Introduction

Sending data over short distances wirelessy is forever being made simpler. Integrated circuits are not only providing most of the RF circuitry, but also protocol layers to provide reliable links.

Nordic Semiconductor provide a rich suite of IC's for conveying information over the airways. The NRF24Z1, as used in the wireless audio project, was used to transmitt audio data.

For general wireless communcations a better offering is the nRF24L01. This IC allows data to transmitted up to a rate of 2Mbits/s. Unlike the nRF24LZ1 the data transfer rate can be symmetrical.

The overall goal of this project is to combine the uCEthernet module, an LPC2106 and a nRF24L01 to monitor two temperatures. The two values will be used to update a webpage that can be accessed anywhere.

Project Setup

This project can be broken down into the following top level task.

  1. Design and build the nRF24L01 module.
  2. Write firmware to test the nRF24L01 module.
  3. Update uCEthernet code to support http server.
  4. Combine all of the above.
