[ARM] Reverse Direction for BLDC motor in SVPWM

[surendran_raj]

Hi.,
As I trying to code a BLDC controller in SVPWM method it worked but the problem i faced is it running in backward direction , i need it to run in forward direction. To run in forward direction i got an source from internet by changing the two Phase and hall sensor but i need without changing it's Phase and Hall sensor can anyone help me to solve it .

reference waveform

Phase1(yellow)
phase2(red) phase shift of 240
phase3(black) phase shift of 120

So you already know that changing two phases solves the problem.
Since you don´t want to change it in hadware ... what keeps you from doing the same in software?
