I need to do manipulation with my incoming data fr serial port n need to have a look-up table for this purpose, starting from 0.0dB and 30H data. For every increment of hex value, the level increases by 0.5dB.

My data has been converted to hex format, then i need to convert it to dB value based on the look-up table. How can this be done?


This is what i mean:
LEVEL DATA
0.0dB 30H "0"
0.5dB 31H "1"
1.0dB 32H "2"
.
.
.
15.0dB 4FH
.
.
49.5dB 93H
50.0dB 94H
