News
Welcome to the News community!
Rules:
1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source. Clickbait titles may be removed.
Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.
7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

You could run basic brushless motor and BMC firmware on a 99 cent 8 bit Atmel ATMega 328. That code requires almost nothing to run. It's all the extra shit baked in that needs all sorts of processing power.
I also want a basic barebones infotainment-delete vehicle that just has power windows,locks,AC, cruise, and 4x4/awd. I don't want some proprietary gps system or a dashboard where I have to hit 3 menu buttons on a screen I have to look at, just to change a setting (how my wife's car operates and it's a complete shit user experience).
Going a step further, one could, with a bit of difficulty, build the logic out of discrete parts (or packaged ICs) and have it simply work as an electromechanical device. Like things in cars used to.
Complexity and propriety make for good income when it comes to fixing your broken fancy stuff; there's a good incentive to keep it that way. I praise the companies that make long lasting, well designed, and serviceable goods.
So what you're saying is, there's software.
Technically it's not software, it's firmware, because it's a microcontroller that runs code directly.
To my point, you don't need all the fancy bullshit that's baked into the car, the actual control systems require very little compute power.
Firmware is just software. I've done this stuff, it's all just software.
When it comes to writing code, perhaps. But specifically, I disagree on principle. There's a big difference between Firmware embedded directly into ROM that requires nothing beyond the MCU to run, versus Software that requires both a host environment to compute it, host hardware to store and manipulate it, and IO peripherals to make it useful. Totally opposite ends of the OSI model.
All that comes down to abstraction. Lots of stuff has been implemented in bare metal without making the distinction. Every DOS program was almost entirely bare metal except for loading it into memory and some disk I/O.
Firmware is just a subtype of software.
ROM doesn't really exist anymore except on some legacy stuff. Certainly not on the ATmega series you were talking about. At most, these things have fuses that can be intentionally burned out after flashing so they can't be overwitten later.
Huh, That's weird, the last time I checked, the 328P had 1024b of EEPROM.
