  • Recreating Nintendo Chiptunes with FPGA and the 6502 processor

    Greetings FPGA lovers! Today’s project explores the possibility of using FPGA in combination with other processors to recreate the amazing Nintendo Chiptunes or Soundtracks that an entire generation of gamers are used to. The project uses a combination of FPGA with Verilog and the 6502 processor along with a Nesdev APU for audio generation. The…

  • Critical Tips to Build Your Own C88 Homebrew Computer with FPGA

    Greetings FPGA lovers! Today’s post is about building your own mini computer using FPGA. The project has been inspired by the first SSEM, popularly called the Manchester baby. The project resembles its inspiration in certain aspects, but being a homemade CPU with minimal components and coding, the specs are not as formidable as the SSEM.…

  • How to Synthesise Music with YM 2151

    Hello FPGA lovers! Today we are going to share another instalment of our YM 2151 post series. According to the author of the original article (in Spanish), the best way to produce sound using the YM 2151 is to use the 6809 assembler which is a cross targeting assembler seen usually in Motorola and Hitachi…

  • Using the YM 2151 for Noise Generation

    Hi there FPGA lovers! Here we have another release of our series of YM2151 posts. To recreate the YM 2151 in FPGA using VHDL, every aspect of the YM 2151 needs to be mapped on to the recreation platform. However an interesting aspect regarding the YM 2151 is that it uses random values for generation…

  • Understanding the YM 2151- YM 3012 Relationship

    Hi FPGA lovers! In our conquest to find studio quality sound, we stumbled upon the YM 2151 FM Synth Chip which has been used by Yamaha from time immemorial in a number of their electronic keyboards and arcade games. The YM 2151 has a Digital output rather than an analog output and this makes it…

  • Create Studio Quality Sound with YM 2151 and FPGA

    Hello FPGA lovers! Today’s post is about making real studio quality music rather than the monotone buzzers from conventional circuits. FPGAs can be used to create monotone sounds such as beeps by using the right combination of DACs and buzzers. However these devices cannot be used to create studio quality sound that not only plays…

  • How to Build an Automated Intelligent Room Lighting System with FPGA

    https://youtu.be/k5gNt69FuBU Hello FPGA lovers! The project in focus today is aimed at creating an Intelligent Room Lighting System with FPGA, where you can bid adieu to the use of switches! The system is powered by an FPGA board connected to a set of LEDs that turn on depending on the number of people in the…

  • 9 Steps to Create a LED FSM to Measure Power with FPGA

    Hi there FPGA geeks! Power monitoring is a big step when it comes to analysis and subsequent models used for power conservation. The project for today is building an FSM (finite state machine) with a LED as its output and FPGA as its core to measure the power output by the LED when it is…
