MikroC - Ethernet Library ping demo for ENC28J60

Hello Pinalamrutiya,

if you are using 5v power supply for your MCU please note that you will need logic level translator since your ENC28J60 needs 3.3v power supply. ENC28J60 has +5v logic tolerant inputs but it's output has to be translated from 3.3v to 5v logic so MCU can properly recognize logic states. Please check this first, since this might be a problem.

Best regards,
Milos Vicentijevic

hello ..@milos.vicentijevic

yes i have my logic level shifter i.e. sn74hc573n for the SO pin of enc28j60 and the rest of the pins are 5v compitible for the 5v microcontroller.

hey reply me on my thread
"Ethernet PICtail plus daughter board and PIC18F4520"

thanks in advance

Hello,

I have answered you there.

In regards to the project, I am working on to communicate between dspic33ep512mu810 and ENC28J60. Where I am trying to PING ethernet chip from my PC through the router, but I am getting an error "host is unreachable". All the connection seems perfect. I am able to PING the router and my self (PC) but not to chip. Here below I am attaching source code and requesting to guide us to solve this problem.

Hi,

I believe that you have been answered on the following forum topics.
Just be sure to set your IP configs properly in the code.
Type "ipconfig /all" in the command prompt to check this out.
