1.0. Connecting the System to a PC

page

Development System EasydsPIC6

Step 1:

Follow the instructions provided in the relevant manuals and install the dsPICash program and the USB driver from the product CD.
USB drivers are essential for the proper operation of the on-board programmer.
In case you already have one of the Mikroelektronika’s dsPIC compilers installed on your PC, there is no need to reinstall USB drivers
as they are already installed along with the compiler.

Step 2:

Use the USB cable to connect the EasydsPIC6 development system to a PC. One end of the USB cable, with a USB connector of
B type, should be connected to the development system, as shown in Figure 1-2, whereas the other end of the cable with a USB
connector of A type should be connected to a PC. When establishing a connection, make sure that jumper J7 is placed in the USB
position as shown in Figure 1-1.

Step 3:

Turn on your development system by setting the POWER SUPPLY switch to ON position. Two LEDs marked as POWER and USB
LINK will be automatically turned on indicating that your development system is ready to use. Use the on-board programmer and the
dsPICprog programmer and the dsPICash program to dump a hex code into the microcontroller and employ the system to test and
develop your projects.

NOTE: If some additional modules are used, such as LCD, GLCD etc, it is necessary to place them properly on the development

system while it is turned off. Otherwise, either can be permanently damaged. Refer to gure below for the proper placing of

the additional modules.

2.0. Supported Microcontrollers

The EasydsPIC6 development system provides six separate sockets for dsPIC microcontrollers in DIP40, DIP28 and DIP18 packages.
These sockets allow supported microcontrollers in dsDIP packages to be plugged directly into the development board. There are two
sockets for dsPIC microcontrollers in DIP40 package, three sockets for dsPIC microcontrollers in DIP28 package and one socket for
dsPIC microcontrollers in DIP18 package provided on the board. Which of these sockets will be used depends solely on the pinout of
the microcontroller in use. The EasydsPIC6 development system comes with the microcontroller in DIP40 package.

Figure 2-1: Microcontroller sockets

dsPIC microcontrollers normally use a quartz crystal for stabilizing clock frequency. The EasydsPIC6 provides two sockets for
quartz crystal. Microcontrollers in DIP40A, DIP40B and DIP28A packages use socket X1 (OSC1A, OSC1B) for quartz crystal. If
microcontrollers in DIP18, DOP28B and DIP28C packages are used, it is necessary to move quartz crystal from socket X1 to socket
X2 (OSC2A, OSC2B). Besides, it is possible to replace the existing quartz crystal with another one. The value of the quartz crystal
depends on the maximum clock frequency allowed.

Figure 2-2: Plugging microcontroller into appropriate socket

Prior to plugging the microcontroller into the appropriate socket, make sure that the power supply is turned off. Figure 2-2 shows how
to correctly plug a microcontroller. Figure 1 shows an unoccupied DIP40 socket. Place one end of the microcontroller into the socket
as shown in Figure 2. Then put the microcontroller slowly down until all the pins thereof match the socket as shown in Figure 3. Check
again that everything is placed correctly and press the microcontroller easily down until it is completely plugged into the socket as shown
in Figure 4.

NOTE: Only one microcontroller may be plugged into the development board at one time.

3.0. On-board dsPICprog Programmer

page

A programmer is a necessary tool when working with microcontrollers. It is used to load a hex code into the microcontroller and
provides an interface between the microcontroller and a PC. The EasydsPIC6 has an on-board dsPICprog programmer. All you need
is a .hex le to be loaded into the microcontroller using the dsPICFLASH program. Figure 3-3 shows connection between the compiler,
the dsPICFLASH program and the microcontroller.

Microcontroller pins for programming (PGD, PGC and MCLR) are not directly connected to the on-board programmer, but via a multiplexer.
The multiplexer is used to disconnect the microcontroller pins used for programming from the rest of the board while the programming
process is under way. As soon as the programming process starts, the multiplexer automatically disconnects pins for programming from
the development system. In this case, these pins cannot be used as I/O pins. When the programming process is complete, the multiplexer
reconnects these pins to the development system, after which they can be used as I/O pins.

During the programming, the multiplexer disconnects
the microcontroller pins used for programming
from the rest of the board and connects them to

the dsPICprog programmer. When the process
of programming is complete, these pins are
automatically disconnected from the programmer
and may be used as input/output pins.

4.0. mikroICD (In-Circuit Debugger)

page

The mikroICD (In-Circuit Debugger) is an integral part of the on-board programmer. It is used for testing and debugging programs in
real time. The process of testing and debugging is performed by monitoring the state of all registers within the microcontroller while
operating in real environment. The mikroICD software is integrated in all dsPIC compilers designed by Mikroelektronika (mikroBASIC
PRO, mikroC PRO, mikroPASCAL PRO etc). As soon as the mikroICD debugger starts up, a window called Watch Values, appears
on the screen, Figure 4-1. The mikroICD debugger communicates to the microcontroller through the microcontroller’s pins used for
programming.

Development System EasydsPIC6

mikroICD debugger options:

Start Debugger [F9]
Run/Pause Debugger [F6]
Stop Debugger [Ctrl+F2]
Step Into [F7]
Step Over [F8]
Step Out [Ctrl+F8]
Toggle Breakpoint [F5]
Show/Hide Breakpoints [Shift+F4]
Clear Breakpoints [Ctrl+Shift+F5]

Each of these commands is activated via
keyboard shortcuts or by clicking appropriate

icon within the Watch Values window.

The mikroICD debugger also offers functions such as running a program step by step (single stepping), pausing the program execution
to examine the state of currently active registers using breakpoints, tracking the values of some variables etc. The following example
illustrates a step-by-step program execution using the Step Over command.

Step 1:

In this example the 41st
program line is highlighted in
blue, which means that it will
be executed next. The current
state of all registers within the
microcontroller can be viewed
in the mikroICD Watch Values
window.

Step 2:

After the Step Over command
is executed, the microcontroller
will execute the 41st program
line. The next line to be
executed is highlighted in blue.
The state of registers being
changed by executing this
instruction may be viewed in
the Watch Values window.

NOTE: For more information on the mikroICD debugger refer to the mikroICD Debugger manual.

During operation, the program line to be executed next is
highlighted in blue, while the breakpoints are highlighted in
red. The Run command executes the program in real time
until it encounters a breakpoint.
