Introduction to clicker 2 for FT90x
Clicker 2 for FT90x is a
compact dev. kit with two
mikroBUS™sockets for click™
board connectivity. You can
use it to quickly build your
own gadgets with unique
functionalities and features.
It carries the FT900, a 32-bit
FT32 core microcontroller, two
indication LEDs, two general
purpose buttons, a reset
button, an on/o switch, a
li-polymer battery connector,
a USB Mini-B connector and
two mikroBUS™ socket. A
mikroProg connector and a
2x26 pinout for interfacing
with external electronics are
also provided. The mikroBUS™
connector consists of two
1x8 female headers with SPI,
I2C, UART, RST, PWM, Analog
and Interrupt lines as well as
3.3V, 5V and GND power lines.
Clicker 2 for FT90x board can
be powered over a USB cable.

1. Power supply
You can supply power to the board with a Mini-B USB cable provided
in the package. On-board voltage regulators provide the appropriate
voltage levels to each component on the board. Power LED (GREEN)
will indicate the presence of power supply.
You can also power the board using a Li-Polymer battery, via
on-board battery connector. On-board battery charger circuit
enables you to charge the battery over USB connection. LED
diode (RED) will indicate when battery is charging. Charging
current is ~300mA and charging voltage is 4.2V DC.
Battery power supplyUSB power supply
Figure 1-1:
Connecting USB power supply
Figure 1-2: Connecting
Li-Polymer battery
click™boards that use a 3.3V power supply can draw up to 750 mA of current, which is more current than a USB can supply (500 mA);
In those cases you would need to use the battery as the power supply, or the vsys pin on the side of the board.

3.1 Programming with mikroBootloader
You can program the microcontroller with a
bootloader which is preprogrammed by default.
To transfer .hex le from a PC to MCU you need
bootloader software (mikroBootloader USB HID)
which can be downloaded from:
www.mikroe.com/downloads/get/2230/
clicker_2_ft90x_bootloader.zip
After the mikroBootloader software is downloaded,
unzip it to desired location and start it.
Figure 3-2: USB HID mikroBootloader window
step 1 – Connecting clicker 2 for FT90x
To start, connect the USB cable, or if already connected press the Reset button
on your clicker 2 for FT90x. Click the Connect button within 5s to enter the
bootloader mode, otherwise existing microcontroller program will execute.

The microcontroller can be
programmed with external
mikroProg™for FT90x
programmer and mikroProg
Suite™ for FT90x®software.
The external programmer is
connected to the development
system via 2x5 connector
Figure 3-9. mikroProg™is a
fast USB 2.0 programmer with
hardware debugger support.
It supports all FT90x devices
in a single programmer.
Outstanding performance,
easy operation and elegant
design are its key features.

A standalone programming software utility called mikroProg Suite™for FT90x is available as an
alternative to programming the MCU directly from the FT90x compiler. This software is used for
programming of all supported FT90x microcontrollers. The software has an intuitive interface and
SingleClick™ programming technology. To begin, rst locate the installation archive on our web site:
www.mikroe.com/downloads/get/2215/mikroprog_suite_ft90x_v100.zip
After downloading, extract the package and double click the executable setup le, to start the installation.

Before attaching
the programming
connector, you
have to solder
the provided 2x5
male header to the
connection pads.

NOTE

Figure 4-1:
Two LEDs, two buttons
and a reset button
The board also contains a 1reset
button and a pair of 2buttons and 3
LEDs, as well as an ON/OFF switch.
The Reset button is used to
manually reset the
microcontroller — it
generates a low
voltage level on the
microcontroller’s reset
pin. LEDs can be used for visual
indication of the logic state on
two pins (P34 and P18). An active
LED indicates that a logic high (1) is
present on the pin. Pressing any of the two
buttons can change the logic state of the
microcontroller pins (P35 and P2) from
logic high (1) to logic low (0). In addition to
the onboard ON/OFF switch, two pins allow
you to connect your own external switch
(located beneath the switch).
