change setPwm function in FOCDriver to accept 3 args, with a default value for the 3rd Change stepper driver classes to use 3 arg setPwm, ignoring 3rd arg. created InlineCurrentSenseSync class in lib/currentsense. fixed timer bug in calibrate encoder, in main defined a label for serialusb, to make it easier to swap out.
Lemon Pepper Stepper Driver
Small, all in one hybrid stepper + BLDC driver, designed to mount to the back of NEMA 14/17 size stepper motors. The board supports up to 48V @ 1.5A with a choice of either step-dir, CAN bus, I2C, or USB inputs. The boards can easily be assembled by JLC and the design has been cost-optimized, coming in at about $20 per board fully assembled (minus connectors, which need to be modified to sit flat on motor back).
Due to the high pole pair count of stepper motors, a high resolution (21 bit) magnetic encoder is used, supporting both SPI and hardware ABI position encoding.
Despite the rather high theoretical performance of this board I think you would need some serious cooling to actually hit the potential 50-70W specs of the parts.
