Thanks to @Navadeep we learned that Altium was being acquired by Renesas: general-dev-chat

Then he filled us in with some industry analysis: https://www.linkedin.com/feed/update/urn:li:activity:7164012814137810944?updateEntityUrn=urn%3Ali%3Afs_feedUpdate%3A%28V2%2Curn%3Ali%3Aactivity%3A7164012814137810944%29

Then I saw a post by @ChrisGammell on LinkedIn offering a perspective I hadn't thought of: https://www.linkedin.com/search/results/all/?keywords=chris%20gammel%20altium&origin=GLOBAL_SEARCH_HEADER&sid=.EZ

(Great post, Chris)

Summary is: What do all the other chipmakers think about this? I personally think it's a great move but Chris takes it further explaining the potential to see all the design-ins of competitors over the years. I hinted at this before, but it seems like a good time for some of the big non-Renesas semis to throw some weight into KiCad.

What do our KiCad designers think about this? @JeremyCook @Petr Dvořák @Joseph Ogbonna @PCB & Analog?

Has anyone here integrated machine learning algorithms on microcontrollers for edge AI applications????

Camila_99$$•2/28/24, 1:10 PM

Which microcontrollers and frameworks would you recommend for running lightweight ML models on resource-constrained devices?

JeremyCook•2/28/24, 1:25 PM

Interesting perspective. Being a KiCad user I do like that I don't have to put my designs on the cloud which makes me think of the security of designs I put on Fusion 360 which is pretty cloud heavy. Have not used Altinum or Renesas, but seems the implication is that the designs are largely stored in the cloud there. I suppose what Chris says is conjecture, so I shouldn't jump on companies for the idea that they're getting unfair-ish marketing info, but it does make sense that it would be possible.

In more encouraging thoughts, maybe more companies will throw resources toward KiCad, but I'm not holding my breath either. I've really only used KiCad, so it's entirely possible that other systems are better. I understand Eagle integrates its 3D CAD stuff with Fusion 360, so that is pretty neat, and if it saves designers time a expensive and "cloudy" EDA system could be well worth it.

I'm working on a robotics project and need to select a suitable motor driver for DC motors.

do you have any recommendations for this type of application?

Aaymen ammari do you have any recommendations for this type of application?

Navadeep•2/28/24, 4:10 PM

Quite a broad question. What type is the motor and what's the rating?

take a look at this brushed DC motor controller that comes with I2C interface and some smart features about stall detection(helpful if for a robotic actuator) https://www.ti.com/product/DRV8234

KiCad 8 is out. Went ahead and downloaded/installed it: https://www.kicad.org/ - This video shows some features that may be beneficial: https://www.youtube.com/watch?v=Ohxlmy0p7FE. Haven't done much with it yet myself, but was pretty painless to install on MacOS. Looking forward to getting my hands dirty with it!

8 *Must-Try* features in KiCad 8

KiCad 8 just dropped, and here are Bald Engineer's eight must-try features! The February 2024 release brings a whole host of new stuff to the Schematic editor. However, the PCB editor, CLI, and Simulation tools also received attention. (There are something like 900 closed issues for the 8.0.0 Milestone!) Which of these is your favorite?

Petr Dvořák•2/29/24, 9:00 AM

Unfortunately, the lead SW engineer of the KiCAD v8 is probably a big mouse fan. Many features changed from pure keyboard-wise to a clicking hell. Even the route command in the PCB editor needs to be invoked by the X key and confirmed with the left mouse click. This is the highest possible stupidity and the efficiency killer. The new BOM tool is a chapter of its own.

Petr Dvořák•2/29/24, 9:03 AM

I was surprised by how many influencers glorified the KiCAD v8 on the day of the release. Everything needs time for testing and verification. We are still in the beta phase with the KiCAD v8, even though they say it is the official release.

Petr Dvořák•2/29/24, 11:43 AM

You need to check the Reference manual of your chip for the memory architecture. There is no general answer. There can be differences, especially between "normal" and "special" devices (Critical safety, etc.). Generally speaking, no. Each device has privileged access.

Petr Dvořák•2/29/24, 12:03 PM

You said, "at the same time". Of course, you can access the memory from two peripherals. You need to implement a circular buffer or similar memory structure. Ask @Umesh Lokhande or others for the best implementation practices. The HW side is safe here.
