Introduction: This is just a time pass hobby project, I am trying to display some pictures (JPEG/PNG/BMP etc) on my 8×8 led dotmatrix display. You can see photos of my 8×8 led dotmatrix display showing some grayscale pictures. The main thing which you may notice is that the brightness of each led depends on the […]

Introduction: But now I can do this very easily by a simple digital signal processing using a microcontroller. It’s concept is very simple, ie we need to apply a proper delayed feedback in digital samples with in a circular buffer. I did this using an atmega32 microcontroller and it worked fine. This is simple but
