Can anyone explain why inputs to the Clarke transform are negated before being entered?
clarke1.As=-(_IQ15toIQ((AdcResult.ADCRESULT1<<3)-cal_offset_A)<<1);
clarke1.Bs=-(_IQ15toIQ((AdcResult.ADCRESULT2<<3)-cal_offset_B)<<1);
The orientation of the op-amp circuits looks similar to other kits, what is special here?
