#Describes Configuration file syntax for SerialChart application (.scc files)

Introduction

SerialChart configuration is done through a text file. The general format of the file is as follows:

[section1]

param2 = value

Setup Section

Each configuration file starts with the [_setup_] section, here you can setup global parameters. For

example:

[_setup_]

port=COM3

baudrate=57600

width=1000

height=201

grid_v_origin = 0

grid_v_step = 10

grid_v_color = #EEE

grid_v_origin_color = transparent

Below are the parameters that can be used in the [_setup_] section:

port

Specifies the communication port to which the software connects. For ex: COM1,COM2,..

baudrate

Baudrate in bps (bits per second). Only certain values are currently supported:

Background color of the chart.

Note about color formats Please note that colors in .SCC files can be specified in hex format (for

ex: #FFF, or #FFFFFF) or named color (white,blue,magenta,pink,gray)

see:http://www.w3.org/TR/SVG/types.html#ColorKeywords . Please note the special

value transparent which means "no color". You can use it if you don't want some elements to be

drawn at all.

grid_h_origin, grid_v_origin

Both horizontal and vertical grids will have an origin axis line, usually of different color from the

regular grid lines. These parameters specifies the shift of this line from top/left borders of chart in

pixels.

Default and Field Sections

SerialChart accepts packets in CSV format (other formats might be supported in the future). Each

packet comes on a separate line and each field value is separated by comma. Here is an example of

sample data that SerialChart would receive:

100,0.50,0.70

101,0.30,0.50

102,0.25,0.35

The purpose of the following sections in the configuration file is to specify parameters for each field

in the packet. For example:

[_default_]

max=255

[Field2]

color=blue

[Field3]

color=red

You can specify parameters that would apply by default to all fields in the [_default_] section.

These parameters will apply to all field sections unless they will be overridden in the field section by

parameters with the same name.

names _setup_, _default_. For that matter avoid any names that start and end with _.

Below is an explanation of the parameters accepted in the [_default_] and field sections:

min,max

These are the field values that correspond to the top and bottom lines of the chart. In other words if

you specify min = -1 and max = 1. A value of -1 will be plotted at the top border of the chart , and a

value of 1 will be plotted at the bottom border of the chart. A value of 0 (which is is the midpoint

between -1 and 1) will be plotted at the middle of the chart. Field values are linearly mapped

from [min,max] range to [0,height] range where height is the chart height in pixels, specified in the

setup section.
