5 | Some LCDs allow you to define up to 8 characters, mapped to ASCII |
6 | characters 0 to 7. The escape code to define a new character is | |
7 | '\e[LG' followed by one digit from 0 to 7, representing the character | |
8 | number, and up to 8 couples of hex digits terminated by a semi-colon | |
9 | (';'). Each couple of digits represents a line, with 1-bits for each | |
19f59460 | 10 | illuminated pixel with LSB on the right. Lines are numbered from the |
7005b584 WT |
11 | top of the character to the bottom. On a 5x7 matrix, only the 5 lower |
12 | bits of the 7 first bytes are used for each character. If the string | |
13 | is incomplete, only complete lines will be redefined. Here are some | |

18 | printf "\e[LG2000000001F0E0400;" => 2 = [down] | |
19 | printf "\e[LG3040E1F001F0E0400;" => 3 = [up-down] | |
20 | printf "\e[LG40002060E1E0E0602;" => 4 = [left] | |
