Wireless LAN Application Guide

Introduction
These examples demonstrate the use of the Flowcode Wireless LAN component.
In particular they make use of the EB069 E-blocks Wireless LAN board and EB006 E-blocks PICmicro multiprogrammer fitted with a 16F1937 microprocessor.
However, the examples are easily changed in Flowcode to support other microprocessors and platforms.
The Matrix TSL EB868SI6 Easy Wireless LAN bundle has all the items required for these sample applications and is an ideal introduction to Wireless internet technology.
Setting up the project hardware
Connect the E-Blocks as indicated in the table below. All the downstream E-Blocks, apart from the LED board, need to be powered via wire connections to the +V on EB006 upstream processor board.
| EB006 | PICmicro multiprogrammer | |
| Port A | EB090 | E-blocks Sensor board |
| Port B | EB005 | E-blocks LCD board |
| Port C | EB069 | E-blocks WiFi board |
| Port D | EB004 | E-blocks LED board |
Example 1: Using the Wireless LAN as a web page server
Example 1 demonstrates the use of the WLAN component as a web server. The server is initialised and then the program enters a infinite loop where the value of the Light sensor on the Sensor E-block is read into a variable. The CheckForPageRequests macro function is be called as part of the main program loop as this allows remote page requests to be detected and serviced.
