1 | Some LCDs allow you to define up to 8 characters, mapped to ASCII |
2 | characters 0 to 7. The escape code to define a new character is | |
3 | '\e[LG' followed by one digit from 0 to 7, representing the character | |
4 | number, and up to 8 couples of hex digits terminated by a semi-colon | |
5 | (';'). Each couple of digits represents a line, with 1-bits for each | |
19f59460 | 6 | illuminated pixel with LSB on the right. Lines are numbered from the |

7 | top of the character to the bottom. On a 5x7 matrix, only the 5 lower |
8 | bits of the 7 first bytes are used for each character. If the string | |
9 | is incomplete, only complete lines will be redefined. Here are some | |
10 | examples : | |
11 | ||
12 | printf "\e[LG0010101050D1F0C04;" => 0 = [enter] | |
13 | printf "\e[LG1040E1F0000000000;" => 1 = [up] | |
14 | printf "\e[LG2000000001F0E0400;" => 2 = [down] | |
15 | printf "\e[LG3040E1F001F0E0400;" => 3 = [up-down] | |
16 | printf "\e[LG40002060E1E0E0602;" => 4 = [left] | |
17 | printf "\e[LG500080C0E0F0E0C08;" => 5 = [right] | |
18 | printf "\e[LG60016051516141400;" => 6 = "IP" | |
19 | ||
20 | printf "\e[LG00103071F1F070301;" => big speaker | |
21 | printf "\e[LG00002061E1E060200;" => small speaker | |
