MOTOR CONTROL STARTER
KIT USER’S GUIDE
Chapter 2. Software Description
The starter kit tutorial application demonstrates how to successfully integrate a noise
sensitive mTouch application within a standard Motor Control environment.
This chapter contains the following topics:
• Motor Control Application
• mTouch Capacitive Slider Application
• Integrating Motor Control and mTouch
2.1
MOTOR CONTROL APPLICATION
The motor control software and hardware on this starter kit are based on the algorithm
described in the application note, AN1160 “Sensorless BLDC Control with Back-EMF
Filtering Using a Majority Function”, which is available from the Microchip website
(www.microchip.com).
The main difference from the standard AN1160 software is the way the overcurrent fault
functionality is implemented. The dsPIC33FJ16MC102 DSC features an internal analog comparator, which allows instant detection of an overcurrent condition and immediate hardware shutdown of the PWM outputs. The overcurrent level can be easily set
in software, thus making the solution much more flexible and adaptable to a wide range
of motors.
The motor current that passes through a shunt, is amplified by an operational amplifier
and is available as input on an analog pin of the dsPIC33FJ16MC102 DSC. The analog
input can be configured in software both as a comparator input and as an ADC input.
Reading the current with the ADC module offers the possibility of implementing more
complex control algorithms, such as the single shunt.
To close the Fault detection loop, the comparator output is wired externally to the PWM
Fault input. As soon as the current exceeds the level set in software, the comparator
will toggle its output and the PWM will be shut down immediately, without waiting for
the next clock pulse to occur.
2.2
mTouch CAPACITIVE SLIDER APPLICATION
The capacitive slider on the Motor Control Starter Kit is implemented based on the
application note, AN1250 “Microchip CTMU for Capacitive Touch Applications”. For
detailed information on mTouch sliders and buttons, and the CTMU module, refer to
this document, which is available from the Microchip website (www.microhip.com).
A two-channel capacitive slider is implemented on the Motor Control Starter Kit. Each
channel is connected to an analog input on the dsPIC33FJ16MC102 DSC. The CTMU
module charges each channel’s capacitance with a fixed current for a certain amount
of time. The capacitance of each channel depends on the position of the user’s finger
over the slider, and it is at its higher value when the slider is not touched. After the fixed
charging time has elapsed, the CTMU module stops charging the capacitors and triggers the ADC to start sampling and converting the voltage on each capacitor to a
numerical value.
© 2011 Microchip Technology Inc.
DS75015A-page 15
Motor Control Starter Kit User’s Guide
The numerical value for each channel is filtered to remove noise, and then, based on
predefined thresholds, the position of the user’s finger on the slider is determined.
Movements over the slider can also be detected by monitoring both channels over a
period of time.
2.3
INTEGRATING MOTOR CONTROL AND mTouch
The dsPIC33FJ16MC102 DSC runs at a maximum of 16 MHz, and has sufficient
resources to run the Motor Control Starter Kit demonstration application, including the
motor control and the mTouch features.
Capacitive touch applications require a noise free environment, which is not the case
of motor control applications where MOSFETs turn on and off continuously, generating
noise spikes on the power supply levels. In such an environment, it is important to take
the capacitive slider measurements at a time when no MOSFETs are switching. This is
achieved by reducing the capacitance charging time to a minimum, by increasing the
charging current, and synchronizing it to the PWM cycle.
The ADC module of the dsPIC33FJ16MC102 DSC allows simultaneous sampling of
four different analog channels. Because three channels are needed for the BEMF feedback from the motor’s phases, one channel remains available for the CTMU module.
Both of the slider’s channels are sampled and converted alternatively on subsequent
PWM cycles, as shown in Figure 2-1.

The CTMU module uses a trigger to start and stop charging of the slider’s capacitors.
The trigger is configured in such a way that the ADC starts conversion a few nanoseconds after the capacitor has stopped charging. This ensures that no PWM switching
occurs while sampling the voltage on the capacitor.
However, avoiding the PWM switching events in the charging period is also important.
This is easily achieved in this configuration since the duty cycle is usually much larger
than the capacitor charging time. After the ADC completes converting all four channels,
three BEMF signals and one of the capacitors, the ADC interrupt is triggered and the
capacitor is discharged to allow charging another one in the next cycle.

The application side of the starter kit is centered on the dsPIC33FJ16MC102 DSC,
which requires very little additional hardware to perform its tasks. The Motor Control
Starter Kit is preprogrammed with an application featuring integrated motor control and
mTouch functionality. The motor control application algorithm is based on the
application note AN1160 “Sensorless BLDC Control with Back-EMF Filtering Using a
Majority Function”.

DS75015A-page 17
Motor Control Starter Kit User’s Guide
The powerful PWM module allows easy control over the 3-phase BLDC motor. The
PWM module features three complementary output pairs, hardware Fault shutdown,
programmable dead time, among others. A standard 3-phase inverter is used to
interface the device and the motor.
Three ADC channels provide information of the motor’s BEMF by reading the voltage
on the motor windings. Three resistor networks scale the voltage in the range needed
by the ADC module.
A single-shunt topology is featured on this starter kit, which can be used for overcurrent
protection or for a single-shunt control algorithm.
The dsPIC33FJ16MC102 DSC also features three analog comparators. One internal
comparator is used to trigger the Fault function of the PWM module if an overcurrent.
The advantage of the internal comparator is that different software thresholds can be
used to implement overcurrent conditions on different motors.
The demonstration application accepts user inputs from two sources: the capacitive
slider, and the push button (S1). The device’s CTMU module works together with the
A/D Converter to sample and convert both the channels of the capacitive slider. Three
user LEDs are also available for various display combinations.
The 9V power supply provided with the kit is sufficient for running the demonstration
application in Stand-alone mode. In Debug mode, both the 9V power supply and the
USB connection must be used.

PROGRAMMER/DEBUGGER
The Motor Control Starter Kit includes an on-board programmer/debugger circuit that
provides connectivity over USB. This circuit is hard-wired to the dsPIC device to
provide ICSP™ debugging/programming capability.

A 9V power supply powers the dsPIC33FJ16MC102 DSC
and the motor control circuitry on the starter kit. To operate
the starter kit, connect the power supply provided with the
starter kit (AC162039) to J3.
3-Phase Inverter
N/A
1-1
4
Microchip’s TC4428 dual MOSFET drivers provide the interface between the low-voltage control side, the
dsPIC33FJ16MC102 DSC, and the power side of the application (i.e., MOSFETs). These drivers provide the MOSFETs
with current as well as the proper voltage, inverting the
high-side PWM to drive the P-channel MOSFET, while keeping the delay time equal to the N-channel MOSFET.
The 3-phase inverter features three half-bridges implemented
with dual N- and P-Channel MOSFETs. While the MOSFETs
are capable of driving higher currents, the 10W power supply
limits the maximum current to approximately 800 mA. At this
power level, there is no need for an external heat sink.
BLDC Motor

A 3-phase BLDC motor is provided with the Motor Control
Starter Kit (Shinano DR-29312). The motor specifications are

BEMF Feedback
N/A
1-1
6
A six resistor network consisting in three voltage dividers is
connected to the motor windings to measure the BEMF of the
motor, providing the feedback needed for driving the motor in
sensorless mode. Based on the ADC measurements, the
motor virtual neutral point is reconstructed in software. The
resistor values are chosen taking into consideration the maximum BEMF voltage on the motor terminals and the maximum
voltage allowed on the ADC input pins.
Current Feedback
N/A

A single-shunt topology has been implemented on this starter
kit, featuring a 0.5Ω shunt. One MCP6021 operational amplifier provides the current input to the ADC channel at a resolution of 2.5V/A, with no offset. A 1.67V offset can be
configured by populating R60 and R62 with 10 KΩ resistors.
