ARM®Cortex™-M4 are increasingly popular microcontrollers. They are rich
with modules, with high performance and low power consumption, so
creating a development board the size of EasyMx PRO™ v7 for Tiva™C
Series was really a challenge. We wanted to put as many peripherals
on the board as possible, to cover many internal modules. We have
gone through a process of ne tuning the board's performance,
and used 4-layer PCB to achieve maximum eciency. Finally, it
had met all of our expectations, and even exceeded some. We
present you the board which is powerful, well organized, with
on-board programmer and debugger and is ready to be your
strong ally in development.

EasyMx PROv7
Power supply
Board contains a switching power
supply that creates stable voltage
and current levels necessary
for powering each part of
the board. The power supply
section contains a specialized
MC34063A power regulator which
creates a VCC-3.3V power supply, thus
making the board capable of supporting 3.3V
microcontrollers. Power supply unit can be powered in
three dierent ways: with USB power supply (CN6), using
external adapters via adapter connector (CN34) or additional
screw terminals (CN35). External adapter voltage levels must be in
range of 9-32V DC and 7-23V AC. Use jumper J1 to specify which power
source you are using. Upon providing the power using either external adapters
or a USB power source you can turn on the power supply by using SWITCH 1 (Figure
3-1). Power LED ON (Green) will indicate the presence of power supply. Figure 3-1: Power supply unit of

Before you plug the microcontroller card into
the socket, make sure that the power supply is
turned o. Images below show how to correctly
plug in the card. First make sure that the MCU
card orientation matches the silkscreen outline
on the EasyMx PRO™v7 Tiva™C Series board MCU
socket. Hold the MCU card over the socket, so
each header is properly aligned with the socket,
as shown in Figure 4-4. Then put the MCU card
slowly down until all the pins slide into the socket.
Check again if everything is placed correctly and
press the MCU card until it is completely plugged
into the socket as shown in Figure 4-5. If done
correctly all pins should be fully inserted. Only now
you can turn on the power supply.

Building on more than 20 years of experience developing leading microcontroller technology and ARM®-based processors, Texas Instruments launched the
Tiva™ARM® MCU platform in 2013, with Tiva™C Series TM4C123x ARM Cortex-M4 MCUs.
These are the rst Cortex-M-based MCUs to be built on 65 nanometer ash process technology, setting the roadmap to higher speeds, larger memory and
lower power. The Tiva™C Series TM4C123x MCUs are ideal for home, building and industrial automation.
The ARM Cortex-M4 oating-point core Tiva™C Series MCUs strike a perfect balance between performance and power consumption. They eliminate performance
tradeos with 12-bit ADC accuracy, achievable at the full 1 MSPS rating without any hardware averaging. And with low-power standby currents as low as
1.6 uA, they enable longer battery life and support constrained power budgets.

Hardware debugger
What is debugging?
Every developer comes to a point when it's necessary to
monitor code execution in order to nd errors in the code, or
simply to see if everything is going as planned. This hunt for
bugs or errors in the code is called debugging. There are two
ways to do this: one is software simulation, which enables
you to simulate what is supposed to be happening on the
microcontroller as your code lines are executed, and the other,
more reliable one, is monitoring the code execution on the
chip itself. And this latter one is called hardware debugging.
"Hardware" means that it is the real deal - code executes
right on the target device.
What is a hardware debugger?
The on-board mikroProg™programmer supports hardware
debugger - a highly eective tool for Real-Time debugging
on hardware level. The debugger enables you to execute
your program on the host Tiva™C Series microcontroller and
view variable values, Special Function Registers (SFR), RAM,
CODE and EEPROM memory along with the code execution on
hardware. Whether you are a beginner or a professional, this
powerful tool, with an intuitive interface and a convenient
set of commands will enable you to track down bugs quickly.
mikroProg debugger is one of the fastest, and most reliable
debugging tools on the market.
Supported compilers
All MikroElektronika compilers, mikroC™, mikroBasic™and
mikroPascal™for ARM®, natively support mikroProg™for
Tiva™C Series, as well as other compilers, including KEIL®,
IAR®. Specialized DLL module allows compilers to exploit
the full potential of fast hardware debugging. Along with
compilers, make sure to install the appropriate programmer
drivers and mikroProg Suite™for ARM®programming
software, as described on pages 14 and 15.
When you build your project for debugging, and program the microcontroller with this HEX le, you
can start the debugger using [F9] command. The compiler layout will switch to Debugging View,
and a blue line will mark where code execution is currently paused. Use the debugging toolbar in
the Watch Window to guide the program execution, and stop anytime. Add the desired variables
to the Watch Window and monitor their values.
How do I use the debugger?

Start Debugger [F9] Starts Debugger.
Run/Pause Debugger [F6] Run/Pause Debugger.
Stop Debugger [Ctrl + F2] Stops Debugger.
Step Into [F7]
Executes the current program line, then halts. If the executed
program line calls another routine, the debugger steps into the
routine and halts after executing the rst instruction within it.
Step Over [F8]

One of the most distinctive features of EasyMx PRO™
v7 for Tiva™C Series are its Input/Output PORT groups.
They add so much to the connectivity potential of the board.
Everything is grouped together
PORT headers, PORT buttons and PORT LEDs are next to each other and
grouped together. This layout givest the EasyMX PRO for Tiva™C Series a
clean, well organized look and it makes development easier. We have also provided
additional PORT headers on the right side of the board, so you can access any pin
you want from that side of the board too.

up/down DIP switch, buttons and LEDs all in one place

Figure 6-3: Schematic of the single I/O group connected to microcontroller PORTE
Tri-state pull-up/down DIP switches
Tri-state DIP switches, like SW7 on Figure 6-2, are used to
enable 4K7 pull-up or pull-down resistor on any desired port pin.
Each of these switches has three states:
1. middle position disables both pull-up and pull-down feature
from the PORT pin
2. up position connects the resistor in pull-up state to the
selected pin
3. down position connects the resistor in pull-down state to the
selected PORT pin.

Headers Buttons LEDs
LED (Light-Emit-
ting Diode) is a
highly ecient
electronic light
source. When con-
necting LEDs, it is
necessary to place
a current limiting
resistor in series so
that LEDs are pro-
vided with the current value specied by the manu-
facturer. The current varies from 0.2mA to 20mA,
depending on the type of LED and the manufacturer.
The EasyMx PRO™v7 for Tiva™C Series board uses
low-current LEDs with typical current consumption of
0.2mA or 0.3mA. Board
contains 67 LEDs which
can be used for visual in-
dication of the logic state
on PORT pins. An active
LED indicates that a logic
high (1) is present on the
pin. In order to enable
PORT LEDs, it is neces-
sary to enable the corre-
sponding DIP switch on
SW12 (Figure 6-6).
Figure 6-6: SW12.1
through SW12.8
switches are used to
enable PORT LEDs
The logic state of
all microcontroller
digital inputs may be
changed using push
buttons. Tri-state
DIP switch SW8 is
available for select-
ing which logic state
will be applied to corresponding MCU pin when but-
ton is pressed, for each I/O port separately. If you, for
example, place SW8.5 in VCC position, then pressing
of any push button in PORTE I/O group will apply logic
one to the appropriate microcontroller pin. The same
goes for GND. If DIP switch is in the middle position
neither of two logic states will be applied to the ap-
propriate microcontroller pin. You can disable pin pro-
tection 220ohm resistors by placing jumpers J6 and
J7, which will connect your push buttons directly to
VCC or GND. Be aware that by doing so you may ac-
cidentally damage MCU in case of wrong usage.
Reset button
In the far upper right section of the
board, there is a RESET button, which
can be used to manually reset the mi-
crocontroller.
Figure 6-5: Button press
level DIP switch (tri-state)
Enhanced connectivity is one of the key features of
EasyMx PRO™v7 for Tiva™C Series. That's why we have
provided two connection headers for each PORT.
I/O PORT group contains one IDC10 header (like CN18
Figure 6-3). There is one more IDC10 header available
on the right side of the board, next to DIP switches (like
CN19 on Figure 6-3). These headers can be used to
connect accessory boards with IDC10 sockets.

mikroBUS™sockets
mikroBUS™pinout explained
Easier connectivity and simple conguration
are imperative in modern electronic devices.
Success of the USB standard comes from its
simplicity of usage and high and reliable data
transfer rates. As we in MikroElektronika see it,
plug-and-play devices with minimum settings
are the future in the embedded world too. That
is why our engineers came up with a simple,
but brilliant pinout with lines that most of
today’s accessory boards require, which almost
completely eliminates the need for additional
hardware settings. We called this new standard
the mikroBUS™.EasyMx PRO™v7 for Tiva™C
Series supports mikroBUS™with two on-board
sockets. As you can see, there are no additional
DIP switches, or jumper selections. Everything
is already routed to the most appropriate pins
of the microcontroller sockets.
mikroBUS™host connector
Each mikroBUS™host connector consists of two
1x8 female headers containing pins that are
most likely to be used in the target accessory
board. There are three groups of communication
pins: SPI, UART and I2Ccommunication. There
are also single pins for PWM, Interrupt,
Analog input, Reset and Chip Select. Pinout
contains two power groups: +5V and GND on
one header and +3.3V and GND on the other
1x8 header.
