USB Interface
The F1 LV Evaluation Platform includes a USB to serial interface. This provides the
capability to control the motors in real time without entering Debug mode. PC control
software communicates with the F1 LV Evaluation Platform software to create an inte-
grated motor control evaluation system. The PC software and interface driver are avail-
able for free download from the Microchip web site at

Add-on Board Power
When using an add-on board, the F1 LV Evaluation Platform power should be supplied
from the add-on board. The J6 jumper option makes this connection. There is no
jumper option to supply power to the add-on board from the F1 LV Evaluation Platform,
because most of the platform power options do not have sufficient capacity. When
power is applied to the F1 LV Evaluation Platform through the add-on board, then the
UNI/O
from the add-on board. The J6 jumper option makes this connection. There is no

memory is detected and read. The F1 LV Evaluation Platform software config-
ures itself to operate the motor identified in the memory. This automatic configuration
also applies to the PC control software.

Add-on Board Memory
Every add-on board, with one exception, includes a UNI/O memory device that con-
tains:
• board ID
• board revision
• parameters associated with the motor supplied with the add-on board
When the F1 LV Evaluation Platform senses that an add-on board is attached, the initial
display shows the motor type and add-on board revision. Motor speed can be con-
trolled with either the potentiometer on the F1 LV Evaluation Platform or with the PC
interface speed control. Additional motor capabilities are available through the PC con-
trol interface. These are described in more detail in the sections specific to each motor.
The first generation BLDC boards do not have a UNI/O memory. When the F1 LV
Evaluation Platform does not detect a UNI/O memory, it then checks voltages on other
selected J3 connections to determine if a BLDC circuit is present. When a BLDC board
without UNI/O memory is detected, the motor parameters are then retrieved from the
F1 LV Evaluation Platform EEPROM memory. The factory defaults for these parame-
ters match those needed for the motor originally supplied with the BLDC board. If the
parameters are modified for another motor, then the File->RAM->EEPROM option will
save those parameters to the F1 LV Evaluation Platform EEPROM memory in lieu of
the UNI/O memory.
The advantage that the UNI/O equipped boards have is that several different add-on
boards can each support and remember the settings for a different motor. Various
BLDC motors can be accommodated when working with the first generation BLCD
Add-on Board, by saving and recalling the motor parameters to and from the PC disc
storage with the File->Save… and File->Open… options.

PC SOFTWARE OVERVIEW
The F1LVDemo software is a Graphical User Interface (GUI) providing control of the
motor speed and direction. The GUI also provides access to key parameters of the
motor operation. The control parameters vary by motor type. Each parameter and
method of optimization are described in detail in the motor sections of this document.
