"Helping companies to discover their IoT needs" is often the statement I hear. The reality is that companies do not have "IoT needs"; they have business needs that can be fulfilled by utilizing IoT technology.

Yes, this is a good observation. That nuance is often lost until people find themselves with a pile of tech and a pile of bills and no revenue haha

@LMtx are you going to be at Embedded World or Mobile World Congress? You should go to IoT Stars. Same for you @InsightMike if you're going to be at either of those shows.

Joseph Ogbonna•2/21/24, 6:21 PM

Microcontroller are for low end embedded applications that don't require much computation. Used in most IoT devices. They have lesser memory that microprocessor, usually in the range of KB and MB. While microprocessor can be used in high end applications like computer boards. Though they have much differences

Hello everyone I'm a biomedical engineering trying to get into the entrepreneur world.
My main goal for now is to get the most power out of the esp s3. I'm reading some books, forums and groups about the best IDE.

For now I'm between esp IDF and platform IO I'm looking for something in the middle between practicallity and capabilities

techielew•2/21/24, 9:41 PM

Platform IO is going to give you breadth of hardware support if you plan on moving beyond ESP in the future. Another option might be Embeetle, which @kmulier developed. However, you might want to get feedback from @Umesh Lokhande @Aditya thakekar @Joseph Ogbonna and others who actively develop on ESP to get their take.

kristof-at-embeetle•2/21/24, 9:43 PM

Hi, Embeetle IDE here.
@yepeto99 : Embeetle doesn't support the ESP32 microcontrollers yet. We will add them in the future though.

Open source documentation is extensive on esp32... Try merging esp-idf with tensorflow lite.. AI dataset modelling just skyrockets the applications.

Petr Dvořák•2/22/24, 6:01 AM

Thank you for your activity, @kmulier. When adding a new symbol, I prefer keeping the designator with the ? wildcard. Then, after all changes are implemented, the annotation of the entire schematic is done. Or sheet by sheet. Or selected block by selected block. It all depends on the project. Some customers wants different series for different sheets or blocks. If the new kicad_designators plugin works for you well, I am happy!

Navadeep•2/22/24, 7:10 AM

are you on MSP430FR seires?
I agree with the tediousness coming to MSP libraries and APIs. Not quite intuitive as ST or Renesas. Nordic nRF54 series and SiLabs C8051F have pioneered low power one with radio and other for low-end processing.
During college, I learnt assembly on one of these MSP430FR5994 launchpads from this Prof's YouTube https://www.montana.edu/blameres/

I have worked on Infineon series of parts and seen their Capsense which is ultimate. Note that it is MCU integrated in their PSoC series of chips and provides and GUI to configure sensitivity, pattern etc. If you're looking for external IC, check https://www.ti.com/product/FDC2214
opens up quite interesting applications.

In a separate but related note, I've just published the meeting thread for this week's Office Hours, which will focus on migrating from maker to professional development platforms and practices, notably for those who started on Arduino: https://discord.com/channels/1130679493799977062/1210162122332442645

Once Arduino started introducing Arm-based devices, ST may have been the closest commercial-grade solution.
