Hello everyone,

Recently i am working on a project in which i have to convert my developed device with IoT so i have little bit confusion that which one best to use so I want opinion from Element14 Community members.

Which one have to use GPRS module or XBee module to convert developed device with IoT?

Which manufacturer's Microcontroller do you prefer or trust for your " low power design applications "

I am currently designing with Texas Instruments microcontrollers and I trust them for low power applications specifically for those applications running on batteries. I think their ultra low power microcontrollers with Code composer studio which has in-built ULP advisory(not to mention GRACE too) is best for creating power controlled products. By this poll I want too know what you guys choose or prefer for low power designs? or Am I missing something already which I should have considered for power specific products? Please give your suggestions too.

Where do you go for embedded solutions, integrated modules?

Google is the first place i go. For example if i need a echo cancellation module, i would go google it.

Where do you go?

Any specific sites?

What is the most effective form of Technical Training for professional engineers?

Former Member — Mon, 11 Oct 2021 15:01:21 GMT

Some colleagues and I were discussing the most effective form of Technical Training for professional engineers.

When discussing the different training methods, we were considering different trade offs like time taken, cost, benefit, etc. We've come up with this list and we each have our preference.

We'd like to increase the sample size and see what other people think.

The Systems and Software Engineering Process

DAB — Mon, 11 Oct 2021 15:01:06 GMT

I have noticed that many of you are not sure of the right procedures to use for developing a project successfully.

I am prepared to create a simple Process for the E14 community if there is enough interest, so I need you to tell me if I should spend the time to build the process and training workbooks associated with the process.

So let me know if you are interested in seeing what a formal process looks like to take your tinkering to a new level.

Thanks

DAB

Small form-factor microcontroller board families

wolfgangfriedrich — Mon, 11 Oct 2021 14:59:56 GMT

Current Revision posted to Polls by wolfgangfriedrich on 10/11/2021 2:59:56 PM

Which of the following board types / eco-systems do you think has the largest exposure and has been used in real projects the most?

This is about form factors smaller than the standard Arduino Uno format. I am thinking about new shields and want to put a second connector option on there to make it more flexible. It is going to be a display function, so I am not really interested in the higher power computer modules like RaspberryPi and such which already have video output.

Breakout board for a BGA chip

wolfgangfriedrich — Mon, 11 Oct 2021 14:58:54 GMT

Current Revision posted to Polls by wolfgangfriedrich on 10/11/2021 2:58:54 PM

printf(F("Hello World!));

I am planning a breakout board for an BGA chip and have so many decisions, that I would like to get some input from the community.

The BGA is a 5mm x 5mm 24-ball BGA (pin A1 is missing). The device is the VLSI VS23S040 Composite Video/RGB/VGA + Memory controller.

To make the part usable I would add the crystal and bypass capacitor to the breakout board.

Some options that make sense to me are:

2.54mm (0.1") pitch, pins on 4 sides: 18mm x 18mm size, easy to handle and solder, not so easy to test. Not testable with horizontal pogo pins.
2.54mm (0.1") pitch, pins only on 2 opposite sides: 32mm x 10mm size, to be usable on a prototype board, the pins could only be on 2 sides. This would make the board unnecessary big, but more versatile.
2mm (80mil) pitch, pins on 4 sides: 14mm x 14mm size, would give the smallest area footprint and be still easy to solder. Not testable with horizontal pogo pins.
1.27mm (50mil) pitch, pins on 4 sides: 9mm x 9mm size, BGA only without crystal. Smallest size ever.
1.27mm pitch, pins on 2 sides: 16mm x 8mm size, very small with crystal and testable with pogo pins.

Ideas for any other configurations. Please tell me in the comments

Thanks for having an opinion.

- W.

PS: I was hoping the image are comparable scale, but they are not.

Favorite microcontroller language?

neuromodulator — Mon, 11 Oct 2021 14:58:33 GMT

Current Revision posted to Polls by neuromodulator on 10/11/2021 2:58:33 PM

I like C++ a lot, specifically I love OOP and the STL. If I had to write everything in plain C I would end up writing a lot of boilerplate code ('\0' supporting strings structures and functions; and container-alike structures and functions), time I would rather like to spend on the system functionality. Still, C++ is not well supported on microcontroller, as plain C has been the defacto for a long time.

What is your favourite language when programming microcontrollers and why?

Will Edge Computing Transform IoT as Cloud Computing Transformed Enterprise IT?

rscasny — Mon, 11 Oct 2021 14:58:31 GMT

Current Revision posted to Polls by rscasny on 10/11/2021 2:58:31 PM

Edge computing works by selectively moving cloud-compute processing from cloud data centers to edge and end node processing platforms. Edge computing also helps to guarantee user’s privacy and security by sanitizing traffic to the Cloud, filtering personally identifiable information where necessary.

Edge computing systems often operate over public networks, consequently they require integration of both wired and wireless network connectivity and importantly, they require being built with a hardware root of trust. Hardware root of trust is an approach to computing where the processing of security algorithms as well as key and certificate storage are performed in trusted hardware. Hardware-based trust systems are much more robust than software-based systems against cyber-attacks seeking to compromise software-based systems.

So, what do you think: Will Edge Computing Transform IoT as Cloud Computing Transformed Enterprise IT?

(If you aren't sure, then please join me as I host our first (of many) edge computing webinars: IoT Webinar: Computing at the Edge - When, Why and How )
