Not sure what it is. Probably some hint of http://rusefi.com/forum/viewtopic.php?f=4&t=381 ? That's still WIP

For now you would need stm32f4discovery - this name is also the part number.

On the SD card sch page it shows some diodes called D351-D353. No listing in the BOM for them. Are they needed? Great question! These are 5v power supply, 3.3 power supply and 'usb connected' LEDs - these are useful on the individual modules, the pieces Frankenstein was made of. I would guess there...

Did you destroy something on the PCB or just the op-amp chip? Without U201 you are limited to 8 channels including hall sensor input and you have more then 8 inputs in your list. Anyway - yes, it's trivial to re-map the channels, so we can use the 2nd chip to begin with. Can you please get TPS and M...

So this file was generated based on three point - same Steinhart-Hart approach http://rusefi.com/articles/measuring_temperature/Steinhart-Hart.shtml ; Input Data: Temp, degF Resistance ; 50 58750 ; 104 16150 ; 212 2070 With such input data I believe that the values below 50F are not really accurate,...

How's this for a start? That's a good start! Only thing: temperature sensors, what happens below 10C? I am pretty sure that you have at least one month each year below 10C, don't you? I am planning to use the fancy equation which would be based off three point, so ideally I would need -20C, 60C &am...

There was no 5k on the BOM because for some weird reason 5k resisters are unreasonably expensive on digikey.

I've just updated the BOM with a 4.99K which would work just fine.

Let me welcome you into the "Electronically challenged of the world, unite!" club. You do not have to adjust your signature, but you can if you want to. Fuel injectors are controlled by connecting and disconnecting their GND wire - the +12V is constantly routed to the battery. So, you woul...

Sounds like a plan Let's begin with #1 CLT. Need info on your sensor. Is it the usual pull-down thermistor? If so I would need three resistance values at three temperatures. #2 IAT. Same #3 MAP. Need at least the part number or the coefficients if you have them #4 Barometric - the same #5 TPS - if t...

Reluctor as in "Variable Reluctor" (VR)?

You would need the MAX9926 chip from the BOM.

Can you please email me the log file? It's in 'out' folder next to the console .jar file - file name contains console launch date & time. Without zooming in this looks as it just works? That's too good to be true. Something should be wrong somewhere... Q: what do we do next? Assuming we have tri...

Mazda_B_engine is starting to dominate here

Glad to you have on board!

I know, we will use the MAX chip circuit. Problem solved?

VR chip alone costs something $8. VR chip is requited for VR sensors. VR chip can handle Hall and Optical, but it's cheaper to use plain op-amp analog input circuit. But that's only true if it does work - it works for me on my Aspire and it's the only installation, the red Festiva with a 323 here is...

Do you have a printer? Because if you, you can print Schematic.pdf and look at it page by page... Please tell me your wiki login (separate registration required) and I would give you Write permission, you would be able to improve the Frankenstein assembly page. PS: can I move this thread into 'your ...

BTW there is also a 'compact' version - same data, just aggregated with qties https://svn.code.sf.net/p/rusefi/code/trunk/hardware/frankenstein/digikey_parts_compact.csv

There are more then two resistors in the BOM. Current version - https://svn.code.sf.net/p/rusefi/code/trunk/hardware/frankenstein/digikey_parts_full.csv - has a the full list. If you want to cherry-pick, the Frankenstein wiki - http://rusefi.com/wiki/index.php?title=Manual:Hardware_Frankenstein_boar...

I think that's a harness-to-harness connector, like from wires to wires. Which should work if you solder some wires to the PCB

Delphi Packard Bulkhead connector Kit - this looks like a harness-to-harness connector?

I use www.ebay.com/itm/121122884285 and we have a board for this connector - we have a board for it http://rusefi.com/forum/viewtopic.php?uid=2&f=4&t=507

I've realized that we do not have a thread for the 176122-6 connector board - this board was finished before the forum was created. https://github.com/rusefi/rusefi/tree/master/hardware/Breakout_64pin_176122-6-Connector 176122-6-connector.zip Also available at our store http://rusefi.com/hardwave/17...

AFAIK there is a difference between VAF/MAF and MAP logics. Air flow meter you just take analog value, but for MAP it's more complicated - you need multiple readings withing a particular windows of camshaft angles and then you average these values. So, there is some extra code which I've kinda start...

This case you would be a MAP trailblazer. But yes, same bare essentials - sensors are just analog input channels. That's to the best of my knowledge.

PS: skeeters_keeper , need your help with something. I need the log file of that noisy run - I want to look at the numbers & see if software filtering is an option. The logs are in you 'out' folder, the file name is the time of log start. Worst case you would need to re-create that situation :)

You would need some boards - you have to decide if you want to go with individual 'modules' - small analog PCB & small injector PCB (this one can drive ignition, too), or you want to to use the http://rusefi.com/forum/viewtopic.php?f=4&t=359 board, or you want to make your own board out of s...

I like these pictures :) That button with the plus on it is zoom in, can you please hit it next time you try that? So that we see say 6 to 12 waves. Just to see the lack of noise. Now a separate question how we will apply the comparator approach to the existing boards? So, do we need to adjust the b...

HIP9011 часть выделилась в http://rusefi.com/forum/viewtopic.php?f=9&t=505

Maxi wrote:данные в цифре можно снимать по SPI. это сильно меняет дело вообще...

Это значит ему придётся выделить целый SPI, чтоб данные от него не пропустить? HIP просто публикует в SPI когда что-то ловит, или он всё-таки отвечает на постоянные запросы МК?

я тут осознал что у http://rusefi.com/forum/viewtopic.php?t=357 был плохой заголовок и его не было в списке тем по железу - добавил в список русских тем.

I guess I should get it once there are five engines running rusEfi?

Кстати да, драйвер DMA не будет доступен в момент краша rtos. А прямо прямое управление пинами 20x4 никуда не денется. @, спасибо за напоминание!

Пожалуйста, присылай патч Идей много, работников - полтора.
