Overview

ASIC GPU testing app written in C run on Windows.
To be able to run on different OS, you may need to use different UART library.
The app will send these data, 60 bytes, each frame @11520 baud rate to the GPU

• 4 vertices world coordinate that form a quad
• 1 normalize normal
• 1 normalize light direction
• 3x4 ModelViewProjection matrix. (third row is not used)
• 1 byte render mode
  • solid shading, texture, alpha masked

The data are in the format of fixed point Q8.8 except for the 1-byte render mode.
The code has been successfully tested with the Basys3 board, sending data at 60fps.

How to use

1. The code rely on SFML library for the input and windows. https://www.sfml-dev.org/tutorials/2.6/start-vc.php.
   Please install SFML first.
2. Change the COM port number in C code to match with the ASIC/FPGA port
3. short cut keys
   • arrow key: yaw pitch
   • as: zoom
   • df: change model size
   • er: X translation
   • 012: render mode
   • 34: change texture
   • 6789: change triangle 1 color
   • uiop: change triangle 2 color
