I would not wash the food, only the dishes. My opinion. :lol:

"The starter motor plunger closes..." I doubt it can according to the schematic!

Re: Arduino based 7 solenoid TCU

Very interesting. I'd like to learn how these ZF 6HP and 8HP can be driven with custom hardware.

Re: VR emulator

Could not use a sound card and a power amplifier or a transformer for the voltage swing?

Re: SIMPLE RPM detector Arduino and Knock Sensor

I assume that the knock sensor works as a kind of microphone and delivers an analog signal.
If so, amplifying, digitizing and then applying a FFT would give the fundamental frequency of that signal that, I think, should be related to the RPM you're looking for.

Re: hip9011 integration

According to the STM32F411xC/E datasheets (RM0383, DM00115249), PA8 can be configured as alternate function MCO_1 (Microcontroller Clock Output) and PC9 can be configured as alternate function MCO_2. * MCO_1 can be generated from HSI, LSE, HSE, PLL through a 1 to 5 prescaler; * MCO_2 can be generate...

Re: Hello from France - Project for an old british car and my own approach to HAL

That car is fantastic. It'd be a shame if you ruined it with rusEfi... :P I've seen some pretty convincing fake Weber DCOE carbs that covertly contain a pair of fuel injectors... I think Jenvey in the UK makes some, but they're something like 600 GBP each (2 cylinders worth - so you'd need 3 of the...

Re: Hello from France - Project for an old british car and my own approach to HAL

What chip is supported best? I'd say none of the STM32, Sir! Support is barely started. ATtinys and ATmegas are much better supported. Is this just a HAL without any OS? How do you deal with concurrency/threads/etc if no OS or what OS do you use? HWA is totally independent of an OS. It is just an i...

Re: Hello from France - Project for an old british car and my own approach to HAL

Support for STM32F103 is barely started: you can configure the clocks (rcc), pll, systick, gpios, nvic (partially). I had started to work on the general purpose counters when I pushed the last commit. I would start the porting to STM32F4 if there is interest (I have a STM32F411E-DISCO for testing). ...

Re: Hello from France - Project for an old british car and my own approach to HAL

AS5047P is a 14-bit magnetic rotary position sensor is designed for high speed (up to 28krpm) angle measurement over a full 360º range. Why are things like that never used in OEM? Price? Reliability? I bought them from Mouser, about $18 each. It took 6 months before they could dispatch them... I as...

Hello ! I'm really pleased reading all the stuff you have put here. I was an electronics a long time ago when microcontrollers were not so affordable and I graduated in computer science. I am a supporter of free software and I personally use Linux based systems exclusively since 1998. About ten year...
