EasyPIC PRO
Headers Buttons
With enhanced connectivity as one of the key features
of EasyPIC PRO
headers for each PORT. I/O PORT group contains one
male IDC10 2x5 header (like CN22 Figure 6-3). There
is one more IDC10 header available on the right side
of the board, next to DIP switches. These headers are
all compatible with over 70 mikroElektronika accessory
boards, and enable simple connection.

connection with mikroElektronika accessory boards

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. This button is directly
connected to the microcontroller
MCLR pin.

(tri-state)
The logic state of all microcontroller
digital inputs may be changed using
push buttons. Tri-state DIP switch
SW13 is available for selecting
which logic state will be applied to
corresponding MCU pin when button is
pressed, for each I/O port separately.
If you, for example, place SW13.3 in
VCC position, then pressing of any
push button in PORTC I/O group will
apply logical one to the appropriate
microcontroller pin The same goes for
GND. If the DIP switch is in the middle
position, then all push buttons of the
associated PORT will be disconnected
LEDs
current value specified by the manufacturer. A common
LED diode voltage is approximately 2.5V, while the
current varies from 0.2mA to 20mA, depending on
the type of the LED. The EasyPIC PRO v7 board uses
low-current LEDs with typical current consumption of
0.2mA or 0.3mA, depending
of VCC voltage selection.
Board contains 69 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
SW6 (Figure 6-6).
