Re: OpenSource firmware BMSBattery S/Kunteng KT controllers
I implemented open loop foc firmware on the EUC2 controller board(Not be tested) That's great, I'm looking foreward to see your motor run with this firmware. You use DMA for ADC reading, that should be much faster. But I think that doesn't work with a STM8. Wich toolchain do you use with the STM32?...

Re: OpenSource firmware BMSBattery S/Kunteng KT controllers
I'm serious. EUC1 controller could do FOC,you can use Pin PB6 and Pin PB7 to printf somthing information(PB6 and PB7 is used for MPU6050,).The SHUNT is use the MOSFET internal resisitor. Maybe implementing software UART using LED pins... I would like to play and try implement the angle observer tha...

OK, fine that your start up is running now.

LD-LS13-F and LD-LS11-f is so cool. There are some things I don't like much: - the controllers seems to be available on 250W or 500W only -- the power resistors to measure phase currents should impose a limitation - not sure if there is a 48V version as I can't find it on online shops - no hall sen...

Temperature VS RDS(ON)/DCR As the temperature rises, the RDS does not rise too much. This feature can help us to sense current well.If you choose a good mosfet and good heat sink,maybe the temperature impact the RDS very little.Maybe something compensation need to be added,which may casue better pe...
