OnChip Open-V Arduino Compatibility

OnChip has posted a Crowd Supply update on their plans for Arduino compatibility:

Open-V Arduino Compatibility

Arduino compatibility can mean a lot of things to a lot of different people, so we’ll try to be as concrete and specific as possible. For the Open-V, Arduino development tools, and interoperating on a hardware level with existing Arduino shields.

We’ve updated our live, web-streamed demos to include an Arduino mode in addition to the assembler and C modes we already have. You might also notice the relatively new Blockly modes and a refined layout of the demo page. Go write some code and see the results live streamed!

Bristlebot with LDRs Becomes Light-Following Bristlebot

Bristlebot with LDRs Becomes Light-Following Bristlebot

Bristlebots are great because no coding is required – they’re completely analog circuits that just go! But if you wanted them to go in a specific direction, how would you do that? Facelesstech has released their design for a light-following bristlebot that uses two LDRs to drive either side of the bristlebot (so you could turn it, somewhat – see video below for demo!). It’s pretty simple and pretty clever.

$3 Tinusaur board on IndieGoGo

Neven Boyanov has launched a new Tinusaur campaign on IndieGoGo:

Learn, Teach and Make with the Tinusaur

Small microcontroller board that could run Arduino and help you learn, teach others and make things

uvloj5csuhcx0ri4yn5c

The Tinusaur is powered by the Atmel ATtiny85 microcontroller.

We want to bring the cost down to $3 for the basic “lite” boards
and allow more people to be able to get them.

IceZero FPGA Board for Raspberry Pi

Black Mesa Labs created this board that adds a Lattice FPGA to a Raspberry Pi:

ice_zero_with_pi_zero

IceZero FPGA Board for RaspPi

BML has been very much enchanted with the Lattice FPGA boards for Raspberry Pi, IcoBoard , BlackIce and IceHat. The IceZero board is a BML creation that attempts to combine the best features of all 3 boards into a single design.

IceZero features common with other designs

  • Fully Open-Source Hardware and Software Design.
  • Lattice ICE40HX4K FPGA that supports Clifford Wolf’s Project IceStorm tool chain.
  • Interfaces to Raspberry Pi 2×20 GPIO Header for both power and bus interfaces.
  • PROM programmable directly from Rasp Pi, no JTAG programmer required.
  • External SRAM, supporting soft CPU core designs ( code execution ).
  • Extra large SPI PROM, supporting soft CPU core designs ( code storage ).
  • Industry standard PMOD expansion headers

IceZero features that are BML specific

  • Mesa Bus Protocol 32 MHz SPI link between CPU and FPGA.
  • 2-Layer PCB design. Orderable via OSH-Park or Gerbers for Downloading.
  • FTDI 1×6 USB Serial Cable header for use with PC instead of Pi ( or as a soft CPU debug Trace Port ).
  • Single Pi UART plumbed to FPGA for muxing to multiple external serial devices.

BlackMesaLabs has shared the board on OSH Park:
