Standalone/VMWare Thingspeak and enc28j60

Hi guys,

I successfully installed standalone Thingspeak on Ubuntu. Unfortunatelly I'm stuck little bit just now. As a newbie I have been searching any usuable tips to upload data by enc28j60 into the local thngspk for last 3 days and - nothing usuable.

Every sketch for enc28j60 with ethercard library I've found contains definition of server like this:

• const char website PROGMEM = "api.thingspeak.com"; (for example here)

I need to replace this domain address by IP local 192.168.0.159:3000. A plain substitution of text in brackets doesn't work. Could anybody suggest me any hint at least? How and where shall I change a mentioned code described on the hyperlink?

Eventually, this joined sketch for ESP8266 with AT comands is workable - hence I'm sure the local server is OK.

Thank you very much

Tom
