-In this testI am striving to answer first whether rendering updates will be fast enough for reasonable use and second whether there will be any memory left to do anything interesting. +For general information on this displaysee [[arduino:displays_for_classic_arduinos:nokia_5110_displays_and_classic_arduinos | this]]
  
 One might expect this 84×48 display with 1 bit color depth to be updateable pretty quickly even with a torpid Uno/Nano/Pro Mini, and indeed it is. The frame update time of 100 ms (the inverse of the fps noted in the [[display_nokia_5110_u8g2_counter.ino | source code]]) is respectable, and  One might expect this 84×48 display with 1 bit color depth to be updateable pretty quickly even with a torpid Uno/Nano/Pro Mini, and indeed it is.

 The glare on the edges is an artifact from the four LEDs used to backlight the display. In real life the arifact doesn' appear as glare, but it is clear on inspection that there are four sources of illumination.  The glare on the edges is an artifact from the four LEDs used to backlight the display.
