# 3D Maze Game
|
||||
|
||||
Based on: <https://github.com/programmerjake/rv32/tree/v0.1.0.1-alpha/software>
|
||||
|
||||
# Run without FPGA/hardware-simulation
|
||||
|
||||
Resize your terminal to be at least 100x76.
|
||||
|
||||
Building:
|
||||
```bash
|
||||
cd usb_3d_game
|
||||
make usb_3d_game_emu
|
||||
```
|
||||
|
||||
Running:
|
||||
```bash
|
||||
./usb_3d_game_emu
|
||||
```
|
||||
|
||||
# Run on OrangeCrab v0.2.1
|
||||
|
||||
Set the OrangeCrab into firmware upload mode by plugging it in to USB while the button is pressed, then run the following commands:
|
||||
|
||||
Building/Flashing:
|
||||
```bash
|
||||
(cd usb_3d_game; make)
|
||||
sudo make FPGA_TARGET=ORANGE-CRAB-0.21 dfuprog DOCKER=1 LITEDRAM_GHDL_ARG=-gUSE_LITEDRAM=false RAM_INIT_FILE=usb_3d_game/usb_3d_game.hex MEMORY_SIZE=$((1<<18))
|
||||
```
|
||||
|
||||
Then, in a separate terminal that you've resized to be at least 100x76, run (replacing ttyACM0 with whatever serial device the OrangeCrab is):
|
||||
```bash
|
||||
sudo tio /dev/ttyACM0
|
||||
```
|
||||
|
||||
# Controls
|
||||
|
||||
Use WASD or the Arrow keys to move around. Press Ctrl+C to quit or restart.
|
||||
|
||||
The goal is a set of flashing blocks, nothing special yet happens when you reach them though.
