Tried it, doesn't work. Speed info is much less accurate than position and thus distance info. Yes, because speed is the distance component * time component. So distance = 0 would be then speed=0. Did you try distance =0? To let this work better we would be helped with an inclination sensor... :D I...

my point is that early boards have for sure the WAKE functionality hence i selected the MCP2003 version.
When i'm at LIN territory i will start with the driver.

Maybe a strategy would be to opt for zero speed instead of distance traveled. And don't forget to include windows for small errors. Also a maximum torque and speed would be wise to implement. (While in this mode). A counter option would be handbrake release request from the drive unit. But maybe tha...

@Damien can you comment on this?
Is there a difference between V1 and V2 boards?
Are both versions available on Patreon?

Any updates?

Do we already use one of these? https://nl.aliexpress.com/item/1005001830729354.html?spm=a2g0o.productlist.0.0.527262682cMSIO&algo_pvid=c9c92ede-1703-45e5-9171-22aa7b365765&aem_p4p_detail=2021113011380114404716206570160002897432&algo_exp_id=c9c92ede-1703-45e5-9171-22aa7b365765-24&pdp...

They worked perfectly up to my latest purchase when OBVIOUSLY something was changed either by Olimex or by Espressif and naturally no one wants to find the issue as all the silly little arduino sketches work fine.

I would agree too. I would like to suggest you feed it a contact +12V so only live if key is in contact / car is switched on.

Hey nice job! Regarding your problem I would say we need to know: which version of the software and upload your config.

no production EV actually responds to the EVSE power limit reached, current limit reached, and voltage limit reached. Shocking, I know. It also depends on interpretation. It could be pure informational. Also it could be that like "target values" are reached. Or like damien implements, as ...

Ok cool! I'm building the Bootloader GUI app right now. Current speed is like +/-12 seconds to program 27K but i have some tricks on my sleeve remaining. I think its the host pc limiting the speed not the uController. (each msg invokes the GUI currently and that's expensive). (how big are our invert...

Ok next step is validating the v2.0 design and adding more data.

Ok i optimized it a bit i now reserve 8K in the loader.

This is my contribution to the community of OpenInverter.org.
Enjoy!

No not yet i finished it last night.
Didn't optimize yet for size.
It uses both libraries cm3 and inv.

Well, for example checking that flag that never shows on GD would be one way of auto-detecting. [/quote] How reliable is that though? remember my VCU would sometimes start working if left long enough, I'm very much guessing but maybe it was random noise that just happened to look like the flag?????...

As per title! Couldn't find anything available so took the bootloader from Johannes and modified it towards a CAN version. Build a GUI and the rest is history. The CAN Interface used is a profi one from PEAK Systems. https://www.peak-system.com/PCAN-USB-FD.365.0.html?&L=1 Didn't optimize yet for...

Ahh ok i meant proximity indeed. But the LIM reports it so i would solve it by CAN if that works.
Or as you suggest by relais (DPDT ) (fast charge/ac charge).

If I'm correct the wire is split/shared towards the charger and the lim.
I know that the LIM canbus sends 3b4, so the data is available the charger could be 100% canbus.

On request I will build a SIMP BMS version for the Taycan Battery.
So stay tuned and it will be supported in SIMP BMS.

See: viewtopic.php?f=3&t=2002

Update: If offcourse its needed!

Do you have a partnumber? And do we know which version this is?
(Max current?)

As I have said in videos and on here multiple times if you are not proficient at this type of soldering then lookup a phone/laptop repair place in your locality. Bring the board, parts and the info from the wiki. I know of others here who have done this successfully. Yeah indeed. The local TV and R...

Did we test the LIM's limits regarding coil resistance? My eyes fell on 11.0 Ohm coils. I know we state 15.0 Ohm as default but I like to keep things standard and not go with a relais in-between trick which would mean I would need to economize the 11.0 Ohm relais. Maybe we can change something simpl...

Will you update your GitHub with the latest schematic?So we V1's know the difference? Also there where some design corrections.
Maybe we should note them in the wiki.

I will try as promised to take this task up on me I can't promise I'm fast enough doing it though.

Ok I made some corrections and ordered V2.
I also confirmed that the GD32 chip is working with the current firmware.
