1 Graphical User Interface description
The STSW-L9907-H GUI includes the fields highlighted in Figure 1:
Figure 1. STSW-L9907-H Graphical User Interface (GUI) for EVAL-L9907-H
1. Com Port Setup: this menu allows to set the COM port
2. SDI: this menu allows to select and to configure each device register. It is possible to
program all the bits of each register.
3. SDO: the value of each register is copied in the field of this menu. This portion of the
GUI allows to monitor the device status.
4. SPI Send/Receive: in this portion of the GUI it is possible:
a) To end an SPI commands or configuration as programmed in the SDI menu (see
#2) by pressing the “SEND” button.
b) To send a single SPI command manually written in the MOSI field (HEX format). In
the same time it is available to read the register value in the MISO filed.
c) SPI functionality: the LEDs, SPI SEND OK and SPI RECEIVE OK provide a
visual feedback about the SPI communication status (if the LEDs are on means
communication is working properly).
5. PWM signals: the Frequency and the Duty cycle of the each PWM signals are
programmed in this frame. The "START" button enables the PWM signal generators
(PWM signals: L1, L2, L3, H1, H2 and H3), whereas “STOP” button stops the the PWM

signals. Before sending a PWM configuration, the selected Frequency must be
confirmed by pushing the “SET” button.
6. ENABLE SETUP – BST_DIS SETUP & FS_FLAG STATUS: this frame is used is to
configure the EN1, EN2 and BST_DIS pins of the L9907 and to read the FS_FLAG
status.
7. ADC READ: this section displays the value of the Ib1 and Ib2 pins (ADC inputs).
8. MOTOR CONTROL: this menu is used to start a BLDC Motor Control based on Closed
Loop and by using 6-Steps Algorithm technique, to setup some parameters and to view
some useful waveforms:
a) Motor Parameters: through this menu it is possible to setup some parameters of
the BLDC Motor, such as “Polar Couples”, minimum and maximum rotation speed.
b) Closed Loop Tuning: through this menu it is possible to setup the PI parameters
for Closed Loop and Kp and Ki values.
c) Graphics Display: with this button it is possible to select a graphic between
Speed, Error, Duty, ADC IB1 and ADC IB2.
d) Speed Ref.: by using this cursor it is possible to set the target BLDC motor speed.
e) Single Read: this button allows to read the instantaneous speed value.
f) Duty %: it shows the value of the current Duty Cycle.
g) Graph ON/OFF: the button allows to turn ON and OFF the Graph window.
9. Automatic Reset: through this two buttons it is possible to automatically reset the
device at Start-up for Vcc=3,3 V and Vcc=5 V. Pressing the button “Automatic Reset
3.3 V”, the procedure described at Par. 3 point A will be automatically performed.
Pressing the button “Automatic Reset 5 V”, the procedure described at Par. 3 point B
will be automatically performed.
10. HELP: through this menu it is possible to download the SW help, the L9907 Datasheet
and info about the HW.

2 How to use the GUI to configure and test the EVAL-
L9907-H
The following procedure has to be followed to start the EVAL-L9907-H Device using the
L9907-H GUI.
A. Start up at Vcc= 3.3 V
1. Configure the COM port
2. Press “OK” button
3. Send the SPI frame 0xC800 (0b 1100100000000000) - DIAG & 0xE000 (0b– DIAG2
4. In the field #3 (see Section 1) it is possible to read the device answer in bit, in the field
n° 4 it is possible to read the SDI and SDO signals expressed in hex.
5. Check the FS_FLAG status (field #6). The value must be 01
B. Start up at Vcc= 5 V
The Power Up default value for Vcc over voltage threshold is “10”, corresponding to
Vcc=3.3 V application. The below procedure has to be followed in order to use Vcc=5 V (for
more details see the EVAL-L9907-H HW Manual):
1. Configure the COM port
2. Press “OK” button”
3. In field #7, force one of the EN pins to 0
4. Send the command 0x2401 (0b 0010010000000001) – CMD1 register in order to reset
the fault.
5. Press “SEND” in the field #4. If the communication has been established and the
command has been sent and interpreted properly, the LED “SPI SEND OK” will be
turned on. The LED “SPI RECEIVE OK” will be turned on if the device answer has
been received properly.
6. The field #3 will be updated with the device registers value as well as in the field #4 the
SDI and SDO expressed in hex
7. Send the SPI frame 0xC800 (0b 1100100000000000) - DIAG & 0xE000
(0b1110000000000000) – DIAG2
8. Set High the EN pin previously set to zero (step 3).
9. Check the FS_FLAG status (field #6): the value should be 01
C. How to start the PWM independently
1. Set the desired channel (L1, L2, L3, H1, H2 and H3) – Field #5
2. Insert the frequency value in the field #5.
3. Press “SET”.
4. Set Duty Cycle value.
5. Press “START”, to enable the PWM signals
6. In the field #5, press “STOP PWM” to stop the PWM signals.
7. Press the button “STOP” on the top side of the GUI to stop the execution of Labview
code and close the window.

D. How to start the MOTOR CONTROLL
1. STOP all the PWM signals by pressing “STOP PWM” for all 6 channels (L1, L2, L3, H1,
H2 and H3), see Field #5. This action will stop all PWM signals from L9907-H.
2. Follow the procedure described at point A or B or press one of the two button
“Automatic Reset 3.3 V” or “Automatic Reset 3.3 V” depending on the Vcc supply
value.
3. Setup the BLDC motor parameters (polar couples, min and max speed)
4. Set Kp and Ki values (for example by using a for a 60W BLDC motor set Kp= 10 and
Ki=5)(a)
5. Press “Start/Stop Motor” button and the motor will start to run. If the Motor shaft doesn’t
turn it means a fault is present. Stop the Motor Control and reset the fault following the
procedure at section A, point 3 to 5. Restart the motor control(b).
6. Set the rotation direction: Clockwise or CounterClockwise
7. Press “Start/Stop Motor” to stop the Motor shaft.
8. Press the button “STOP” on the top side of the GUI to stop the execution of Labview
code and close the window.
a. The Kp and Ki constants depend on the BLDC motor characteristics and must be tuned to achieve the best
control
b. Due to the Start-up procedure developed in the Firmware, depending on the BLDC motor and the BLDC rotor
position, a cross conduction between high-side and low-side Power MOSFET could happen; under this working
a fault is detected.

4 SPC560P-DISP: USB drivers installation
The GUI needs a dedicated USB driver to enable the serial communication channel. If the
driver is not yet installed or not appropriately configured, the following procedure describes
how to install the Driver or to update the current version.
To install the drivers the board SPC560P-DISP does not need the external supplier; the
USB connection provides the supply voltage.
1. Disconnect the USB from SPC560P-Discovery
2. If the UDE Visual Platform 4.2 is already installed as well as the drivers are updated go
to step #7 otherwise continue to next step
3. Download the SPC5-UDE/STK 4.02.07 from pls-mc web site.
4. Install the SW; right click on the icon named “ude-4-02-07-spc5-udestk.exe” then select
“Run as Administrator”
