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

Ok, did some more testing and it seems to work consistent without changing the code above. Think i turned on the pass code feature when testing the parameters without realizing it.

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

Hi guys, it looks like I might have figured out the checksum issue with the kunteng lcd's. It would be great if some others with kunteng displays could second this before committing anything. The UART transmission from the display contains 14 words instead of the 13 that where in the code so I've up...

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

Anyone seen these controllers before (ZWSRLT series)? (its kt and says its sine and square with automatic changeover). Tested it, it works both with hall connected and without but no change in efficiency or current draw. The main chip they use is different (it only has 1824w4 written on it, no brand...

Re: Tsdz2 firmware open source adapted to vlcd5

It measures 2.5Ohms, so the wire is not broken. It might be shorted though; 2.5ohms looks fairly low at first glance but then I don't have any data on what it should be. To use the display for debugging I'm wondering if there is some flag that needs to be set before the display to show the data from...

Re: Tsdz2 firmware open source adapted to vlcd5

Thanks @vscope. I've tried uint16_t ui16_temp; ui16_temp = 505; ui8_tx_buffer[6] = (uint8_t) (ui16_temp & 0xFF); ui8_tx_buffer[7] = (uint8_t) (ui16_temp >> 8); but still no luck (0.00 on screen). There seems to be more to it but so far I don't fully understand how the function "calc_wheel_s...

Re: Tsdz2 firmware open source adapted to vlcd5

Also I could use some advice; when opening up the motor I might have put the pas sensor in wrong somehow and don't seem to get a signal anymore. I'm hoping to debug it by temporarily displaying the pass cadence on the vlcd6 instead of the bike speed but can't get it to work. Has anyone tried use the...

Re: Tsdz2 firmware open source adapted to vlcd5

Hi all, great job on the development . I'm new on this project but have programming experience and have been looking at the code for a few weeks now with a 48v tsdz2 with vlcd5 display and can confirm all the settings so far have been working well on the vlcd5 display. As for the backwards resistanc...

Re: pedal assist bypass no more available on Eu controller

Ok Rick,

The answer was so right in front of me, that I couldn't see it. By removing the jumper, the pas was disabled.

Thank you a lott.

Re: pedal assist bypass no more available on Eu controller

Rick,

I think that was a verry usefull reply, I never payed attention to that jumper, but a short cut jumper is indeed always suspisious and means that an open jumper will propably do something else. I am going to try it right away. Will let you now what it does.

Thanks,

Regards.

pedal assist bypass no more available on Eu controller

Due to law restrictions here in Belgium(and I supose in the rest of europe) the 48,36 and 24V 20A controllers from crystalyte come without the possibility of disabling the pedal assist system now. This means you always have to pedle before the controller starts. This is very inconvenient for testing...
