MikroElektronika
All Mikroelektronika’s development systems feature a large number of peripheral
modules expanding microcontroller’s range of application and making the
process of program testing easier. In addition to these modules, it is also
possible to use numerous additional modules linked to the development system
through the I/O port connectors. Some of these additional modules can operate
as stand-alone devices without being connected to the microcontroller.
mikroETH Additional Board
The
mikroETH
additional board is used to connect a microcontroller to Ethernet network.
mikroETH
is connected to the development
system via a proto board, but it can also be directly connected to the microcontroller provided in some device. The
mikroETH
board
features three connectors. Two male 1x5 connectors are used for connection with the proto board or a device, while the RJ45
connector is used for connection with Ethernet network.
Communication between the microcontroller and Ethernet network is established via the ENC28J60 ethernet controller provided on
the
mikroETH
board. This controller enables data to be transferred from Ethernet network to the microcontroller and vice versa using
serial SPI communication. In Figure 4, the
mikroETH
board is connected to the microcontroller via the SPI communication module
built into the microcontroller.
