[info] Proteus - Waterproof, High-feature ECU!

[Lambo97]

I'm new to the hardware development scene but why are we looking for a new chip? Are we sure the current one is going to be unavailable? If you think so then from what Mck1117 is saying the new chip seems unusable if the config will eat most of the memory. Do you think there will be a workaround or are we looking for a new chip? Like Andrey said Drama...!!

The semiconductor industry is kind of a mess right now. Lead times are long, and stock is unpredictable. The swapped out chip is actually slightly better than the previous one, and there's no permanent swap planned. The normal one was out of stock, so we went to an alternate. Functionality is the same on the F7, with a 20-30% faster CPU and more RAM to boot.

I didn't realize the behavior on the 1MB devices before placing the order - we had to change a few things since we'd only used 2MB STM32F7 chips. With those changes made, the flash space available is identical to all of the STM32F4-based ECUs already out in the wild, including most Proteus boards in existence. 256K (1/4) for config, the remainder (768k) for code/data. Currently only about 2/3 full.

Hi there, just wiring up my car almost done. To run the Proteus in full sequential do I need to connect the CAM sensor to VR_2? You sent me the board with 2 VRs so 1 is used for the crank sensor and I'm guessing VR_2 can be used for CAM correct? or am I connecting it to one of the analog inputs? Thanks,

[mck1117]

Any channel can be used for any function. You can pick in TunerStudio where each function is wired, and the software will remap everything internally.

To answer your actual question: it depends on what kind of hardware your cam sensors needs - if it's a hall effect sensor, pick any digital input, and if it is indeed VR, then VR2 is the place to put it.

[Lambo97]

Sounds good, I see Andrey wired up a digital start wire to the Proteus. I plan on using old school key direct to the starter. Does the Proteus need to see the key in crank position, or will it naturally pick up that the engine is turning and then start firing the injectors and coils?

[mck1117]

Starter control isn't required. If the engine spins, rusEFI will run it.

I can't found IBOM for proteus v0.6 ...

Is any way to generate it "by myself" form github clone ..?
or can anybody public it on https://rusefi.com/docs/ibom .. ??

Thanks for answer.

[JRD McLAREN]

.. I got it ...

[JRD McLAREN]

Uf ...
It's problem with processors ... NO STOCK ...

Which other than STM32F429ZGT6 can be used in proteus ..??
I'm found NUCLEO-F429ZI with STM32F429ZIT ... but..."it is good idea buy dev kit, desolder CPU" .. . .

Highside BTS4175SGA are"out of stock" also .. and I can't find any replacement ...

VNLD5160 is replaced for BM2LC105FJ..
Can interfaces for TJA1042T/3
..and many others ...

[mck1117]

Highside BTS4175SGA are"out of stock" also .. and I can't find any replacement ...

some batches has BSP762/ISP762, it's interchangeable for us

TODO organize info a bit better on https://github.com/rusefi/rusefi/wiki/Chip-Shortage-Parts-Interchange

No fun ... all Infineon's FETs or IC are gone ...

Andrey, I'll make any spare / exchange list of IC / FET ...
..if it arrive ..

With parts shortage what is the complete list of MCU options official firmware would run on?

Matt does Proteus require 2MB of flash or would it work with just 1MB? Is the official build using 180MHz or 168MHz?

Ideally let's document on https://github.com/rusefi/rusefi/wiki/Chip-Shortage-Parts-Interchange#proteus-mcu-options?

2MB not required, that's what the stuff around the 1MB F7 0.6 changes were, so now we properly support 1MB F7.

We run F4 at 168MHz, since there's no way on an F4 to run at 180 with USB working. All F7 are configured for 216MHz, since their clock setup is different and allows for USB at different CPU speeds.

I'm found some big mistakes ...
Bad traces on front layer..

Please check official fab files. There is an opinion that there is no bit mistake at all and you should press B to update fills.

I would agree that that's a small avoidable confusion

[JRD McLAREN]

OK...
I'm not so good in KICAD ..

This is from github repository .. and, I have no idea, what is inside gerber files - export directory
I found this, cause I have different component size on PCB and different on IBOM ..

[JRD McLAREN]

strange...

[mck1117]

The pcb in master has some minor changes (swapping to use more of the same component) that have never been fabricated. If you would like to fabricate a board, please use the latest release (0.6) as those files are proven.

If you really want to use kicad, the problem in master is that the copper pours need to be updated - just press the B key and they'll recalculate.

I have some boards on my desk.. and it looks good ...

BM2LC105FJ-C is replacement for VNLD5160

BM2LC105FJ-C is replacement for VNLD5160

can you please post pinouts for both? i recall there is an opinion that pinouts are different?

he's right, there are two pinout options for that family of chip from ROHM, and it looks like the BM2LC105FJ-C does indeed match

[AndreyB]

Nicccccceee!

[mck1117]

specs look very similar to the VNLD5160, should work just fine

and ISP752T.... for High-Side switch

[mck1117]

and ISP752T.... for High-Side switch

lower current, 1.3A vs 2A, but yes

[JRD McLAREN]

150mOhm vs. 70mOhm
.it will be OK for many applications...

One board almost completed ... second still wip ...
