RDS ( Radio Data System ) is a communication protocol standard used for embedding small amounts of digital information in traditional FM radio broadcasts. It enables radio stations to transmit data such as station identification, program information, and traffic updates.  To capture and decode RDS data, one method involves using a Software Defined Radio (SDR) along with GNU Radio and RFtap . GNU Radio provides a framework for creating software radios, while RFtap acts as a bridge between GNU Radio and conventional network monitoring and packet analysis tools like Wireshark . Decoding RDS data using Wireshark. Unfortunately, as of the time of writing, RFtap is no longer being maintained and does not work with the latest version of GNU Radio (version 3.10.10). This post offers guidelines for rebuild and using RFtap with the new GNU Radio release. This post assumes that the reader has access to DVB-T dongles based on the Realtek RTL2832U and a PC running Ubuntu or Debian Linux. For ...

LiteASM is a Light weight and reconfigurable Assembly language compiler and Virtual Machine. It is design to fulfill the following core requirements: As a scripting interface for embedded systems. As a cross platform scripting interface. As a experimental tool for compiler construction. LiteASM compiler is design with minimum static instruction set. Its dynamic instruction set can be easily extend using compilers configuration files. LiteASM compiler generate fixed length binary output file and it can execute on LiteASM Virtual Machine Simulator ( litevm ) or on top of platform specific virtual machine. Virtually LiteASM Virtual Machines can execute on any 8bit to 64bit CPU/MCU/DSP platform. 8bit version of Fibonacci series demo on LiteASM Virtual Machine Simulator LiteASM compiler and Virtual Machine simulator are distribute as a free and open source software (under the terms of GNU GPL version 3.0 ) and available for both Windows and Linux operating systems. This Lite...
