Add FPGA/output_files/LEDTile.sof and NIOS_II_SOFTWARE/LEDTileSerialAPIApplication/LEDTileSerialAPIApplication.elf.Turn on menu option Options->Run From Reset After Programming.Open the menu Nios II->Flash Programmer.Connect a USB cable to the DE0 Nano FPGA board.To write it to the serial configuration device: Right click LEDTile_BSP2 then go Nios II->Generate BSPīuild LEDTileApplication and write it to the serial configuration device using the Flash Programmer under the NIOS II menu. The Board Support Package will likely need to be regenerated. Open the Eclipse tools for Nios II and create a new workspace, and add all of the projects in It can be build and converted into a programming file then loaded into the serial configuration device over USB. LEDTile.qpf is the Quartus project file and should be opened in Quartus.

Here is a high level diagram of the logic implemented in the FPGA: 64Mb EPCS64 serial configuration device.Of interest to this project, the board contains. ESP8266 WiFi SoC serving an HTTP API for control of the unit.My custom circuit board the provides a place to hook up the FPGA and LED tile to, and supplies power.Nios II core CPU for transferring graphics into the pixel buffer.Logic for pushing a memory pixel buffer to the tile and managing the timing of the R, G, and B LED components to create the illusion of colour mixing.PlatformIO to build the ESP8266 firmware.My circuit or something else to power the board and FPGA and connect them together.A Terasic DE0-Nano FPGA or something like it.New ESP8266 firmware can be done over the air, but the FPGA configuration and Nios II are loaded over a USB cable. Uses a Terasic DE0-Nano FPGA with a Nios II core soft CP running the Micrium μC/OS-II RTOS kernel, a custom circuitboard, and an ESP8266 serving an HTTP API for controlling it. This is an FPGA-driven WiFi connected 32x32 LED tile that I hang on my wall.
