Review on Arduino Resistive Interface Compatible Leonardo by Derek Evans

Revainrating 2 out of 5

Just too slow for single board computers

Warning: Drawing on this display is very slow. The text is drawn as a 1985 1200 baud dialer. Also, in the example code, there is a 1.5 second delay just to toggle the reset pin at startup. It must not be a violation of the terms of your project. If you look at the example code, it looks like the fonts are drawn with a single pixel. simultaneously, and each pixel requires a unique SPI transaction. It's very likely that this thing could work better with the right documentation and examples. I would update my rating and add stars if shown I couldn't find them somewhere obvious.

Pros
  • PWM backlight control, allows you to adjust the backlight to a comfortable level; Micro SD slot provides an easy way to save photos for viewing; Controlled via SPI, with only a few pins Arduino
Cons
  • Expensive
