saw this in my feed that an old 80s car had a crt touch screen. now i wanna make suzui-rs be like this.

time to go embedded and a separate screen and what not

ironic I'd make it in rust, and most of these cars would also have.. a different kind of rust

why do i get into things that make me go mad

small progress each time though. so maybe worth it

I can't solder. fine. but the cycle of updating code, flash it (disconnect esp8266 cuz I'm using hardware uart which usb also uses, then reconnect).

being a newb doesn't help. let's see where this goes

doing an "actual" embedded project now (automotive).

Using esp-idf framework. Writing (learning) in C.

Tried rust bindings but maybe skill-issue that I got a lot friction trying to make it work with bluetooth classic

finally settled on a layout and feature list.

Only thing left are:
- stabilize fuel consumption error rate
- DTC support (history + current)

other than that, this project is complete.

after a couple of corrections, my car scanner now reports ~+4% fuel use than actual.

Not having to rely on estimating fuel gauge is really helpful.

fuel consumption data added to my project. Not too accurate but it's still marked unstable

- fuel (instant consumption, total used, fuel consumption in L/100km)
- distance travelled

next up:
- DTCs
- context aware load gauge (red when lugging, or flashing)
- smol speaker for (above, overheat etc)
