How to Display the Images with the Library
Declare all the libraries needed, here with an example based on NewSoftSerial library:
#include "NewSoftSerial.h" begin looks for the files images.dat and images.gci and returns the number of images or 0 in case of an error. a = myGallery.begin(&myLCD, "images"); index gives the number of the current image, while number gives the total number of images. Serial.print(myGallery.index(), DEC); showNext goes to the next image and then shows it. When the last image is reached, the next image is the first of the collection. a = myGallery.showNext(); showPrevious goes to the previous image and then shows it. When the first image is reached, the previous image is the last of the collection. a = myGallery.showPrevious(); showImage shows the image which number is specified, provided this number is within the range of the images. a = myGallery.showImage(1); |
