2.2 Hardware Setup
The hardware required to run a motor is the MCT8315ZEVM, a micro-USB cable, and a power supply with a DC
output from 4.5 V to 35 V. Follow these steps to start up the MCT8315ZEVM:
1. Connect the DC power supply to header J7. Connect to VBAT and PGND to apply reverse polarity protection
and the Pi filter to the EVM. Otherwise, connect to VM and PGND to bypass the reverse polarity protection
and Pi filter.
2. If using the MCT8315ZH or MCT8315ZT, populate the desired resistor settings in the "HW Variant Resistors"
silk screen box, see
Table
silk screen box.
3. Apply user-configurable jumper settings. See the
4. Flash the program into the MCU as described in
disconnect the 4-pin JTAG connections.
5. Connect a micro-USB cable to the MCT8315ZEVM and computer.
6. Turn on the power supply and power up the PCB.
If using the MCT8315ZEVM with an external microcontroller, remove all shunt jumpers from jumper bridge J6.
Connect with external jumpers to the left side of the jumper bridge from the external MCU.
2.3 Hardware Connections Overview
Figure 2-2
shows the major blocks of the MCT8315ZEVM. The MCT8315ZEVM is designed for an input
supply from 4.5 V to 35 V and offers reverse-polarity protection and a Pi filter. The MCT8315ZEVM can
support all variants of the MCT8315Z device with locations for Hardware resistors, SPI resistors, and buck
components. Through the use of configurable shunts the MCT8315ZEVM can support many types of Hall
sensor configurations. For interfacing with the MCT8315Z GUI the MCT8315ZEVM has a FTDI chip to support
USB-to-UART and a MSP430.
