I would not get into a car implemented with 8051s. I entered the market on a project where an 8051 only had to manage a 2x16 character display, 16-key pad, and several motor/limit switches. The dang thing was challenged at that.
- seanp2k2 5y agoESP32 / STM32 can do a whole heck of a lot, they're getting popular in modular synths now too. AFAIK a lot of vehicles use RTOSes for anything related to driving / vehicle stability, but I think they can use mostly whatever for infotainment, and that "whatever" seems to be largely low / mid-range stuff running absolutely garbage software that only gets updated if NHTSA makes them.
- spacemanmatt 5y agoThat checks out. I've contemplated getting one of those CANbus/ESP32 combos but I'm just not feeling lucky enough to muck around with my car's network for grins.
- 01100011 5y agoSounds like shitty software. We did similar work with an 8051 20+ years ago and it did fine.
- spacemanmatt 5y agoNo, 8051 is just a sloppy piece of silicon. I wrote a symbolic linker and tokenizer for B-52 BASIC and an EPROM formatter so we could cross-develop on PC. We just had a busy little system and 8051 was not very reliable for anything realtime.
