Please post your recommendations or critiques of projects sites concerning Manchester Encoding/Decoding.

I'm always on the lookout for any online Manchester SubGHz/RF resources.

One recommendation is the following site:

Manchester Encoding
 

This tutorial is about using licence free radio modules, most countries now have such modules available at low cost, although the exact frequencies may vary between different countries. The tutorials utilize Manchester Encoding/Decoding.


PIC Tutorial Twelve - RF remote control
 

The following PDF takes a look at transporting Manchester encoded data using RS232, over a radio frequency (RF) link:

When commercial options fail, try using Manchester encoding and other time-tested protocols in low-cost, low bit-rate serial communications.

When beginning to work with communication systems, it is important to first understand a few basic terms that are used, Modulation and Coding. These are often used interchangeably which leads to many errors because they refer to completely different aspects of the communication. It is very important to observe and fully understand the application and implementation of these two aspects of communication theory. This application note will be focused on the Coding and Decoding. But, before we address this, we need to look at what must be done to send a message or data through our communication system.

Manchester Coding Basics - Atmel Appnote
 

The objective of this document is to demonstrate the Table of Contents feasibility of using the XGATE programmable peripheral on the HCS12X microcontroller family as a Manchester decoder for radio frequency (RF) receiver applications. The XGATE is a reduced instruction set computing (RISC) peripheral that allows data transfers between peripherals and internal RAM. The process of decoding Manchester-coded signals requires intensive interrupt servicing from timer inputs, as well as high central processor unit (CPU) loading.
