RC-6 is, as may be expected, the successor of the RC-5 protocol. Like RC-5 the new RC-6 protocol was also defined by Philips. It is a very versatile and well defined protocol. Because of this versatility its original definition is many pages long. Here on my page I will only summarize the most important properties of this protocol.

I've collected and combined some information found on the internet about the Sony SIRC protocol. I must admit that I have never worked with this particular protocol, so I could not verify that all information is valid for all situations.
It appears that 3 versions of the protocol exist: 12-bit (described on this page), 15-bit and 20-bit versions. I can only assume that the 15-bit and 20-bit versions differ in the number of transmitted bits per command sequence.

The RC-5 code from Philips is possibly the most used protocol by hobbyists, probably because of the wide availability of cheap remote controls. The protocol is well defined for different device types ensuring compatibility with your whole entertainment system. Lately Philips started using a new protocol called RC-6 which has more features.

I only have little information on this protocol. It is used in VCRs that are produced by Sharp, that is why I gave it the name Sharp protocol.

    8 bit command, 5 bit address length
    Pulse distance modulation
    Carrier frequency of 38kHz
    Bit time of 1ms or 2ms

  • Communication


    For communication with outside world and other components microcontroller uses many different kinds of communication. Here you will find detailed explanation on how each of these communication protocols. Details of principles how the work, what you must know before you can use them. And when finished here you can go to tutorial sections for specific family and get complete example codes and detailed description on specific microcontroller family. These are UART, I2C, SPI, USB…


  • Measurement


    Basic functions that every device does are measurement and control. That is why it is important to know how to properly measure something and what sensor to use.. Here you will find explanations on these topics to help you with implementing hardware for your microcontroller project.


  • control


    As previously mentioned Control is one of most important things in every project. Weather you need to control some DC motor using PWM, timer circuits with NE555, Using servo motors, Using PID regulation or any kind or regulation you will find useful articles here describing basic term from this are that you need to know before you can start making your project. Here are mentioned only few of areas this category of covers. PLL frequency regulation… list is endless. When you get the basics you can get example codes written in microcontroller C compiles on tutorials page or find complete project with source code and all documentation in projects section of the site.
