Macro reference

SetOutValue
Set the value of an outbound substitution string 
- BYTE index
 
- STRING value
 
- VOID Return


Send_Embedded_HTML_Page4
 
- VOID Return


Send_Embedded_HTML_Page3
 
- VOID Return


Send_Embedded_HTML_Page2
 
- VOID Return


Send_Embedded_HTML_Page1
 
- VOID Return


GetInValue
Returns the string value of a Request parameter 
- BYTE index
 
- STRING Return


CreateServerSocket
Creates a listening socket on the selected channel and port ready to accept incoming web page requests. 
- BYTE Channel
 
- BYTE Port_Hi

- BYTE Return


IncRxPtr
 
- BYTE Channel
 
- VOID Return


CheckSocketActivity
Checks for activity on the server socket and serves out the webpages to any requesting parties.

Property reference

Properties
Label
Label used to help identify the component on the panel. 
Max Channels
Max number of concurrent channels allowed 
I2C Address
I2C address of the module - bit 0 
HTML Source
HTML Source
Sets the method for streaming data, we can either host it loacally using a property or refer to external files. 
Max Pages
Maximum number of pages we can serve using the embedded page type webserver. 
Name Page 1
Name of HTML page 1 - index.htm is the default page that will be presented. 
HTML Page 1
Embedded HTML code used for page 1 
Name Page 2
Name of HTML page 2 
HTML Page 2

Connections
Channel
Channel selection 
Baud Select

Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
