5_Inkplate_SD_BMP example for e-radionica Inkplate6
5_Inkplate_SD_JPEG_pictures example for e-radionica Inkplate6
For this example you will need a micro USB cable, Inkplate6 and a SD card loaded with
image1.bmp and image2.bmp file that can be found inside folder of this example.
pyramid.jpg file that can be found inside folder of this example.
Select "Inkplate 6(ESP32)" from Tools -> Board menu.
Don't have "Inkplate 6(ESP32)" option? Follow our tutorial and add it:

To work with SD card on Inkplate, you will need to add one extra library.
Download and install it from here: https://github.com/e-radionicacom/Inkplate-6-SDFat-Arduino-Library
You can open .bmp files that have color depth of 1 bit (monochrome bitmap), 4 bit, 8 bit and
24 bit AND have resoluton smaller than 800x600 or otherwise it won't fit on screen.
You can open .jpg files that have resoluton smaller than 800x600 or otherwise it won't fit on screen.
Format your SD card in standard FAT fileformat.
