I have not tested sending CAN-messages to the OpenInverter specifically so my answer is a general. There is proably nothing wrong with the While loop in setup as this is a common way to setup the mcp_can. In my code for other projects I normaly use this line in the while loop: while (CAN_OK != CAN.b...

What do you mean by 120V? Nominal or maximum voltage? The FET mentioned IRFP4568 has a 150Vdss which leaves a small margin for voltage spikes. To be more safe I would look for closer to 200V transistors. One option could perhaps be IRFP4668PBF. If you want to use modules I think IGBT:s are the way t...

Thats even better as that is the setup I plan to use, Yaris inverter with Damien's board. Right now just doing som testing.
Martin: What battery voltage are you using?

Found the parameters for the MGR here:
viewtopic.php?f=14&t=488&p=11431&hilit= ... ers#p11481

If this still is open I'm up for 6 modules.

I just bought a MGR and started doing some basic testing with a Honda IMA inverter and a "blue pill".
Does anyone know, and like to share, the motor parameters for this motor? Number of polepairs, Resolver polepairs etc.

Hm, I've made some progress, I think.
Did:
stm32flash -w stm32_loader.hex -b 115200 /dev/ttyUSB0
stm32flash -w stm32_sine.hex -e 0 -b 115200 /dev/ttyUSB0
Now the onboard green led blinks!

Update:
It works!

Thank you for all your help!!

Ok, thanks, that explains alot!
I've just tested the hardware and it works.

Please, can you tell me how I upload first the bootloader and then the firmware, without erasing the bootloader, using stm32flash.
I guess -s option is needed but at what adress?

Yes, uart3.
If I flash the bootloader the stm32 sends 0x2D, as expected.
The firmware does not require the bootloader, correct? The firmware can be flashed directly on the blue pill bootloader?

I will create some simple arduino sketch to verify that the uart3 is working correctly and post when done.

I'm new to this forum, to this inverter and to STM32/ESP8266... Trying to use a "blue pill" and an Olimex Mod-wifi-esp8266 to do some testing. I have programmed the ESP with arduino ide and can axcess the web interface ok. It sends out serial data when I use the "send custom command&q...
