• 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.
