I2C is a bit goofy though. As a byproduct of being an undiscoverable bus you basically just have to poke random addresses and guess what you’re talking to. The fact lmsensors i2c detection works as well as it does is a miracle. (Plus you get the neat issue where even the act of scanning the bus can accidentally reconfigure endpoints)
Yeah, the lack of proper discoverability on i2c truly sucks. You have to just poke random addresses and hope for the best to see if an i2c device exists on the bus. It’s a great standard but I wish it would get updated with some sort of plug and play autodetection feature. Standardized device PID/VID system like USB and PCI would be acceptable or a standardized register that returns a part string. Anything other than blindly poking registers and hoping you’re not accidentally overvolting the CPU or whatever because the register on your expected device overlaps with the overvolt the CPU register on the same address of a different device.
I’m curious. There was some i2c connected memory devices before. Is there some forgotten spec that allows for a flexible device lookup / logging capability. Something that acts like device tree but stays specific to the bus. It wouldn’t be practical for a lot of applications but I could see it being useful for some niche stuff.
