A designer has made use of the camera on a Raspberry Pi computer module to create an internet-connected photo booth which can link to a smartphone. Flask, the webserver module is combined with Flask-Socketio to provide a web interface and controller that accesses the Raspberry Pi camera. Using the GPIO pins to control a relay module hooked up to two strip ...

EnSilica goes multi-core for comms stacks

EnSilica eSi-RISC

EnSilica has launched an asymmetric multicore processor for executing wireless communication stacks. Called eSI-32x0MP, in dual-core configuration “One processor is optimised for implementing physical [PHY] layer processing and the second core is optimised for running an advanced protocol stack,” said EnSilica. “The eSi-32x0MP is ideal for implementing low-power Wi-Fi and wireless/cellular IoT standards such as LTE Cat-0,” said EnSilica CEO ...

ARM tools reduce design months to days

ARM Socrates IP tooling

ARM’s has come up with a tooling suite which claims to enable SoC designers to configure, create and assemble IP-based systems over the course of days rather than months. The suite comprises Socrates DE, CoreSight Creator and CoreLink Creator. Additionally, CoreLink Creator will configure and help implement the CoreLink NIC-450 Network Interconnect, the follow-on to CoreLink NIC-400. The new suite ...

Raspberry Pi meets IoT with solar powered camera

FW3S1DFI92LXF04.MEDIUM-300x200.jpg

This design of a wireless camera module works on ‘its own’ power without being connected to the electricity mains. Based on a Raspberry Pi, it is a solar-powered radio beacon which transmits signals in regular intervals including live images taken by a small camera. Since the device will transmit using a simple radio, no wired or cellular coverage is needed, ...
