The reported | + | I decided to get an idea of what the processing time and memory overhead using BigCrystal with a 20x4 display was. I used a 5V 16 Mhz Nano, and the display is probably an STN unit. The frame update time is around 14 msec and varies with the number of big characters being drawn. Memory use is 15% of program storage and 6% of dynamic memory. Because these numbers are so low, I didn't bother doing a test of the LiquidCrystal library on its own. |
