communication
Ethernet is a popular computer networking
technology for local area networks (LAN).
Systems communicating over Ethernet
divide a stream of data into individual
packets called frames. Each frame contains
source and destination addresses and error-
checking data so that damaged data can be
detected and re-transmitted. EasyPIC PRO
™
v7 features standard RJ-45 connector which
enables microcontrollers that support Ethernet
communication to establish a connection with
a computer, router or other devices. All four
ethernet lines (TPOUT+, TPOUT-, TPIN+ and
TPIN-) are routed to the MCU card socket.
Only microcontrollers containing embedded
ethernet module soldered to 100-pin or 80-
pin TQFP Ethernet MCU cards can use these
lines and utilize ethernet connector. Additional
signalization LEDs are available on the board.
DATA BUS
Enabling Eth. LEDs
In order to enable ethernet LEDs,
you must enable SW5.5 (RA0) and
SW5.6 (RA1) DIP switches. This
connects the LEDA and LEDB lines
to appropriate microcontroller pins.
