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 ...

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 ...

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 ...

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 ...

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 ...
