first release
Dependencies: mbed
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-W7500ECO Pin map
Initialize an analog pin
Initialize an P30 pin of WIZwiki-W7100ECO platform as an analog pin.
Read analog data from analog pin
Connect an analog device, such as a vriable resistor, to a0 pin. And read analog data.
Software
ADC Pin initialization
main.cpp
AnalogIn ain(P30);
Read analog data and print to serial port
main.cpp
printf("percentage: %3.3f%%\n", ain.read()*100.0f);
