Internet of Things (IoT) manufacturer Ciseco has released the 'Pi-Lite' LED display for the Raspberry Pi. The bright
LED matrix has an on-board processor, allowing Raspberry Pi users to
display messages and graphics by sending simple commands and text
strings to the serial port.
The ‘Pi-Lite’ display unit is a pre-built plug & play module, but it
can also operate in stand-alone mode, and when combined with one of
Ciseco’s radio modules can even form a wireless
display unit. The ‘Pi-Lite’ idea comes from the very popular Arduino
Lots of LEDs shield by Jimmy Rodgers and brings these capabilities to
the Raspberry Pi user. The board features a 9x14 (126) red LED matrix (a
white version will be available soon), an on-board Arduino ATmega 328
processor allowing each pixel to be individually addressed, and an
on-board controller that can be upgraded or reprogrammed using the
standard OptiBoot serial bootloader. The kit comes with Ciseco firmware
that will scroll text, display bar graphs, VU meter, and address
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
