LDOs
CSPM3002 has 7 programmable LDO’s all of which can be measured using the on board ADC, using the measure
button on the LDO tab.
The LDO’s can also be loaded using on board resistors using the Load button beside the corresponding LDO names.
Figure IV-3: LDO voltage and loads
Fuel Gauge
CSPM3002 has an inbuilt Coulomb counter and ADC to measure Battery Voltage and temperature. Cirel Systems has
developed an algorithm for predicting remaining capacity/ Depth of Discharge of the battery. This algorithm can
reside in System/Apps processor. In CSPM3002-EVB this algorithm is residing in a microcontroller
To enable the use of Fuel Gauge, the user has to click the INITIALIZE FUEL GAUGE button. This initializes the fuel
gauge algorithm which is implemented in the microcontroller on the Applications board. To keep running the fuel
gauge algorithm, click on the UPDATE FG button.
The algorithm has flexibility to update the battery capacity on the fly.

Note: Do not disconnect the applications board with the fuel gauge running to avoid run time errors.
Backlight (WLED) and USB Boost
CSPM3002 sports two DCDC Boost converters, one for the Backlight white LED and one for the USB OTG and HDMI
power rail requirements.
WLED Boost
CSPM3002 has an integrated backlight driver with PWM dimming, current matching and supports a wide range of
output voltages up-to 24V (6 LEDs in series). It supports various fault detection features. The backlight is mimicked
by the use of 90 angle mounted LED’s on the leading edge of the applications board. These can be turned on using
the Green button under the WLED heading. The dimming can be controlled by the WLED Current drop down menu.
Figure IV-5: WLED and USB Boost
Important: It is always mandatory to connected Battery (VBAT-p) supply before the use of Backlight since the power
supply for the backlight is taken directly from battery.
Note: It is recommended to set the WLED Current to lower values to prevent visual discomfort while turn on.
USB Boost
The USB Boost is a fixed 5V boost converter which uses Battery supply which varies between 3.0V-4.2V to a fixed
5.0V output that can support loads of up to 700mA. The USB Boost can be turned on using the Green button under
the USB Boost heading. The measured output of USB Boost can be seen in the Bucks tab using the measure function
of the GUI.
Important: It is always mandatory to connected Battery (VBAT-p) supply before the use of Backlight since the
power supply for the backlight is taken directly from battery.
Note: It is recommended to power down both Backlight and USB Boost before the removal of battery supply from the
board.

IX. Troubleshoot
The commonly faced issues are stated below, if the issue is not seen in this section please contact us.
1.
GUI prompting “APPS BOARD NOT DETECTED”
GUI prompting Board not detected is when the device drivers are not installed correctly on the system.
Please refer Chapter III. for detailed steps on how to install the drivers.
2.
Device state reads boot up and LEDs are blinking at a low frequency
Please go to the Controls tab, turn on the ENABLE button, if it is already on, please turn off and turn on
again.
3.
Device manager shows an unknown device
Unknown device is shown because device drivers are not installed, please unplug the board and follow the
steps given in Chapter III. to correctly install the driver. Try connecting the EVB to an alternative port.
Also there should be a RED indicator LED which glows once the board is connected to the computer. If the
RED LED does not glow please check the “Board settings section” in Chapter III. to ascertain if the board
setting are correct.
4.
GUI Looks staggered or unarranged
The GUI looking staggered or unarranged is due to the text size being bigger on windows, to rectify this
right click on your desktop(Win7/8/8.1) and select Screen Resolution, in the Screen Resolution window
click on the Make text and other items larger or smaller link and select Smaller-100% option.
