Hey everyone, I need some advice. My dad, who's a businessman in the flowmeter industry, thinks the two projects I've been working on for the past 3 months are big steps and that I'm trying to skip some steps. The projects are an ESP mesh for flowmeters and an electromagnetic flowmeter. I agree with him to some extent.

I'll be joining my second year in ECE college in the next few days. What do you think my next step should be? Should I try to get an internship in a business related to IoT (my field of interest), or should I focus on learning more theory? I already have 7+ years of experience with electronics (mainly Arduino, ESP, and Raspberry Pi) and recently finished learning Embedded C. I genuinely need help deciding. I'm really passionate about electronics, especially IoT. Thanks!

Not sure if I'm the right person to answer. But if I have been at your place. I'd have preferred to engage in an internship to gain more technical hands-on experience with professional tools used in embedded & IoT. All this is to be done along with academic studies.

Hi @Event Pings
Last week some of our Engineering Hour attendees experienced technical difficulties with the stream of @Edison's session on DMA so I'm uploading the recording here. As a reminder, here's

Direct Memory Access & How It Will Transform Your Prototype for Production
You’ve heard of direct memory access and know it’s important in certain settings. Now, as your prototype gets closer to becoming a viable product, you need to optimize resources and performance. It’s time to dive head first into the world of DMA.

DMA provides a clear path from peripherals like sensors to memory, circumventing the microcontroller or microprocessor so it can remain dedicated to other tasks. That’s the simplest explanation of DMA, but under the hood there’s a lot more going on.

Tune in as IoT developer and trainer Edison Ngunjiri will walk us through the basics of DMA on an STM32 microcontroller by providing an overview of:

The STM32 DMA architecture
Key components: Channels, Streams, Requests, etc.
DMA Modes of Operation: Normal, Circular

*After providing this background, Edison will perform a step-by-step DMA configuration in the STM32CubeIDE where he’ll set up DMA channels, streams, and integrate peripherals. He’ll then discuss application examples before walking through DMA event and interrupt handling, which he’ll demonstrate during a live memory-to-memory data transfer. *

Don’t miss the chance to learn or brush up on your DMA skills.

I'll also post a link to this in the https://discord.com/channels/1130679493799977062/1212286094830477323 channel chat so you can pose questions to Edison/others about DMA and related topics.

How can we strike a balance between security and performance in IoT devices, especially low-power ones, to ensure robust protection without compromising efficiency, potentially through the use of lightweight encryption and future blockchain-based technologies? @MCU, MPU & Firmware @PCB & Analog

ZacckOsiemo•6/23/24, 4:36 PM

But to what end? how much of your time are you running cryptography when you could be working. Would I use this in antilock brakes? I need security but I need timeliness more.

Ming•6/23/24, 4:43 PM

By doing risk analysis and threat modeling. You would start by looking at the value of the asset you are wanting to protect (hardware, functionality, IP, etc) and then working out the balance from the threats and the cost of protecting them.

For example, I only used AES128 on one of my low powered devices because the data it is protecting only has value for a short period of time, so the lower security is deemed ‘good enough’.

If the data was more valuable, then I would have had to use a more powerful device to enable stronger encryption.

Joseph Ogbonna•6/23/24, 4:49 PM

Oo. What other encryption level is higher than the AES

Ming•6/23/24, 4:56 PM

AES 192 and 256. These have longer keys and more rounds of processing (and therefore takes more computational effort to create).

Hey @here, @Event Pings, the next Engineering Hours is set for a week from today, June 30th, at the normal time of 15:00 GMT.

@Edison will be back to drop some knowledge on clocks and timers as we progress towards task management topics. You can sign up for an event reminder: https://discord.gg/enn7NEdH8w?event=1254450027711954956

FYI, we successfully streamed today on LI and YT so there will be multiple options to tune in on Sunday, but if you want to interact with Edison and the community the best place to join is the Engineering Hour stage here in Discord.

See you Sunday

Of the two I would go for STM32 over ESP if you're considering commercial development. Also, the best way is probably to dive in but course 1 sounds like a good place to start if you need to start at the beginning.

What's the status of the internship you were considering?

For our @PCB & Analog and @Event Pings users, this Friday on Office Hours we're going to be looking at one @hemalchevli's journey into KiCAD development then on to Altium designer, diving into his experience and recommendations for each.
