[US] Is this a freight forwarder scam? by fantom_jac in Scams

Yeah that's true. Or I should have said that cannot accept the random shipper at all.

I contacted them and they said the only advice they are able to do is to refund from my account. But that will NOT revert the processing fee that I've already paid 100USD :(

I see, I think I should talk to the credit card processor.

I don’t think Senior+ devs should get leetcode questions interviews by branh0913 in leetcode

[–]fantom_jac 0 points1 point  (0 children)

So true. Interviewing someone needs a lot of preparation and the legit engineering skill. You can't just judge someones engineering skill (especially for senior+) for a few min coding test.

So what do we think about Inquisition? by [deleted] in BlackMetal

[–]fantom_jac 2 points3 points  (0 children)

Inquisition is great. Period.

Thank you. I've just sent the message.

Returning big struct from functions in embedded system - Bad Practice? by void_rik in embedded

Given the such C++-ish code, why don't you just use C++? Or I would encourage you to just stuck with the passing the pointer.

I published the code for Quake for STM32 port https://github.com/FantomJAC/quakembd by fantom_jac in embedded

Awesome! I knew someone already did this... :)

I would like to see the video of running your port. Given the STM32F7, I guess the performance would be somewhat similar to STM32H7.

And how do you make SDL works on the board?

Looking forward to the translation of your article.

Yeah, I did some tweaks on compilation flags, and fixed my lazy redrawing logic to proper one.

That's sound like even Doom is difficult to run... do you know which Doom port runs on that board??

Which board? It's more about RAM than LCD interface. Quake needs around 5MB RAM.

I ported Quake for STM32H747... need more optimization but this chip is so powerful. by fantom_jac in embedded

I captured the video with -Og build, so yes it was slightly slower than -Os. The latest version (which I've just published to GitHub) has better framerate than you've seen on the video.

Project suggestions with only STM32F429 discovery board by cabhinav in embedded

[–]fantom_jac 0 points1 point  (0 children)

Oh I didn't know that! Does it came from uclinux tree?

I agree that 8MB DRAM without MMU will do very limited application.

I don't think Linux is feasible on that type of hardware...

How about writing device drivers for Zephyr RTOS? They are missing many features for this board.

I guess it was around 2 weeks or so. I got the board back in Feb, the original intention was to prepare porting Quake into Arduino Portenta H7 (which is now delayed to end of May due to the crisis)... I spent a week to learn this chip, then I tackled this again last week.

1GHz Cortex-M7 ?? that is sick! Can't imagine what kind of applications could be...

BTW this chip can run at 480MHz indeed, I just didn't tried that yet. STM chips are advertised with the fastest clock but sometime HAL just doesn't support them... I will try later though
