Developed in a magic night of 19 Aug, 2018 between 2am and 8am, the darkriscv is a very experimental implementation of the open source RISC-V instruction set. Nowadays, after one week of exciting sleepless nights of work (which explains the lots of typos you will found ahead), the darkriscv reached a very good quality result, in a way that the “hello world” compiled by the standard riscv-elf-gcc is working fine!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

check out my implementation of the RISC-V architecture. I worked on a fully compatible RV32I core since 2015 and it works (and can be easily ported to) on several FPGAs. Example software included, simulators, libraries and even a RTOS. A version of this core was fabricated and validated in silicon (TSMC 180nm). https://github.com/sjohann81/hf-risc
