the DS1054Z can read SPI, along with a few other protocols

I am starting to sketch out the flowbench design..

I know it can sometime be pulling teeth to get people to commit to a project, but certainly glad to be a part of it.

Just purchased the KIT33816FRDMEVM through NXP directly..

was a couple bucks cheaper than through Mouser (thanks to added tax).. Stock shows as Pending for NXP, so hopefully they'll report they have it and ship it out, otherwise I'll go through Mouser..

That kit does seem like a good way to go - I would have preferred the other one as it didnt have the Freedom board and I could have just used the Frenkenso directly (gaining more exp with interfacing with it), but hey, no worries, not like they are charging more.. I have seen some datasheets that se...

I will absolutely post all progress of use of the chip on that thread.. I should actually start a thread (sorta what this is - actually this was more of the 'Hello' and what I am gearing towards) for my efforts on this engine. I figured that is what the pump bank was for, was simply trying to unders...

Also, not a big deal that the IC can do more so why not have a PCB capable, but no need for my instance to actually populate it - at least from what I know about it right now..

@kb1gtt What is the purpose of the 'pump bank' ? Electric motor that drives the pump(or electric pump itself) ? Not sure I will need that. I will have to rig up the pump which is driven by the timing chain to a separate motor for the testing, either through a chain (requiring a gear to be made for t...

Okay, yeah, that appears to be the case.. that's actually really neat!

My only idea of going with an external HV PSU is for a more stable (multiphase) output. Looking through the datasheets etc I do see that of the 5 highside drivers, 3 are referenced to a max of Vbatt while the other two can be referenced to Vboost.. Then you connect the high voltage side to the high ...

Alright, joined up, and yeah I see not much has happened in the general chat for some time.. no worries.. I was more so trying to go through a block/logic diagram of what is needed for the injector drivers (in my head).. Stable HV PSU, capable of, let's use some values from NI9751 doc.. 75v peak of ...

Also curious, is there an IRC channel ( or slack or similar ) ? Smaller questions (that may not warrant much archiving) isnt always meant for forums.. I usually hang out on FreeNode (recently rejoined ##electronics for the questions I will have, and idle in many more) but appears no one is in a #rus...

Also came across this from National Instruments.. http://www.ni.com/pdf/manuals/375969a.pdf Beyond what one person could consider cost effective.. but they show a decent equation there and sample values for determining power ratings and so forth.. I havent looked into your [kb1gtt] board in depth fo...

neat @ scopes.. I was looking into the new Cummins R2.8 crate engine before telling myself that I need something smaller, not a rock crawler.. and those crates work out of the box for a reason :) and yeah, hot air for SMD reflow stuffs I need to start looking into the rusEFI codebase.. I will likely...

for the money, likely looking at the Rigol DS1054Z, 4ch 50mhz (upgradeable/hackable to 100mhz) ..

Unless convinced otherwise..

I do have a bit of electronics background, although my supplies are currently low. I've been "using" LTSpice for ~12 years or so at this point if that gives you any idea.. Haven't used KiCAD before as I learned some basic circuit design w/ Eagle - but I hope to switch over.. My mother is a...

Hello All! I am in the process of researching Open ECUs for rigging into a very modern diesel, common rail, direct injection, engine. The specific engine (LH7) that I am looking at interfacing with is loaded with sensors - and I have essentially obtained the full service manual - which is good since...
