We want to use lcd display with ROS to show many usefull informations, but to take full control on this lcd with serial controler, We must send via serial port ascii char #27 (ESC) . Now we only use :
\a bell (alarm), character code 7
\b backspace, character code 8
\f form feed, character code 12
\n newline, character code 10
\r carriage return, character code 13
\t tabulation, character code 9
\v vertical tabulation, character code 11
_ space, character code 32
But there isn’t char #27.
Help, it is very important for us.
Mayeby someone now how to do it.
