3.2.2. 120˚ Trapezoidal Drive Support
The hardware supports both sensor and sensor-less 120˚ trapezoidal mode operation, but there is no sample code
supplied with the kit. However the motor included in the kit is fitted with Hall sensors and connector J9 is
provided for interfacing.
For sensor-less trapezoidal control the hardware supports BEMF detection by ADC and internal comparators.
The jumper configurations are shown in Table 3.
