Serial Protocol

Parameter: 38400 baud, 8 bit, no parity, 1 stop bit

stream commands

<*> [ESC]c - clear display
< > [ESC]r - repeat begin
< > [ESC]s - repeat start
<*> [ESC]b{n} - set matrix brightness to n=[0-9: 0-90%, *: 100%]
<*> [ESC]d{n} - dimm matrix brightness to n=[0-9: 0-90%, *: 100%]
< > [ESC]o{x} - set matrix orientation x=[n,w,e,s: North, West, East, South]
<*> [ESC]t{c} - transmit back char (synchronisation) c=[ASCII char]
<*> [ESC]l - load next matrix bytes without delay
    font modifiers:
< > [ESC]e1 - economy font size (3×6)
< > [ESC]e0 - normal font size (5×8)
< > [ESC]i1 - inverted output
< > [ESC]i0 - noninverted output
< > [ESC]p1 - proportional mode
< > [ESC]p0 - fixed width mode


<*> [ESC]B{xxxxxxxx}[SPACE] - Bargraph mode, every char is a colon, terminated by space
<*> [ESC]G{xxxxxxxx}[SPACE] - Grafic mode, bytes are hexadecimal encoded, terminated by space
<*> [ESC]P{xxx}[SPACE] - Pause given time in miliseconds
<*> [ESC]S{xxx}[SPACE] - set shift delay time (ms)
<*> [ESC]D{xxx}[SPACE] - set matrix dimm transition time (ms)
<*> [ESC]T{n}{xxx}[SPACE] - matrix dimm transition value and time
< > [ESC]X{xxx}[SPACE] - hexadecimal to decimal conversion


immediate commands

<*> [DLE]c - clear and reset display
<*> [DLE]d{n} - set matrix dimm value to n=[1-9: 10-90%, 0: 100%]
< > [DLE]o{x} - set matrix orientation x=[n,w,e,s: North, West, East, South]
