Mine, easily. Senior (near staff) level embedded engineering.

It will spin up a boilerplate uboot or BSP config no problem. I still go in and manually check and add peripherals, but opus 4.7 is terrifyingly smart.

Need to modify or add a new peripheral, it's there no problem. Or in a bare metal project, I can point it at an STM32 cubemx starter repo and ask for a feature (set up the ADC on pins 4 and 7, ask me for parameters) and it's just done. I do in a day what would probably take me 2.

It doesn't help me with reviewing others' work, or planning (I maintain that these are manual tasks). So yeah, I agree with the 40-60%. The parts of my job it helps, it really helps.

My experience is it will attempt read from the wrong memory block resulting in garbadge. But that's a while ago so maybe LLMs have gotten better.

The AI labs have all released at least 3 new models each since december, things move very quickly.

Yeah, the industry has no issues selling $5 bills for $1. Why is this a good thing for society again? That the public subsidizes VC to no shared gains?

I've been hearing "the new model is so much better than the one from 6 months ago" every few months since 2023. It's never been true to date, so please understand why I am skeptical that it suddenly became true this time.

Yeah just had Codex/Gemini write me nrf52 bootloader that fit in under 4k flash sector size with OTA and DFU support (well, app does OTA download then the bootloader validates and decompresses the image). Works best if you let them use OpenOCD on a real device, then they can iterate until it starts working.

I didn't even need that bootloader, just didn't like the fact that Adafruit one takes too much space :)

I'm confused, isn't the whole point of using the STM32CubeIDE that all the peripherals, like say setting up an ADC on pins 4 and 7, are checkbox features?

Yes but it's famously clunky, and if I'm already in an existing repo, a prompt will do it much, much faster.

It also generates a ton of bloat and comments.
