Ardunio IDE 2.0 is finally here with new features and enhanced UI

Posted on 25 October, 2022 by Rakesh Kumar, Ph.D.

The beta version of Arduino IDE 2.0 was released in 2021 and is now available to download in its stable version. Various feedback and input from multiple stakeholders of the Arduino Community have enabled the makers to launch the stable version. The backbone of Arduino IDE 2.0 is the open-source project Eclipse Theia Framework.

This blog article will take you through the various features of the Arduino 2.0 IDE.

Sketchbook: The sketchbook allows you to access the .ino files directly with a few clicks. The folder icon on the sidebar allows for this.
Boards Manager: This new IDE offers straightforward access to the board manager on the front end of the IDE itself. In the earlier version, a user had to go all the way to settings and enable the board.
Library Manager: Libraries often include many third-party extensions, making life easier working with Arduino. As this feature is often used, it is a good idea to make it into the sidebar of the IDE.
Debugger: This is a new and much-needed feature for the Arduino community. Especially for beginners who are lost in the maze of coding and unable to figure out where their potential flaws are lying hidden, this feature offers much breathing space.
Search: The last of the tools in the sidebar is the simple yet powerful “Search.” One can use this feature to find any snippets of the coding.
Serial Monitor: Remember using a separate window while trying to open Serial Monitor? Now the Serial Monitor is integrated with the IDE at the bottom. This offers the IDE and the Serial Monitor a compact look.
Serial Plotter: With the help of Serial Plotter, it is easy to visualize data in graphs. In their visual form, the graphs offer many insights into the data and derive meaningful conclusions from it.
Autocompletion: This is a feature that I like, which allows for faster coding typing. What it does is that it suggests all the possible variables and functions while one is typing them. This also allows for fewer typos in the code which is quite common for a beginner and often annoying.
Themes: Needless to say, the themes play a prominent role in user experience, and the new editor has ensured that Arduino IDE 2.0 offers a range of themes, including the often-used Dark Mode.

Overall, this improved editor has a responsive interface that offers the programmer a better user interface. The compilation time has also been reworked to make it faster than its older counterpart. Another good thing about this new version is that it can update on its own without the need for manually downloading the more recent version and installing them. So hassle-free updates!

ODROID H3 and H3+ Boards Come with Intel Jasper Lake Quad-Core Processors

Posted on 25 October, 2022 by Emmanuel Odunlade

Last year, when Hardkernel decided to discontinue the production of the ODROID-H2+ SBC as a result of the global chip shortage currently faced by the IoT market, we thought that was the end for that line of boards, little did we know that the company had a lot up their sleeves.

We are pleased to inform you that Hardkernel has now brought back the ODROID H-series with not just one, but two new single-board computers based on 10nm Intel Jasper Lake quad-core CPUs: the ODROID-H3 and ODROID-H3+ SBCs.

The ODROID-H3 is powered by a 2.9 GHz Intel Celeron N5105 quad-core processor with 24EU Intel UHD graphics @ up to 800 MHz while the ODROID H3+ is based on a 3.3 GHz Pentium N6005 quad-core processor with 32EU Intel UHD graphics @ 900 MHz. All other features seem to be the same for the two; they both support up to 64GB RAM, have the same M.2 PCIe Gen 3 socket, and the same 2x 2.5 GbE, 2x SATA ports, 2x USB 3.0 and 2x USB 2.0.

Specifications of the ODROID H3/H3+ Include:

Adafruit Redesigns the INA219 Power-Monitoring FeatherWing Due to Component Shortages

Posted on 20 October, 202220 October, 2022 by Emmanuel Odunlade

It’s been well over a year now that the IoT market has been battling against the ongoing industry-wide component shortages and this has no doubt caused huge financial losses for companies served by these chips. While this global crisis continues to linger on with no certainty as to when it is likely to end, electronic industries are beginning to find ways to bring relief to their operations.

Adafruit has now updated its INA219 FeatherWing designed for power monitoring applications, retaining all the features of the original design but giving it an accuracy that will now vary depending precisely on the parts the company can get its hands on at the time.

“Due to the severe chip shortage, we have had to update this design to use either the INA219A or INA219B and in SOT-23 or SOIC package – whether we are able to get on the market!,” Adafruit writes.

The Adafruit INA219 FeatherWing was designed to solve issues around power monitoring, adding accurate power monitoring to Feather-format projects.

“Instead of struggling with two multimeters,” the company says, “you can just use the handy INA219 chip on this breakout to measure both the high side voltage and DC current draw over I2C with 1 percent precision.” The INA219 FeatherWing is built around Texas Instrument’s INA219 current shunt and power monitoring chip and can work with any and all Feathers including the new Particle Argon, Boron, and Xenon.

The INA219 FeatherWing is super simple to use. It communicates over I2C and it is still possible to change the I2C address to have up to 4 of the Wings on one Feather. The INA219 is smarter than most of the average current-measuring devices which are only good for low-side measuring. For many of them, you may have to stick the measurement resistor between the target ground and true ground, and this can in turn cause problems with circuits as electronics do not like it when ground references change and move with varying current draw. The INA219 however is powered with 3.3V and can handle high-side current measuring up to +26VDC.

Thankfully, the new design did not bring any changes to the device’s operation, so projects and software built around the original design can use any variant of the new design without change. Speaking on the variants of the new design, Adafruit said that

“the A version is ±1 percent total max current measurement error over the entire temp range (±0.5 percent max at 25°C [77°F]) and the B version is ±0.5 percent total max current measurement error over the entire temp range (±0.3 percent max at 25°C [77°F]). Overall functionality is otherwise the same.”

The new design of the INA219 FeatherWing still measures the same 51mm by 22.8mm by 3.6 mm and weighs 3.4g. It is now available in the company’s store for $7.95 with a discount that applies if you are buying more than 10.
