Not yet. I ordered the wrong resistor array before, so I wouldn’t have been able to test current sense. This is a very low-priority project so I waited until I was ordering other stuff rather than paying shipping again just for that.
But even if everything works, I’ll have to edit the PCB again or change the name, since it turns out it won’t work with SimpleFOC’s stepper modulation scheme. I assumed you’d want each coil to have one end positive and the other end negative at any given time (complementary PWM), but SimpleFOC sets one end negative and PWM’s the other end. That needs four different channels, not complementary pairs like I have. It should work fine with custom code, but according to Backflip, the existing scheme is better, so we shouldn’t add the code for mine into the main library.
It should work fine for 3-phase BLDC without any library modification, so that’s good for my 2204 extruder project. Speaking of which, how did your extruder turn out, @midelic_m?
