With internet in mind, one can think about many applications, below a few applications are listed: Figure 5 below shows our board setup: Curiosity development board with ETH Click connected to router.įigure 5: Curiosity development board with ETH Click connected to router Board is designed to use 3.3V power supply only. On-board crystal oscillator ensures stable operation. It features ENC28J60 and contains standard RJ-45 connector, transmit, receive and power LEDs. The ETH Click is an accessory board in mikroBus™ form factor.

The ETH Click board can also be used with any development board with mikroBus like the Curiosity Development board.

#MPLAB XC8 OPTIMIZATION SERIAL#

This board is equipped with an EC28J60 Ethernet controller chip, a 74HCT245 voltage translation chip, three LEDs, a 5 to 3.3 voltage regulator and an RJ45 connector with an integrated transformer.įigure 4: Connecting the Serial Ethernet Board to EasyPIC7 V7 development board This is a small board that plugs in directly to PORTC of the EasyPI CV7 development board via a 10-way IDC plug simplifying the development of embedded Ethernet projects. Figure 4 belows shows the the mikroElektronika Serial Ethernet Board.

To make the design of Ethernet applications easy, there are ready made boards that include the EC28J60 controller, voltage translation chip and an RJ45 connector. Figure 3 below shows how the ENC28J60 Ethernet controller can be interfaced to a PIC Microcontroller.įigure 3: ENC28J60 Ethernet Controller Connections The Ethernet controller chip operates at 3.3V, its output SO pin cannot drive the microcontroller input pin without a voltage translator if the microcontroller is operated at 5V. The interface between the microcontroller and the Ethernet chip is based on the SPI bus protocol, The SI, SO, and SCK pins of the Ethernet chip are connected to SPI pins ( SDO, SDI and SCLK) of the microcontroller. The figures below show ENC28J60 package types More information can be obtained from the ENC28J60 datasheet. Temperature Range: -40☌ to +85☌ Industrial, 0☌ to +70☌ Commercial (SSOP only).

Operating Voltage of 3.1V to 3.6V (3.3V typical).

With a small foot print package size the ENC28J60 minimizes complexity, board space and cost.įigure 1: Controlling devices from the internet The ENC28J60 is a popular 28-pin serial Ethernet chip, 10BASE-T stand alone Ethernet Controller with SPI interface, on board MAC & PHY, 8 Kbytes of Buffer RAM and an SPI serial interface. Many microcontrollers have built-in Ethernet peripheral, like the PIC18F97J60, this PIC18 Microcontroller has an integrated 10Mbps Ethernet communications peripheral but many other microcontrollers don’t have a built-in Ethernet peripheral.įor microcontrollers which don’t have an integrated Ethernet peripheral, Microchip offers a serial Ethernet chip that can easily be used by any microcontroller with an SPI interface to provide Ethernet capability to the application. Most of computers nowadays have an Ethernet port implemented on them so it is with many electronic devices. With just a network switch, many different devices can easily communicate with one another with Ethernet, allowing different devices and equipment to be accessed remotely and this also provides a cost-effective and reliable means of remote control and monitoring. Ethernet is the leading wired standard for networking as it enables to connect a very large number of computers, microcontrollers and other computer-based equipment to one another.
