Yet another stupid software bug I'm afraid. Thanks for testing. At least now I have a test bench setup and am actively working on the toyota systems so hope to have a bug fix release soon and some setup videos. Sadly it looks like most software updates didn't get tested.

To be honest I'm probably going to roll back most of the changes as I just don't have the C++ skills to unravel the new way of handling inverters and vehicles.

Hrm, pity I don't have mine running on bench yet. So its like you know what needs fixing but the fix itself is the issue. If you detail out the changes that need to be made I'm sure a few of us can look at the code and suggest how it needs to be implemented?

What about branching from here https://github.com/damienmaguire/Stm32- ... 4ddd30e3fc which seems to predate some large refactoring and putting the fixes on there? Just a thought.

Happy to be able to test. At least now I'm comfortable that things are wired correctly, I can make a harness and get back to putting things together.

I’m also just about at the right point to do some testing if it’ll help. My GS450h inverter and drivetrain is out and on the bench and my ZombieVerter is nearly complete.

Thanks. IS300h system now working with full throttle control so will be porting this to the Zombie and cleaning up the gs450h class.

I'll take that as a no? Added some hardware economizers now anyway. If I understand right it seems that building the project isn't straight forward at the moment, and neither is using it for GS450. So we will stick with the older version for now but it would be good to be able to update to, and contribute to the main project at some point. Cheers

Essentially correct. Sadly in my absence the firmware has gone through quite a few modifications without the benefit of testing. I am quite literally working on that right this minute and expect to have an update in the coming days.

GS300H system now working in the vcu. Also quashed quite a few big bugs. More to do and also test but hope for a tested release binary by weekend.

Awesome!

Random question - how is the current limit working at the moment? Was driving around a good bit today and experienced hard cut on rev limit (can live with that) but it also feels like a hard cut when you hit the amp limit, which would preferably regulate at the setpoint.

Th rev limiter is indeed intended to be hard cut. Not so the current limits. Looks like another bug for the list:) Good news is I can actually test that now. Speaking of bugs bashed out a few today and nearly have all the GS300H data working well like rpms, temps etc. There were a few real sillys in there. Anyway, going to shoot some video of the 300h then wire in the 450h for test and debug.

Bad news I'm afraid. The 450h module is still bugged so release will need to wait a few more days for testing.

I love getting these updates, it's much better to hear, "delayed, still working on it" than silence.

I've only been silent when dealing with house move and renovation. Trying to pick up the pieces everyday now:)

Following quite a few requests (and an easing up of parts supply) I am now offering a built and bench tested version of the VCU kit :

Oil pump not working on gs450h bug fixed.
Toyota inverters not re init at key on fixed.
Will have a friend with a 450h build test then we are good to go for release.

Thanks for this Damien. Looking forward to seeing mine spin for the first time.

Awesome. I just took you up on your assembled one.
Need to learn. Starting from the basics.

Last thing on the bug fix list is to reinstitute the ISA shunt init routine then once the 450h routine is verified in a car we are good to go on the bug fix release. In the meantime I'm wiring the bench 450h rig to begin work on gear shifting implementation and hunting down a deal on a gen3 prius transaxle and driveshafts so we can test and debug the prius option for fwd projects.

R14 missing.

I’ve only just spotted that R14, a 1K resistor (R0805), is missing from my board. Is this deliberately omitted because it’s not needed or should I get one and add it?

From the schematic it shows as part of the gear feedback input so perhaps it isn’t needed at the moment but, once Damien has enabled the gear shifting, it will be required. It’d be helpful to know if I’ve interpreted that correctly. Thanks.
