Hello !
I have this setup :
Prius Gen2 Inverter
Prius Gen3 MG2 , engine is a bit loaded with another one, which is connected to another Gen2 inverter (switched off )
60v LiFePo battery
board made with prius-gen2-v1.1.zip from johu's github

firmware 5.32
defaults loaded, resolver shows angle ...

Thanks !
It's really great to control all over CAN bus
I wrote an arduino uno code to send this control message via sparkfun CAN-BUS shield
you need sparkfun libraries and Ticker library to get it working

maybe it can be helpful for somebody


#include <Ticker.h>

#include <Canbus.h>
#include ...

If you have issues with data connection between modules then master module cannot receive any information from modules
am i right ?

Oh right, the binary on github doesn't have it yet.
So both modules are flashed ok and give you a running LED when reset and not connected to master unit?


Hello !
both modules give me running LED 4-1 slowly until i power on master unit
when master unit starts both modules stop blink then on ...

where to check it ?
I don't see it either in the interface or in the sources

when i set shuntvtg to 3400 it light up 2 diodes , as far as i can see, for second and fourth cells

I have properly connected most negative side to the first slave module
but it doesn't help
It can see only first module

Here is my setup
when i connect batteries slaves blink 4-1 slow
when i connect power to the main board they stop blinking and after 1-3 sec first slave starts blinking 4-1 really fast
second module does not blink
in the interface it shows only first module

Double check the slave boards are hooked up the correct way around. The first slave boards needs to be on the most negative side of the battery from memory. Also try switching the polarity of the data and power lines from the slave boards to the main board. One of those is labelled incorrectly ...

Hi guys!
I've made some main boards and some slave boards
I've flashed firmware to the main board and wifi adapter, so i can see smth
i've done all calibration

when i connect two slaves to main - main sees only first slave module
when i connect three slaves to main - main sees only first slave ...

I salvaged all missing parts for partially build board from original gen3 invertor board , and now it works perfectly with sine and FOC firmwares and Toyota MGR

The question is :
Have we lost our ...
