Device OUTPUT Configuration
Define a device output descriptor (SPAD -> Device)
For defining an output descriptor the following command syntax is used:
<DeviceIndex> is the numercial index the output should be used by SPAD when sending updates to the device (See LED / DISPLAY update ). For Led commonly the pin on the device can be used as <DeviceIndex>. This way no more internal processing needs to be done on the device. The <DeviceIndex> should be unique per <Type>
<Tag> being the internal name SPAD.neXt should use for events bound to that output descriptor. <Tag>'s must be unique device wide. It's generally a good idea to give the <TAG> a prefix (e.g. L_ for led and D_ for Displays)
<Type> the type of the output descriptor Currently there are two types of output descriptors supported:
LED an led that has either only a ON/OFF state or a multi color LED
DISPLAY any kind of display
<Inherits> is a list of base configurations the output shall use within SPAD.neXt. This decides about the events available for the output and the behaviour.
Device output LED
A led is a simple output descriptor that always has at least the state ON or OFF
Available <Inherits> for led
SPAD_LED a simple ON/OFF led
SPAD_LED_3COL a 3 color led predefined as Red,Green,Yellow
SPAD_LED_C a led with custom defined colors. The option COLORSET=<Colorset_Index> must be added to the command to inform SPAD.neXt about the available colors.
Available specific options
DYNLABEL=1 | Enabled updates of the led-labeltext (UI_FACE=2) via events | |
UI_FACE=0 | A round led that changed fillcolor depending on it's state | |
UI_FACE=1 | A rectangular led that changes foreground-color depending on it's state |
|
UI_FACE=2 | A rectangular led that can change fore/background depending on it's state |
|
UI_FACE=3 | Use custom provided images | |
NOIMG=1 | No background image | |
COL_0 | Color of OFF in UI (UI_FACE != 3) | LightGray |
COL_1 | Color of ON in UI (UI_FACE != 3) | Yellow or #FFFF00 |
IMG_OFF | Image for OFF (UI_FACE = 3) | _PanelImages/LED_OFF.png |
IMG_ON | Image for ON (UI_FACE = 3) | _PanelImages/LED_ON.png |
Examples
0,OUTPUT,1,L_LED1,LED,SPAD_LED; defines a ON/OFF led with tag L_LED1 and index 1
0,OUTPUT,2,L_LED2,LED,SPAD_LED_3COL; defines a 3-color led with tag L_LED2 and index 2
0,OUTPUT,3,L_LED3,LED,SPAD_LED_C,COLORSET=1; defines a custom led with tag L_LED3 and index 3 using the defined colorset 1 (See COLORSET)
Device output DISPLAY
A display is any kind of alphanumerical output. It can e.g. be a 7-Segemnt lcd or a complex display with 5 rows of 20 characters each
The only available <Inherits> for a display is
SPAD_DISPLAY
All configuration is done via the options:
| Option | Value | Description |
|---|---|---|
LENGTH | integer | Length of each row in characters |
ROWS | integer | number of rows |
SEGMENTS | integer | number of segements per row. Each segments will be LENGTH/SEGEMENTS width (Default: 0) |
DEFAULT | any | Default value to display |
NOPADDING | 0|1 | Disable padding and aligment of output values |
NOSEGMENTROWEVENTS | 0|1 | SPAD will only send updates per row, not per segment |
SEGMENTALIGN | LEFT|RIGHT (... per segment) | Alignment of segment value (Default: Right) |
TEXTALIGN | LEFT|RIGHT | Aligment of row (Default: right) |
| string | Name of the font to use (Default: Builtin LCD Font) |
FOREGROUND | #RRGGBB | Forground color (Default: Blue #FFF0F8) |
BACKGROUND | #RRGGBB | Background color (Default: Black #000000) |
FONTSIZE | number | Size of the UI font (Default: Height of one display row) |
HEIGHT | number | Height of display in pixels (UI) |
WIDTH | number | Width of display in pixels (UI) |
Examples
0,OUTPUT,1,D_1,DISPLAY,SPAD_DISPLAY,LENGTH=6,ROWS=1,WIDTH=133,HEIGHT=40
0,OUTPUT,1,D_1,DISPLAY,SPAD_DISPLAY,LENGTH=15,ROWS=3,WIDTH=350,HEIGHT=120
0,OUTPUT,1,D_1,DISPLAY,SPAD_DISPLAY,LENGTH=24,ROWS=12,WIDTH=400,HEIGHT=300,FONTSIZE=16
Other outputs
Forany other kind of output (e.g. a servo) no output needs to be defined. Just provide a RW-data for the output using the ADD command and act on the device accordingly to changes to that data
