I am using SD card interfaced to arduino uno.SD Card contains a text file which contains
24.85,66.8, Buleji
24.82,67.02, Bath Island
24.87,67.03, Currie Reservoir
23.75,68.22, Gharo Creek
23.78,68.23, Dafa
23.76,68.24, Dufi Creek
23.86,68.25, Nar Creek
23.86,68.25, Wangur Creek
23.96,68.28, Muni Creek
23.87,68.3, Mai Creek
23.8,68.37, Pabewari Creek
23.55,68.46, Sugar Creek
23.84,68.48, Padala Creek
23.72,68.52, Kori Creek
23.52,68.52, Pipar
5lakh lines are present like this.
These are latitude and longitude values along with its location name.
I have a GPS Module interfaced which gives lat and long positions.
I want to check latitude and longitude positions with the text file and return the coresponding location name.
For Eg:if lat,long values from gps module is 23.55,68.46 then it should search for this in text file and return Sugar Creek.
I tried using myFile.find() to search for the string in text file.But it didn't work.
Can anyone please tell me how to achieve this.
Thanks in advance.
