Introduction to Real-Time Linux: Unleashing Deterministic Computing

In 22.04, Canonical announced a beta version of the Ubuntu kernel with the PREEMPT_RT patchset integrated. The new real-time kernel serves extreme latency-dependent use cases and provides deterministic response times to service events. By meeting stringent preemption specifications, real-time is suitable across a broad range of verticals, from t...

Yes thanks, I tried it out

RémiOP•4/18/24, 3:53 AM

Your welcome

RémiOP•4/18/24, 3:54 AM

Maybe you can try to do it and come back with more precise questions or errors

RémiOP•4/18/24, 3:54 AM

The little I know it's "only" a patch

RémiOP•4/18/24, 3:56 AM

It seems you can activate this in the Linux kernel build options (I'm not sure about it)

Hello guys, TIP112 transistor, if we replace it with TIP122, it wouldn't be a problem, right?

aymen ammari•4/18/24, 8:12 AM

Replacing a TIP112 transistor with a TIP122 transistor should generally be fine, as they are both Darlington transistors with similar characteristics. However, it's always a good idea to double-check the datasheets and ensure that the TIP122 can handle the required voltage, current, and power ratings of your circuit.

Are you a developer looking for work? The deep tech job market has been tough for months.

In this week's Office Hours meetup, @Marcweb from tech recruiting firm Webster & Webster will join us to go over resume/CV and job application best practices. We're looking for a volunteer to submit their resume so we can review and upgrade it live during the session.

DM me, reply to this message, or post your resume/CV in the #jobs channel for consideration.

Otherwise we'll see you in this week's Office Hours Meetup on Friday at 15:00 GMT:

wafa_ath•4/18/24, 3:17 PM

the main difference between the TIP112 and TIP122 transistors is the maximum collector current . The TIP122 can handle higher current loads (up to 5A), while the TIP112 is limited to 2A. So i think it fine to replace it ...

Go through the component datasheet thoroughly mostly on the package part. And make sure your pin naming is correct to avoid mistakes, later in your design

Yes, but… idk if it’s been proven in anything other than the STM32F7 board mentioned. Article says there is a lot of interest/requests for OpenCV on micros but this appears to be a GSoC project that hasn’t been touched in a while.

I agree. Perhaps some STM32Mx that can run Linux can also qualify for the OpenCV. That should decide some embedded FW jockey.
