Fork of AnalogIn-HelloWorld_WIZwiki-W7500 by WIZnet

Prerequisite

This Program is an example of how to get analog data with WIZwiki-W7500 board A0 Pin.

To implement this function, you need a Platform board only.

  • WIZwiki-W7500 from WIZnet (Platform board)

Hardware Configuration

WIZwiki-W7500 Pin map

pin map

Initialize an analog pin
Initialize an A0 pin of WIZwiki-W7100 platform as an analog pin.

Read analog data from analog pin
Connect an analog device, such as a variable resistor, to a0 pin. And read analog data.

Software

ADC Pin initialization

main.cpp

AnalogIn   ain(A0);

Read analog data and print to serial port

main.cpp

printf("percentage: %3.3f%%\n", ain.read()*100.0f);
