# learn-fpga 
_Learning FPGA, yosys, nextpnr, and RISC-V_ 

Mission statement: create teaching material for FPGAs, processor design and RISC-V, using around $40 per students.

FemtoRV: a minimalistic RISC-V CPU
----------------------------------- 
[FemtoRV](FemtoRV/README.md) is a minimalistic RISC-V design, with
easy-to-read Verilog sources (less than 1000 lines), directly written
from the RISC-V specification. It includes a companion SoC, with
drivers for an UART, a led matrix, a small OLED display, SPI RAM and
SDCard. Its most basic configuration fits on the Lattice IceStick (<
1280 LUTs). It can be used for teaching processor design and RISC-V
programming.


Playing with LiteX: plug-and-play system to assemble SOCs
---------------------------------------------------------
The repository includes [LiteX examples](LiteX/README.md).
The [LiteX](https://github.com/enjoy-digital/litex) framework 
is a well designed and an easy-to-use framework to create SoCs. 
It lets you create a SoC by assembling components (processor, 
SDRAM controller, SDCard controller, USB, ...) in Python.
FemtoRV is directly supported by LiteX (that directly downloads
it from this repository when selected as the SoC's processor). 


Basic: more basic things I wrote during May 2020 - June 2020  
------------------------------------------------------------
Files are [here](https://github.com/BrunoLevy/learn-fpga/tree/master/Basic).
This includes:
- Blinker: the "hello world" program
- LedMatrix: play with a 8x8 let matrix, driven by a MAX7219 IC. 
- OLed: play with a SSD1351 OLed display, driven by a 4-wire SPI protocol.
- Serial: access the included USB-virtual UART pins
- LedTerminal: display scrolling messages on the LED matrix, obtained from the USB virtual UART
- FOMU: simple examples for the "FPGA in a USB dongle", including the FrankenVGA experiment !
- ULX3S HDMI: simple self-contained heavily commented HDMI example.
