I have made an timer using a Nokia 5110 display, and now I want to change the display to a better display. I have bought a cheap HY-1.8 SPI
display from ebay. It's a nice display, but there is some problems I can't find the answer to myself.
Is it possible to show a bmp, or some other kind of picture without using the SD card? I'm using the Adafruit library. I want a boot image and 3 logos.
I also want to know if there is a way to use an other font, without a SD card? I only need numbers from 0 to 9, no letters.
I have limited space in the arduino, I know this, but the sketch I'm going to use is quite small.
Please help me!
