Hello,
I wanted to ask if, meanwhile, there are some experiences with or further opinions on single shunt sensing and torque control like discussed here: Advice on Current Sensing for new board design - #28 by robin2906
Why? I have some generic chinese ebike controllers, and they all have the cheapest solution: stm32f103 clones + fast opamp + single shunt current sensing. I would love to create an open source firmware for these controllers using simple foc library because the delivered firmwares have their flaws.
I am aware of the complexity, but I fear the timing and delay tuning functionality a generic solution must provide to support different hardware.
