• Turning on channels 1 through 254 enables transmission (RF or IR) of
the respective radio code. The code example below transmits radio
code 128 when button 1 is pressed.

• Use SEND_STRING to send characters to the LCD screen. Characters
will start at the current cursor position.
• Special SEND_STRING escape sequences are included in the TX–
MLCD commands. When included within a SEND_STRING program
instruction, the following character combinations will be treated as
commands:
— "2" moves the cursor to home (line one, column one)
— "9" moves the cursor one position right
— "10" moves the cursor one position down (to next line)
— "12" , clears the screen and moves the cursor to home (line one,
column one)
— "13" moves the cursor to first of line (column one)
— "17,<line number>,<column number>" moves the cursor to the
specified line and column
• When a button is pressed, the TX–MLCD unit powers-up and runs
through the DEFINE_START section. The DEFINE_START section is
the part of the program where the text for each of the screens is setup
and initialized.
With the text already initialized, the main part
(DEFINE_PROGRAM) of the program is shorter and simpler
allowing you to flip from one screen to another with a
SEND_STRING command.
