Hello Everyone, I'm trying to run olimex board in manual mode with no success. Always hitting over current error.
My setup is Olimex on DOT PCB with pins broken out for manual mode operation.
I have connected throttle1, il1, il2, motor temp, tmphs to 5 x 10k potentiometers.
And I've connected the ...

Update: Finally STK551U3A2AGEVB (Eval Board) arrived couple days ago and It works great.
I hooked up a 3 phase washing machine motor and Bluepill to the eval board And I powered the eval board with 64 volts (I don't have PSU any higher than that). Started the inverter in Manual Mode, adjusted ampnom ...

Thank you so much.

Can someone please explain, what is the need for bootupdater?
What is the difference between bootupdater and bootloader?
Do I have to upload all three files in order to get the inverter to work??
Thanks.

Hey Nailgg any progress on that how-to ??

I finally got PWM in manual mode.
Here's what I did To Start the Inverter in manual mode on bluepill, might help newbie like me.
Bluepill on breadboard with 5v, 3.3v and GND pulled out.
Pull B1 to 3.3v , B7 to 3.3v , and B6 to 3.3v momentarily. (B1_ MPROT/UAUX), (B6-Start),(B7-FWD).
Pull B8 to ...

Hello Isaac96, thanks for your reply.
FWD pin is pb7 on bluepill, I tied pb7 to 3.3v still got no pwm output when I enter start 2 on terminal, I get response as Inverter started but no PWM output.. And also when i type get dir it says 0.

Hello, I've got response from the bluepill.
My Current setup is Bluepill connected with USB to TTL Convertor, I used Putty on linux ubuntu for serial terminal.
I cant seem to start inverter in manual mode, typing start 2 on the terminal gives response as Inverter started, set fslipspnt 10 , set ...

I have flashed my Bluepill with a USB Bootloader and when I flash it with stm32_sine.bin the green led stays on.
Where do I find the bootloader which supports stm32_sine firmware ??

Thank you kind sir.
My battery pack is 110v and 45ah.

I've stopped doing all of the mechanical stuffs as of now... once i build the controller myself I'll scale it up or down as per my requirement. Just getting my hands on embedded and electronics as it is way more interesting.

The board in the picture seem to be missing some components, gate drivers and also 3pc 33k resistors. Mabye the picture is taken before these where mounted?


Yes, this is the extra board I have lying around so i took a quick pic with this.. Other board is same as this but fully populated ...

First of all thank you so much for replying..
Ofc my ultimate aim is to power a electric motorcycle. For that I'm learning embedded systems, I have made a simple power stage, which i thought it would work but unfortunately it spins a motor for a second or so then it stops.. I'm guessing no feedback ...

Some of us can't find a suitable brick modules especially I would like to learn about building power stages by myself.
And I dont want such high power output... The absolute maximum I'll use is 10Amps max.
Soo.. someone please explain what are all the parameters should I have to look into to ...

I'm working on a simple H bridge module, may I know what is the DC/DC converter used in the Gate Driver board ?
