-Message format is:
- <SEQ><CMD><CMD><CMD> ... <ZERO>
-
-Where:
- <SEQ> is a two byte sequence count
- <CMD> is a series of bytes as follows:
- <LEN><COD><PARAMS>
-
-Where:
- <LEN> is a two byte with value 1..65535 depicting msg len
- <COD> is a one byte command code - see below
- <PARAMS> are a series of bytes containing the parameters for the command
-
-<COD> values:
-
- NOTE MSB of COD is used to indicate that no response is required on success
- i.e. if MSB of COD is 1 then no response is required on success
-
- (COD & 0x7f) ....
- 0x01:
- Clear the entire strip
- There are no parameters
- 0x02:
- Fill a series of leds with RGB values
- <PARAMS> := <START><NUM><RGB1><RGB2>
- Where:
- <START> is a two byte value (bigendian) for led to start series
- <NUM> is a two byte (bigendian) number of leds to set
- <RGB1> is the starting RGB value (24bits)
- <RGB2> is the ending RGB value (24bits) - OPTIONAL
- The RGB2 value is optional - the LEN value determines whether it is present or not
- - if present the colour values are interpolated (HSV) between RGB1 and RGB2
- - if not present all leds are set to colour RGB1
- 0x03:
- Detect LED with opto-sensor (put opto-sensor on LED and run command)
- Sensor must be attached to p20 - currently using BPX65 with 470K pullup
- Returns string with LED number
- 0x04:
- Set number of leds and split point
- <PARAMS> := <NUMLEDS><SPLITPOINT>
- Where:
- <NUMLEDS> is a two byte (bigendian) value for number of leds in strip
- <SPLITPOINT> is a two byte (bigendian) value for point at which DigitalOut(p10) is used instead of p12 for data
- (this is because the spidey wall is two parallel chains of LEDS)
- 0x05:
- Raw RGB values for a series of leds
- <PARAMS> := <START><NUM><RGB1><RGB2><RGB2>....<RGBn>
- Where:
- <START> is a two byte value (bigendian) for led to start series
- <NUM> is a two byte (bigendian) number of leds to set
- <RGB1> is the RGB value for 1st LED (24bits)
- <RGB2> is the RGB value for 2nd LED (24bits)
- <RGBn> is the RGB value for nth LED (24bits)
- 0x06:
- Set colour for leds on a pad
- <PARAMS> := <PAD><RGB1><RGB2>
- Where:
- <PAD> is the pad number (1 byte)
- <RGB1> is the starting RGB value (24bits)
- <RGB2> is the ending RGB value (24bits) - OPTIONAL
- The RGB2 value is optional - the LEN value determines whether it is present or not
- - if present the colour values are interpolated (HSV) between RGB1 and RGB2
- - if not present all leds are set to colour RGB1
- 0x07:
- Set node and link info
- <PARAMS> := <NODE><NODEFLAGS><NODERGB><LINKIDX><LINKLEDSTART><LINKNUMLEDS><LINKRGB>
- Where:
- <NODE> is the node number (1 byte)
- <NODEFLAGS> LSB is 0 if the RGB value for the node is not to be changed, or 1 otherwise (1 byte)
- <NODERGB> is the RBG value for the leds in the node itself (3 bytes)
- <LINKIDX> is the index of the link (edge) from this node to control (1 byte)
- <LINKLEDSTART> is the LED along the link to start controlling (1 byte)
- <LINKNUMLEDS> is the number of LEDs to control (1 byte)
- <LINKRGB> is the colour to make the link LEDs (3 bytes)
-
- 0x08:
- Raw HSV values for a series of leds
- <PARAMS> := <START><NUM><HSV1><HSV2><HSV3>....<HSVn>
- Where:
- <START> is a two byte value (bigendian) for led to start series
- <NUM> is a two byte (bigendian) number of leds to set
- <HSV1> is the RGB value for 1st LED (16bits) - first 8 bits = H, upper 4 (bigendian) = S / 16, lower 4 = V / 16
- <HSV2> is the RGB value for 2nd LED
- <HSVn> is the RGB value for nth LED
-
- 0x09:
- ShowLeds
- Until this command is sent all other commands simply "paint" into the buffer and don't actually change the LEDs
- There are no parameters
