The NEORV32 Processor is a customizable microcontroller-like system on chip (SoC) that is based on the RISC-V NEORV32 CPU. The project is intended as auxiliary processor in larger SoC designs or as ready-to-go stand-alone custom / customizable microcontroller.
When I started to dive into the emerging RISC-V ecosystem I felt overwhelmed by the complexity. As a beginner it is hard to get an overview – especially when you want to setup a minimal platform to tinker with: Which core to use? How to get the right toolchain? What features do I need? How does the booting work? How do I create an actual executable? How to get that into the hardware? How to customize things? Where to start???
So this project aims to provides a simple to understand and easy to use yet powerful and flexible platform that targets FPGA and RISC-V beginners as well as advanced users.
The NEORV32 is not based on another RISC-V core. It was build entirely from ground up (just following the official ISA specs) having a different design goal in mind. The project does not intend to replace certain RISC-V cores or just beat existing ones like VexRISC in terms of performance or SERV in terms of size.
The project aims to provide another option in the RISC-V / soft-core design space with a different performance vs. size trade-off and a different focus: embrace concepts like documentation, platform-independence / portability, RISC-V compatibility, customization and ease of use.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
