HSC301 Rolling Code Remotes Programmer v06.1

HSC301 Rolling Code Remotes Programmer v06.1
After some busy months/years 🙂  I needed to recover the code of my Arduino based “HSC301 Rolling Code Remotes Programmer”, mainly because of a failure on my prototype, that I’m not sure yet which was… The changes I made after that were to put a new prototype working again! I hope you can still enjoy the ...

RF Receivers Analisys

RF Receivers Analisys
To be one of the major components of our prototype Receiver, we decided to analyse a bunch of RF Modules, in order to be sure to select the best performance unit and the best performance/cost unit, for our both premium and cost optimized receivers. This is still a work in progress, but we can already ...

Remotes Encoding Analisys

Remotes Encoding Analisys
As part of the development, we start analysing the maximum possible quantity of remotes. Bellow you can found a picture of the differences between some of the encoding chips available.   A functional prototype of our Universal Remotes Receiver (RXU01) is already running and under tests, and it is demonstrating good compatibility with almost all ...

Importance of Fixed Frequency Remotes

Importance of Fixed Frequency Remotes
We have previouslly talked about the Fixed vs Adjustable Frequency Remotes. The following Printscreen show you how badly work an Chinese adjustable frequency remote. Depending on your hand position, the output frequency will vary. It also vary between remote buttons, and shift during a single button press. Lest’s Remember it the technical differences: MAJOR DIFFERENCES ...

Encoding Chips Documentation

Encoding Chips Documentation
As important part of this journey, study of available Encoding Chips Documentation was a major milestone. We have collected a bunch of those datasheets that you can found bellow. On next blogs we will provide some examples available online to implement decoders of various types. Some of them are compatible with 2 types of encoding ...

Identify your Garage Door Encoding Chip
Overview – Typical RF Remote Control PCB Layout A typical RF remote control’s PCB is comprised of many electronic components, such as SAW resonator which controls the transmitting frequency and encoder IC which encodes the transmitting data. The typical inner photo of RF remote control is listed as follows.

If you are looking for the first time to this topic, you probably never realized how many different types of RF encoding technologies exist. They are mainly 3 types of techniques developed in the past decades: Fixed Code Computer/Learning/Million Code Rolling Code Each technique have been used by different manufacturers with different encoding implementations. Fixed ...
