ps2 key board data conversion

raman00084 · Jul 9, 2014

i have a ps2 key board program that decodes the key press value into ascii. example the return value of the ps2 key board is
ps2_keyvalue= 64
how to convert the ps2_keyvalue to my assigned value for example

ps2_keyvalue = 64 for the 64 i am assigning another value example 10
like this i will be assigning different values for different ascii codes
can i use array for this?

please send some c code for doing the above job i am a beginner in c

Assign an array of char, with the all values you want, and read it with the keyvalue as index. This will work as a lookup table.

have a look at
https://electronic-engineering.ch/microchip/projects/keyboard/v1xx/keyboard_v1xx.html

as Gorgon says use a lookup table, for example

Code:

// alphabetic codes
const ScanCode alphaCodes[]={
	{0x15,'q','Q'},
	{0x1D,'w','W'},
	{0x24,'e','E'},
	{0x2D,'r','R'},

code 0x15 is read which in the Keyboard Scan Codes lookup table is q or Q (depending on the shift key)
