GbHdmi

HDMI version of project GbVga, aim to display GameBoy (DMG) on HDMI screen and play with Super NES Joypad.

This project aim to demonstrate the HDMI feature of Gowin FPGA on Tang Nano 4K and the power of Chisel HDL language for hardware generation.

• Demonstration in video.
• Demonstration in video with Super Nes Joypad.

#GbHdmi was awarded at the Digitronix Nepal competition.

Dependances

To generate the core some additionnal Chisel library are required to be published locally :

• GbVga:

$ git clone https://github.com/Martoni/GbVga.git
$ cd GbVga/chisel/
$ sbt publishLocal

• fpgamacro:

$ git clone https://github.com/Martoni/fpgamacro
$ cd fpgamacro
$ sbt publishLocal

• HdmiCore:

$ git clone https://github.com/Martoni/HdmiCore
$ cd HdmiCore
$ sbt publishLocal

• chisNesPad:

$ git clone https://github.com/Martoni/chisNesPad
$ cd chisNesPad
$ sbt publishLocal

Core generation

To generate verilog using HdmiCore :

$ sbt "runMain gbhdmi.TopGbHdmiDriver

Verilog BlackBoxed sources are available in directory src/verilog and pinout/constraints in src/constraints.
