GPIO Settings
Configure operation mode and value for each Programmable I/O pins.
Eddy includes GPIO pins that output 3.3V or detect 3.3V signals.
Eddy-CPU has 16 pins, Eddy-S1/Pin has 4 pins, but Eddy-S1/DB9 and Eddy-S1/DB9-PoE models do not
have any GPIO pins.
You can detect either any 3.3V signals from external device, or output 3.3V signal to the external
device. You can also program a customized GPIO application, and you can implement it with the SDK
included in the Eddy development kit.
After changing values, you need to click
‘Submit’
button. Then you will see the same page with
modified values. Please note that you have to
‘Save & Reboot’
in order to see these changes in effect.
Changes will be discarded if you do not save current settings.
Different Eddy modules support different port number of GPIOs. Eddy Web server automatically senses
connected Eddy module and its supported GPIO ports and displays it on the Web.
If no GPIO is present in the current model, GPIO settings page is not available.
