLATION

Community General Discussion

HI to all the forum members,

I designed a board with 8keys, as we all know that with the help of this 8keys we can produce 256 combinations.

i took few combinations and written code to generate ASCII values with respected those combinations which matches our standard PS-2 keyboard ASCII values.

FOR EXAMPLE
combination ASCII(HEX) KEYBOARD FUNCTION
00101011 41 A
00101100 42 B
00101101 43 C
. . .
. . .
. . .
10000000 09 TAB
10000001 0D ENTER
10000010 E2 WINDOWS
. . .
. . .
. . .

here i attached a video of it where i printed alphabets and numbers in hyper terminal window.

but now i need to control my computer with the combination of this 8key board instead of standard ps-2 key board.

i connected the board to the computer through USB interface not RS232.

now i need to translate those ASCII CODE TO USB PC KEYBOARD functionality.

QUESTIONS?

Should i need any Hardware in between the board i designed and the PC.

OR should i need any software to be loaded on the PC so that it would convert the incoming ASCII value in to key board functionality so that i can control my PC (i.e., like when we connect a standard PS-2 OR USB based keyboards to our PC it asks for drivers).

AND with what baud rate should i transmit those ASCII values to the computer , for the above example i used 9600 baud rate.

Many modern Arduinos can be reprogrammed to look like a keyboard. Once you do this, though, programming gets trickier. Here's someone who looks like he's done it:
