Re: Nissan on Frankenso #47

this looks like your contrast level is too high. i had a similar problem in a different setup. if I recall it correctly, you need to play with voltage on the contrast pin of that lcd module (v0) - is it also connected to frankenso?

Re: Wideband Controller: Fully Custom, no ASIC!

I thought that GD was a full-cycle manufacturer. Do they source wafers from some other companies? People say, this crisis will last for at least a year. Changing a package in the PCB probably takes a few hours. If you are switching to a different package within the same MCU, probably there won't be ...

Re: Wideband Controller: Fully Custom, no ASIC!

considering this ongoing crisis, why not GD32?
GD32F190 is a 5-V series.

Re: Hellen 72 - Miata NB2 up to 8 cylinders

Will it be just one WBO (considering initial notion of 8 cylinders, which probably implies two banks of cylinders, hence, two WBO sensors)?

Где-то попадался аппноут про то, какой размер должен быть у зуба относительно сердечника датчика. Я бы смотрел сигнал осциллографом, прежде, чем делать выводы. Ну и попробовал бы повернуть датчик по оси.

Just a thought: with all these wireless connectivity options, security becomes sort of a concern. I'd suggest to implement a 'read-only' mode for such communications, to be enabled/disabled either with a physical jumper or a password-protected checkbox.

Nice! Couple of dozen components are on the other side of the board - probably need to be soldered manually, but that's okay.
