Kunteng controller programming pins

[basssignal]

Hi all, could someone please show me the pads used to program the STM chip. I can't find a pic online. It's a kte-6sc board. Thanks

Normally the schematics were on the KT open source firmware wiki, but it's no longer there

02 Preparing the hardware

OSEC Open Source E-Bike Controller in a Windows toolchain for a STM8 - stancecoke/BMSBattery_S_controllers_firmware

github.com

Strange because it was there a year ago when I tinkered with this. Maybe because the corresponding bitbucket got deleted

Maybe browse through the beginning of this huge thread

KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

This OpenSource firmware/embedded software runs on the BMSBattery S/Kunteng KT motor controllers. The main advantages of this controllers are: 1. sine wave/"FOC": motors run silent and very efficient 2. cheap: starting at 20€ 3. widely available: many online shops sell them and ship to worldwide...

endless-sphere.com

Or perhaps someone remembers of the order of pins. But there are normally 4 holes in a row, I think power and ground might have been the first and the third but I am not too certain...

 

[stancecoke]

Maybe because the corresponding bitbucket got deleted

The photos can still be found in the German forum:

https://www.pedelecforum.de/wiki/do...eek:pen_source_firmware_vorbereitung_hardware

But the header is at different locations on different boards.

I got it all setup, but getting this error. Just incase anyone is reading I am using a LCD03. Getting the same errors with the Java tool

make: *** [ACAsetPoint.rel] Error 1

It looks like it couldn't compile. Idk why.

Approximately a year ago I tried the torque from X4 branch (superior to the master branch in speed and allegedly in lack of glitching) GitHub - stancecoke/BMSBattery_S_controllers_firmware at Torque_from_X4

And this branch which has updated and aggregated code and LCD8 support

GitHub - consp/BMSBattery_S_controllers_firmware: OSEC Open Source E-Bike Controller in a Windows toolchain for a STM8

OSEC Open Source E-Bike Controller in a Windows toolchain for a STM8 - consp/BMSBattery_S_controllers_firmware

github.com

Both compiled no problem. Perhaps double check that you followed all the software instructions correctly...

 

[basssignal]

Thanks Alex, i tried the X4 Branch but still experiencing issues. Attached the java setup.

adc.h:27: error 328: inline function adc_trigger declared with external linkage, but not defined in translation unit

I guess you have to delete the "inline" in this line of code.
The recent version of SDCC seems to be more strict in throwing warnings and errors...

You could try to use an older version of SDCC also.

Eureka! its compiling now. The issue appeared to be the SDCC version i was using. I installed v4.1.0 x64 and it didn't work, i then installed v4.1.0 RC1 and it compiles fine without errors and the hex uploads to the STM08 no problem now

The LCD03 switches on ok but no throttle or PAS. Its a sine KT36/48SVPR-GLT03.

36V battery (42V when charged), Bafang 250W motor, with 3 phase, 5 hall connected. External speed sensor installed. The original firmware worked ok but my aim was simply to get off-road and road compliant modes using the brake morse code.

My settings attached, Can anyone spot anything wrong in my config? Do i need to reset the LCD03 to factory default?

Using Stancecoke x4 build.

Thanks
