CONTRAST | P | 50h |
BRIGHTNESS | Q | 51h |
TINT | S | 53h |
COLOR | T | 54h |
How to set the grade
The data code of CONTRAST and BRIGHTNESS is structured by the setting data of R, setting data of G and setting data of B. Use ASCII letters code to set the grade for setting data. Please refer to the table below for HEX code.
ASCII | '+' | 'Å' | '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9' |
HEX | 2Bh | 2Dh | 30h | 31h | 32h | 33h | 34h | 35h | 36h | 37h | 38h | 39h |
[Example 1] Set the setting data of R to +10, the setting data of G to 0 and the setting data of B to
