    Math and Motor Control Library. The MMCL is based on the Cypress Cortex-M3 microcontrollers, all of the modules in the MMCL are used in the sample project that will be described in detail in this guide. You can use this sample project to control the low voltage PMSM or BLDC.
  • Page 5 Demo System Figure 1-2. Hall Signal Line Connection Hall port Note: If there are only 2 hall signals on the motor, the hall A and B line can be only connected to the inverter’s Hall A and Hall B port. Don’t connect on the Hall C port on the board. VCC and GND must be connected rightly, otherwise the hall won’t work right and the motor will also not run.
  • Page 6 Demo System Figure 1-4. JTAG Line Connection J-Link(SWD) Note: There is no isolator between the J-link and the HW, it is recommended to unplug the AC power and use the battery of your note book. Connect DC power 24V to Inverter board, shown as below. The DC voltage can be from 24~48V according to the rated voltage of the motor and the current of the board must be lower than 2A.

    Demo System 1.3 Run the Motor This section introduces how to the make the motor running as the setting parameter. 1.3.1 Motor Start/Stop When the parameters for the firmware and hardware are correctly set, the motor can be started for the normal running. You can follow the steps to run to motor.
