Navadeep•2/28/24, 4:46 PM

Yes, PWM is the control mode for DRV8234.

aymen ammariOP•2/28/24, 4:48 PM

Very good!! That suits me well, I'll give it a try

How do I choose an RTOS for my project?

Hello, i wanna do hand gesture recognition with my robot camera , but the thing here it's only using python 2.7 , is there is any libraries for recognition suitable with that version of python!?

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.

Oonky @Petr Dvořák Do you have IPC CID/CID+ certification?

Petr Dvořák•2/29/24, 9:03 AM

No, I don't. Do you?

youcef_ali•2/29/24, 11:27 AM

in cpu/mpu architecture the memory can be used by two peripherals in the same time, one for reading and writing in the same time ?

PPetr Dvořák No, I don't. Do you?

onky•2/29/24, 11:33 AM

No, I don't have it either.
I wanted expert opinion if it is worth getting one, what to expect and towards whom it is targeted.

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.
