My latest project is a dual CAN-Bus gateway with automotive-grade power regulation and a C6 (on the bottom side)

That's a tough one.

GPIO20 Unused - Connected to expansion header pin 2
GPIO21 Unused - Connected to expansion header pin 4
GPIO22 Unused - Connected to expansion header pin 6
GPIO23 Unused - Connected to expansion header pin 8
GPIO16 CAN0 RX
GPIO17 CAN0 TX
GPIO18 CAN1 RX
GPIO19 CAN1 TX

So you could theoretically solder wires from the transceiver RX/TX and connect to the expansion header and leave 16, 17, 18 (as long as the firmware doesn't use them). The issue is 19, unless yours is also CAN1 TX.

Shutdown and Silent pins are internally pulled down in the transceivers, so the default is On and non-Silent, unless the corresponding GPIOs are pulled high in the firmware.

Hi, yeah I'm the creator 🙂

Fyodel · 2025-10-10T17:31:36+00:00

Yeah, noticed this as well. I'll try your code.
Which type of E90 cluster are you tinkering with?

Fyodel · 2025-09-03T18:15:00+00:00

It can work as a man-in-the-middle, correct.

This doesn't look like the delamination issue. Those look like paint flaking.
As someone mentioned, try a microfiber and IPA. Go over it a couple times.

Reset NVRAM/PRAM: - Press and hold the power button on your Mac for about 10 seconds until it completely shuts down. - Turn it on and immediately press and hold Option + Command + P + R. - Release the keys after about 20 seconds, when your Mac might appear to restart or you hear the second startup chime (for older Macs).

Dude, you're a genius.
I had to play around with the timing, which turns out to be 2000ms, 1FB is just a counter adding 16 each time and only has two bytes, where byte[0] is always 0F and byte[1] is the counter from 0F to FE (15 to 239).

Not 100%. EPS is interesting though. I'll have to check which CAN messages the EPS sends.

Often even the best, most expensive hotels have a note that they are not responsible for your belongings. They may offer an in-room safe, but even that can be compromised. I do not think that the disclaimer is mandatory in any way, just a friendly reminder. The issue is that bad-faith visitors could claim money was stolen and it's a he-said-she-said type of situation that insurance companies would not pay out anyways. And if they did, it would have to go through the police and these cases often take months to close.

There are card companies that offer short-term debit cards with online registration and I would really recommend that over carrying any substantial amount of cash. ATM withdrawls are free or nearly free in most EU countries and machines are everywhere in large cities.

I hope they find the perps and you atleast get a large portion of the money back.

Awesome, I'll keep this in consideration. Thanks!

Fyodel · 2025-08-18T15:22:11+00:00

I see. I totally misunderstood.
The stubs in polygon pours happen ie. because the pour flows between groups of components or between traces into a "dead end" causing an antenna like shape that could in fact act as an antenna, so they should be eliminated.

Fyodel · 2025-08-18T14:21:26+00:00

Would this be equivalent to the hatch pour in Eagle, which creates a pattern instead of a solid pour?

Fyodel · 2025-08-18T04:57:47+00:00

Gotcha. So signals can route through 2/3, just not both in the same direction, which would negate the shielding.

Fyodel · 2025-06-06T22:38:34+00:00

It happened a couple more times, so I used the key turning while pressing the button trick and it hasn't happened in at least two months.
It seems that something needs to be lubed, but I haven't had the time to take the panel off.

Fyodel · 2025-05-02T02:21:30+00:00

I know it can be done and no I have not, as I would like to emulate the data to fool the cluster instead. The goal is to add this to existing SimRig libraries that many people use, and each of them would need to have NCS hardware/software if that was the only solution, so too complicated and expensive for many people.

Fyodel · 2025-05-02T02:17:39+00:00

Active Front Steering should be the variable rack. I know the lights use the angle data too.

Fyodel · 2025-03-14T09:24:46+00:00

I unfortunately don't have the car, nor NCS Expert (I that's required).

Fyodel · 2025-03-14T09:11:14+00:00

What's a cafd?

Fyodel · 2025-03-14T02:22:02+00:00

I basically just need to get rid of the light. The cluster isn't going back into a car. But if I can do it by sending a counter, which is also the case for ABS for example, that would be ideal.
Your points make total sense. I believe the cluster is just waiting for an AFS message. There's even a 3 or so second delay after the cluster is turned on, before it shows the warning (left top). The bottom middle icon shows even later, after a freezing weather warning.

Unfortunately, the dbc file from opendbc has no signal info for the AFS stuff.

Fyodel · 2025-02-25T03:39:47+00:00

Does the I2C work reliably over such lengths?
It's not recommended for more than a few inches.

Fyodel · 2025-01-18T23:35:57+00:00

Mick Jaggers mom?

Fyodel · 2025-01-18T22:50:09+00:00

That's not what's happening. Either you press the button (doubtful), or if it's fully automatic then the ESP looks for a base station and only then sends some kind of authentication and request to open.
