I just wanna share the new product "hovershoes".

I implemented open loop foc firmware on the EUC2 controller board(Not be tested). :mrgreen: Finally,i will implement foc firmware on the Lishui and JinHui and etc. https://github.com/KingQueenWong/BMC_FOC

I am very busy,but i will try my best to implement firmware to prove JinHui controller and ECU controller can do foc.

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.

I can not find MicroWorks 30B4 board or equivalent on taobao.

EUC1 controller(https://item.taobao.com/item.htm?spm=a1z09.2.0.0.2ed6e797zYFu2e&id=528731314428&_u=bm58rj4e4ba) and JinHui controller(https://world.taobao.com/item/544557726531.htm) both can do foc.

I have not a reflow soldering machine,i use a heat gun to solder it well. :D

Redesign low cost controller board for position control and speed control in my spare time,just my hobby :mrgreen:

My opinion: In low motor mechanical speed,the interpretation need to slow down; In high motor mechanical speed,the interpretation need to speed up;

The seller talk me that my test video is ok,because the controller is FOC controller which is controlled the phase current.High current mean high torque,low throttle mean low current,low current mean low speed.I compare to your EUC firmware,the LSW959-94F firmware can reach larger torque.The...
