Please create a separate thread for your board. And also post several large detailed photos of both sides of the board, so that we can see which components are populated. And please give more details, like what is the current consumption of the board on 12V supply?

Don't turn on the board until you solder all required parts, especially small capacitors & resistors.

Nice progress! Keep it going!

The total component cost for my Prometheus board was certainly under $100, and most components were available at local stores (imrad,kosmodrom,rcscomponents). Also, I could solder STM32F405 if I wanted, but I decided to use STM32F469, just for fun. Therefore, the only exception is MAX9926, which is ...

But no free compiler anywhere in sight.

Maybe all is not lost with that Sh*tBuddy?

The answer is blowin' in the wind? (с)

We have success! I switched back to SimplePwm, (sketchily) wired in my hbridge, and now I have smooth motion, including throttle body spring correction! This is a 99% port of my Arduino code, down to the curve for the spring compensation and PID tune constants. It's running 500hz PWM frequency, and...

Another option for inter-module connection: pcb edge connectors (like PCI-E): https://media.digikey.com/Photos/TE%20Connectivity/2-1761465-1.JPG Less solder joints and less assembly efforts, and still 1.1A current rating per pin, according to the specs... Examples: 64-pin connector for $0.7: https:/...

Another option found: AD7328 x 2. A 12-bit 8-channel 1MBPS ADC with 10V-tolerant bipolar inputs (has built-in clamp diodes capable of 10mA per each channel, so a series resistor array would be enough for input protection). Pros: Small package (TSSOP-20), fully integrated (built-in 2.5V reference), c...

Hi! @Russian asked me to drop a few lines about the replacement of analog circuitry (opamps), digital inputs and... vr-interface. The first candidate is ADS7953-Q1, 16-channel 12-bit 1MBSPS SPI ADC (automotive grade). Moreover, it has a programmable built-in comparator and GPIO outputs - potentially...

В мануале саабовского ЭБУ Trionic-5 (http://www.rossonex.com/SAAB/Trionic_5.pdf) на 59-й странице и дальше подробно рассматривается работа ПИДа ХХ и нюансы реализации и настройки. Например, описание влияния коэффициентов на поведение РХХ: pid2.PNG Пример 2d-таблицы коэффициента P по оборотам и давле...

а какую цель мы вообще преследуем, когда играем с этим ion sense? Например, вот три цели: 1) Диагностика пропусков воспламенения (и потенциально индикация необходимости замены свечей, поцилиндровое отключение впрыска/сушка и т.д. - надо изучать, что умеют делать крутые ЭБУ); 2) Обнаружение детонаци...

Первые испытания ion sense. Часть 2. Идём дальше и добавляем в прошивку примитивный тестовый код чтения этих сигналов: patch-ion-test.patch Что он делает: - подцепляет на внешние прерывания обработчик входов воспламенения (на базе кода джойстика); - каждый такт собирает статистику по сигналам воспла...

Первые испытания ion sense. Часть 1. Имеем вот такой набор саабовских запчастей: ion1.jpg - Блочок Ion Sensing Module SAAB 55352173 ("цифровой"); - 4 новых катушки 12787707 (китайские DMCOIL); - проводка с разъёмами для катушек (б/у); - коннектор для блочка и контакты к нему (аналог Tyco 1...

Btw, why is your advance angle negative ? Like -17 degrees in the video? Is it normal? :shock: I don't know whats best to set up engines, never did that. Im not sure if TDC is the real TDC at my engine . I don't know why @Russian didn't react on this... And I don't know why on earth we still have w...

Here are raw wfms for people having an rigol scope. Just use Storage -> type Waveform, > Load. https://ufile.io/9s7nj Could you please give a short text description for every file name in the archive (including the channel legends)? For instance, what's in c1d4.wfm, i14.wfm and ie234.wfm ? What's t...

From the SAAB manual for Trionic 8 (2004 model): So as I can guess, Trionic 5 and 7 used an analog ion sensing module for CDI ignition, but newer Trionic 8 is an ordinary coil ignition system (primary/secondary winding on the schematics above)?..

Very nice, congrats! Can you upload your current TunerStudio config files? And maybe some logs? Btw, why is your advance angle negative? Like -17 degrees in the video? Is it normal? :shock: For better cranking, you may try tuning postcranking enrichment and aftercranking IAC duration settings: after...

see !compile-prometheus.bat to see how different configuration is selected.

The "!compile-prometheus.bat" is for Prometheus with 469 chip.
For 405 chip, you need to replace "-DSTM32F469xx" makefile option with "-DSTM32F405xx".

Yes, it comes from coil itself. I will record all the data on weekend as i am now far from my workshop. There will be a load of videos.

Can you disconnect the ion sensing module and record the signals from and to the coils?

how does starter blocker works, i mean from what i understand trigger the starter motor?!?? but whats the input? and how do i configure it in software? For starter blocker you may use FSIO, it's very flexible! For example, just set this expression (in reverse polish notation): rpm cranking_rpm < in...

do you have any assembled board to sell?

Unfortunately, no...
But I have many detailed photos of assembly process!

2018-11-17 20_27: : startedToOpenValue = 19.5, reached100Value = 26.0
2018-11-17 20_27: : startedToCloseValue = 13.5, backToZeroValue = 8.0

pid.offset = (startedToOpenValue + startedToCloseValue) * 0.5 = ~16.5

#3 Yellow/Blue analog magic

Why do you call it "analog magic"? We already know 100% - that's a knock detection analog signal. If the voltage level is low, it means there's no detonation. It seems that the system works just fine.

Only one or the other is being used .. Yes, but you'll have to put some additional traces and footprints for those alternatives on pcb, and the high-voltage clearance rule will be broken, for sure. The more dense traces and footprint you put, the less voltage can be applied. High-voltage pulses wou...

Я так понимаю это будет работать только с определенными индивидуальными котушками и дополнительной магической коробочкой ??? Скорее всего, да. Вроде как идея заключалась в том, чтобы измерять ток в момент искрения (пусть преобразовательная часть ток-напряжение будет "черной коробочкой") Д...

Мысли вслух по использованию входов Прометея для будущего проекта Ion Sensing (вариант реализации): 1) Исходим из того, что у нас освобождается триггерный вход датчика фаз и аналоговый вход датчика детонации. 2) Два сигнала воспламенения C1 (1+3) и C2 (2+4) подаём на входы ЭБУ CAM+ и IN2 по такой сх...

Thanks ! Maybe i could replace with a non inverting buffer ? Be careful when you choose an alternative - it should be capable of 3.3v input and 5v output (HCT series etc.), i.e. act as level shifter... But it really makes no sense because the output mode is fully controlled by firmware. And inverti...
