Uploading pages to the server
files you want to upload in a MPFS file format. One other way is to include the web page on the
source code and link it in a project, but if we did it in this way we won’t use the EEPROM included in
the platform wasting program memory, that is reason this method will not be included in this manual.
embedded system. That is why it is necessary to transform the files to that file system before
uploading them. This is done using a program included in PIC-WEB software called MPFS2.exe.
upload to the web server. The “index.htm” is a must have file because that is the default page read by
the server. We will also upload a picture “olimex.gif” (get it from the site for example). The code of the
page is the simplest possible:
Buttons:
Potentiometer:
Temperature:
At the page you can also see some values of the PIC-WEB sensors and buttons:
“Potentiometer” shows a measurement from the PIC A/D connected to a 10KΩ potentiometer
“Temperature” shows the value of the temperature sensed by the thermistor in the board
“Buttons” shows the state of the on-board button. It is “^” while the button is not pressed and
There are 2 easy ways to upload pages to the server, but you will always need to convert the

The implemented HTTP server uses the MPFS simplified file system to store the pages on the
Let’s create a simple “Hello World” page and upload it in to the HTTP server.
First of all it’s necessary to create a directory on your PC where to put the files you want to
