Powered by an RP2040 and a Lattice iCE40UP5K, made by Ryan Hausmann. Please note that everything was tested on Ubuntu running on Windows through WSL.
Please note that this design has not been tested on actual hardware yet.

This is enough to do simulation with Verilator and SDL. To install the synthesis tools and the Pico SDK, run ./install_synthesis.sh.
Synthesis is handled by Yosys and Project Icestorm. The Pico firmware is compiled using cmake & pico-sdk.
The FPGA configuration is packaged into the RP2040 program. The build/ili9341_controller.uf2 file can be built with make or make pico. This will compile the RP2040 program and also automatically build the FPGA configuration, with the files stored in the build directory.
On Windows, the generated uf2 file can be dragged into the Pico's drive folder.
Simulation has been implemented with Verilog and SDL.
To build the simulation program, run make verilator.
To run the simulation program, run ./build/Vili9341_controller. The program will not do anything useful by default, but all the options can be viewed with the --help argument.
To show the simulated screen output, run ./build/Vili9341_controller --screen-sim. The --screen-scale argument can also be used to scale the screen, the default is 1x (240x320 px).
Below is a screenshot of a simulation with letter sprites:
make clean will remove all build files. The dependencies will remain in the dep folder.
All KiCad files for the PCB are in the pcb folder. Click here to download the current schematic as a PDF (pcb/sch.pdf).
