Display Serial Data on a Web Page – Using PHP or Python Scripts

Occasionally it may be useful to visualize a continuous stream of data arriving through a serial connection as a web page in a browser. But how do you go about? May we suggest a bit of scripting?

Dragino is a manufacturer of IoT hardware, specialised in Linux IoT/VOIP, Arduino Yùn add-on boards and LoRa modules and gateways. One of their latest products is the LSN50 long-range LoRa sensor node, designed for outdoor use.

A Raspberry Pi plus a homebrew HAT with driver software and a custom graphical user interface created especially for this application combine to make a unique FM radio that is not only eye-catching but a fascinating learning experience, thanks to extensively detailed documentation. Nobody can fail to learn something new from this wide-ranging project!

New from Octavo Systems is their OSD335x C-SiP incorporating an ARM Cortex-A8 Sitara AM335x processor from Texas Instruments. The main features are: ARM Cortex-A8 processor, up to 1 Gbyte of DDR3 RAM, 4 Kbyte of EEPROM, two power supplies, up to 16 Gbyte of eMMC flash, MEMS clock oscillator, over 100 passive components on 400-ball BGA.

Linux will always face a challenge. However, the emergence of many ‘minicomputers’ such as the Raspberry Pi (and variants), the Beagle Bone, the DragonBoard and the Odroid, which all use a Linux operating system, has given a healthy boost to the number of Linux users. If you haven't joined them yet, here is an interesting and simple application to get your teeth into: hangman.

The 4th generation of miniature fanless PCs from Compulab and the folk behind Linux Mint is... (drumroll) MintBox Mini 2 (MBM2)! Processing power comes from a quad-core Apollo Lake Celeron J3455, and MBM2 is supplied with the Mint 19 ‘Tara’ Cinnamon installed.

In his article Automation Meets IT with CDP Studio, Odd Gilinsky of CDP Technologies provides an easy introduction to building fast, distributed control systems on industrial computers. The article was previously published in Elektor Business Edition issue 2/2018, and is now offered as a free download to all Elektor e-zine readers.

Wheezy, Jessie, Stretch? Huh? Pi OS’s form a complex landscape where many newcomers to this fantastic little computer may get lost, unable to see the wood for te trees. Relief has come. Released by Eltechs and freely downloadable (what did you think!), the Ultimate Guide to Raspbian and other Raspberry Pi Software is modestly presented as a “blog post”. It’s a true guide though and sure to contain information which will be interesting for both starters and seasoned Raspberry Pi (or other ARM and IoT) users, owners, developers, and even investors.

Acquisitions and innovation abound in the electronics industry. As a result, the industry is evolving each month. Let’s review some of the most important electronics industry news stories from the past several days.

With Arduino Create, the online integrated development environment (IDE) for Arduino the user now gets direct access to popular Linux boards like the Raspberry Pi, BeagleBone and AAEON UP² as if they were Arduino boards.
