5_Inkplate_SD_BMP 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.
|
|
Select "Inkplate 6(ESP32)" from Tools -> Board menu.
|
|
Don't have "Inkplate 6(ESP32)" option? Follow our tutorial and add it:
|
|
https://e-radionica.com/en/blog/add-inkplate-6-to-arduino-ide/
|
|
|
|
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.
|
|
Format your SD card in standard FAT fileformat.
|
|
|
|
This example will show you how you can read .bmp files (pictures) from SD card and
|
|
display that image on e-paper display.
