EasyMx PRO
Headers Buttons
With enhanced connectivity as one of the key features
of EasyMx PRO
connection headers for each PORT. I/O PORT group
contains one male IDC10 header (like CN24 Figure
6-3). There is one more IDC10 header available on
the right side of the board, next to DIP switches (like
CN33 on Figure 6-3). These headers can be used to
connect accessory boards with IDC10 female sockets.

connection with mikroElektronika accessory boards

be applied to corresponding MCU pin when button is
pressed, for each I/O port separately. If you, for example,
place SW16.5 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 appropriate microcontroller
pin. You can disable pin protection 220ohm resistors by
placing jumpers J6 and J7, which will connect your push
buttons directly to VCC or GND. Be aware that doing
so you may accidentally 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
microcontroller.

specified by the manufacturer. The current varies from
0.2mA to 20mA, depending on the type of the LED and
the manufacturer. The EasyMx PRO
board uses low-current LEDs with typical current
consumption of 0.2mA or
0.3mA. Board contains 72
LEDs which can be used
for visual indication 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 necessary
to enable the corresponding
DIP switch on SW15 (Figure
6-6).
