I updated files in my ESP32 repository
https://github.com/arber333/ESP32-VCU/tree/main

Search for the latest version 2.4 and 2.5
2.4 is meant for application with 2x CAN ports controling chademo fast charging or receiving BMS updates
2.5 is simpler, only single CAN but it can drive more PWM ...

I love the new 2026 calendar :D

I already have my ESP32 VCU interface ready.
Dual CAN
3x protected outputs
5x ULN2003 outputs
5x digital inputs
2x analog inputs via the ADS1115 i2C interface

I only need to provide the code... i am only a ME so very slow in coding... :oops ...

Hm... strange

I connect car saux battery with ignition so i provide inverter, OBC and heater with 12V so it is more than 1A.
But even if i provide 12V and 0x285 telegram i only get response from inverter is when i give it HV via precharge process.

To verify this i use ECAN USB interface

Thanks
Then was anything wrong in the beginning , i had only 200mA

Now the world has loosing the Game
in the Future we drive the Outlander Engine with ESP32 Web Interface

Don't let the mouse slip out of your hand when accelerating.

Connect 12V power to IGCT and 0V to GND.
RSDN should NOT see 12V when in normal operation!
You should use a propper power supply, 5A at least. I suspect inverter can go into brownout if not enough power
When you connect to CAN H/L you need to terminate connection on at least one end if not on both ...

Try switching can low/high around there's some contradiction on the wiki when you look at both diagrams

I swapped low and high, but I don't think it's related to high voltage.
I'll have to test it again. Everything from the inverter is dismantled, I can't find any faults, it looks like new.
I'll ...

Hello
I'm new (not to world)

I'm trying my hand at the inverter, first reading out CAN bus data as with the charger.
Unfortunately, it seems that this is not so easy, or the rear inverter is broken.
My approach so far:
Connected to the grey inverter socket as in ewiki.
GND, CAN H L, IGCT, and RSDN ...
