求助ESC32限流校准问题

dawanpi

在进行ESC32限流校准的时候出现问题，用的是坛友沈家兴那里买到的板子，自己买零件焊的ESC32，除了那个取样电阻是淘宝买的外，其余零件来自嘉立创和element14，质量应该没问题。
现在的情况是校准时会出现转速增加但是电流不变的情况，而且是刚开始转速低的时候正常，后来转速高了就不行了，电流先是一个固定值，1A多一点，然后全变成0了。我用的取样电阻是1毫欧的，并且在参数里面把默认的0.5毫欧改成1毫欧了，刷的固件版本是1.4.3，最新的2.0也有类似状况。附上log：

补充一下，电压转速校准的时候偶尔会出现电压和电流都为0的情况：

1. $ ./esc32Cal --r2v -p /dev/tty.usbserial-A601XMZA -a 15
   
2. Starting...
   
3. Reducing RPM...

这是电机还是运转状态的，转速也在一直增加。
