Compared to the latest firmware(rev 14.0 or above), I found fimeware 12.0 is better suited for ESC Xrotor-20A(I used freq 24MHz), the motor runs more smoothly and is not that "violent" when startup. Also,in low pwm,the motor speed is lower than that of rev 14.X.
Specially when I used the ESC with pixhawk for my drone, after I unlock the RC, the motor will not stall and act very quickly when propeller is installed on motor.On the contrary, the rev 14.X may sometimes casue stratup failure.
I think the reason is the hardware of Xrotor-20A is not quite match the latest firmware.When I use rev 14.x on HW of Skywalker-40A, the motor will commutate correctly and will not stall. Please excuse my poor English :)

你好，你是哪位？xrotor20硬件是我设计的，不知有遇到什么问题？

你好，你是好盈的工作人员？是这样的，我分别使用BLHeli 14.0以上版本和12.0版本软件，发现14.0版本软件电机启动扭力比较大，而12.0比较平缓，而且在低油门段下12.0固件电机转速相对低一些。因此在快速从电机停止到拉高油门，或者说飞控解锁时候，当电机带桨时，14.0版本固件在xrotor-20A上面会引起电机无法正确换相，从而无法正常转动。而12.0版本固件就没这个问题。但是这两个固件在Skywalker-40A的硬件上面都不会有这个问题，所以我想14.0版本固件可能不是和xrotor-20A的硬件，特别是上面的mos专用驱动芯片很匹配。
Hi，you are a guy from hobbywing？Well，I used BLHeli 14.0 and 12.0 firmware separately on HW of Xrotor-20A and Skywalker-40A.The motor start power on 14.0 is greater than 12.0,and cause higher motor speed in low throttle range.When I pull throttle quickly from zero speed to 50% or above,the motor will stall on xrotor with 14.0 but not with 12.0.For Skywalker-40A,both firmware works fine,so I think firmware 14.0 is not quite suit for xrotor-20A,specially the mos driver IC on it.
