FPGA Colors Palette Tester Version 1 by Timothy Stotts
A small FPGA project of Xilinx IPI-BD with Microblaze CPU implementations for testing 24-bit color palette mixing of discrete RGB LEDs versus 16-bit color palette mixing of a 96x64 OLEDrgb display’s text. The design targets the Digilent Inc. Arty-A7-100T FPGA development board containing a Xilinx Artix-7 FPGA. Two peripherals are used: Digilent Inc. Pmod KYPD, Digilent Inc. Pmod OLEDrgb.
The folder Color-Tester-Design-AXI contains a Xilinx Vivado IP Integrator plus Xilinx SDK design. A Microblaze soft CPU is instantiated to talk with board components, a 4x4 alphanumeric keypad, and 96x64 pixel color display. A Xilinx SDK project contains a very small Standalone program in C; drivers for the peripherals; and a main loop to repeatedly read keypad entry and then update both discrete LEDs and display.
