This post introduces how to use WIZnet chip solution such like as W3100A, W5100, W5200, W5300, and W5500 with BASIC source code on BASCOM-AVR & BASCOM-8051.
BASCOM-AVR & BASCOM-8051 are BASIC complier & IDE development tools. These can implement with BASIC source code on WIZnet chip solutions.
Here you can find a step-by-step tutorial about the Bascom-AVR code to drive an AVR and an WIZ830MJ Ethernet controller. This tutorial is based on the Arduino Mega shield with WIZ830MJ, VS1053 MP3 decoder, Micro-SD-slot, 128 Kbyte SRAM from Michael Köcher.
