What is PICEK?
+") is an old friend. It has een with us for 4 generations. Many of us made our first steps in em edded world with
+"). Today it has thousands of users: students, ho yists, enthusiasts and professionals. It is used in many schools
and other educational institutions across the glo e. We have sold them over ,--- in the world in the past 3 years. It
provides a $+ and .++ platform with common modules to ring you into the colorful em edded world.
+") has many common modules which allow you connect them to the microcontroller via wires y yourself. We
elieve that you will enjoy this free connection mode, ecause it will ring you the fun of creation.We now present you with
the new version +") that rings so much more, and we hope that you will e thrilled with your new oard, just as we
are. +")is a powerful PIC Development Board for 370+ Microchip PIC MCUs in DIP packaging. It features over 18
essential modules necessary in development. Board comes with /0122 y default and we provide over 500
samples in C language ased on PICC compiler for microcontrollers: /0122, /0112, /023, /04/2,
/13,5, /13,5- and /13,,-.In the future, we will write more samples for other PIC MCUs
Of course, we are not perfect and we asking ourselves what we can do to make such a oard even etter, and at the
same time, we are looking forward to receiving your valua le suggestions.

4Digit SEG ED Display
One seven segment digit consist of 7+1 LEDs which are arranged in a specific formation which can e used to represent
digits from 0 to 9 and even some letters. One additional LED is used for marking the decimal dot, in case you want to write
a decimal point in the desired segment. +") contains four of these digits put together to form 4digit segled display.
Driving such a display is done using multiplexing techniques. Data lines are shared etween segments, and therefore the
same segment LEDs in each digit are connected in parallel. Each digit has it’s unique digit select line, which is used to
ena le the digit to which the data is currently eing sent. By multiplexing data through all four segments fast enough, you
create an illusion that all four segments are in operation simultaneously. This is possi le ecause human eye has a slower
reaction time than the mention changes. This way you can represent num ers in decimal or hexadecimal form. Eight data
lines that are common for all the digits are connected to connector (0), and digit select lines are connected to
connector (=) via a 23(/=1 3to8 line decoder.The two connectors does not e connected to any IOs, and it makes
your experiments more flexi le. In order to ena le Segled Display,you must connect the =and 0 to the IO lines of
