![]() ![]() Keep in mind that the Arduino’s 5V pin goes to the VCC pin as well as to the LED+ pin. The wiring is more or less straight forward. I created a fritzing file that shows all the wiring: To make it work, you have to connect many wires between the Arduino and the TFT display. Therefore, I want to share how I made it work. Nevertheless, I did not came across any example code that worked out of the box for my setup. ![]() The second problem seemed to be caused by some memory leaks in the code. I did some research on the Internet and I found out that many people ran into similar problems. The application started to freeze and showed the same image forever instead of displaying the next image after a chosen time. Second, my first prototypes stopped to work after about 5 minutes. First, the colors of my image file did not match to the colors displayed by the KMR-1.8 (red and blue were interchanged). When I started to implement my first lines of codes and started to connect my Arduino Uno to the KMR-1.8 SPI, I ran into two major problems. For these reasons, I thought making such an digital picture frame will turn out very easy. Moreover, I looked up the Internet and found ready-to-use libraries for the in-built SD card reader as well as showing images on the TFT display. When I digged up my KMR-1.8 SPI, I realized that it has also an in-built SD card reader. I was remembering myself that I already own a small TFT display, the KMR-1.8 SPI, that works out of the box with an Arduino Uno. Recently, I had the idea to make a digital picture frame-one of these kinds which load images from SD cards and show each image for some time. KMR-1.8 SPI TFT display with a resolution of 128 (height) x 160 (width) ![]()
