Pipistrello: A Papilio format “Uber Board” with HDMI and BGA.
Papilio user Magnusk made a very interesting FPGA board that he calls Pipistrello, in the past he used some different papilio boards and he like them but he wanted a board with HDMI interface, lots of RAM for buffering, high-speed USB for data streaming and SD-card for data storage. So the only option left was to make…

SoundPuddle: Help Support a Papilio based Art Installation on Kickstarter.
John English, of Boulder Engineering Studio, has put together an amazing art installation the uses a Papilio to drive 1664 RGB LED’s! The SoundPuddle uses the ZPUino Soft Processor to implement 16 SPI masters, a 1024 point FFT, and a VGA like framebuffer interface to drive it all from a sketch! An ADC connected to…

Quadrature encoders on the ZPUino.
Papilio user IvanJH made a “simple” quadrature interface for the ZPU, using the standard HD44780 code in the ZPUino IDE install, and a sketch to read the quad counter and write to the LCD. I created my own “simple” quadrature interface for the ZPU, and using the standard HD44780 code in the ZPUino IDE install,…

AltOR32 OpenRISC ISA CPU on The Papilio One 250K
Ultra-Embedded is at it again! this time with an OpenRISC CPU. After managing to run a ‘MPX’ soft-core processor on a Papilio One 250K board he have developed another soft-CPU project for this low-cost FPGA development board. AltOR32 is an OpenRISC 1000 architecture derived RISC CPU targeted at small FPGAs and contains only the most basic ISA features from the OpenRisc project and it should run…
