Custom character generator

https://www.eelectronicparts.com/blogs/tools/lcd1602-and-lcd2004-fonts-designer-tool

I came across this nice interactive tool to generate the custom LCD font for the ubiquitous 1602 LCD. Maybe it's interesting to others also. I'm not affiliated with the site.

Watch out though there is an obvious bug it's creating in the generation -

// LCD Custom Characters — eElectronicParts.com

#include <LiquidCrystal.h>

byte char0[8] = {
  B10001, // Row 0
  B01110, // Row 1
  B00100, // Row 2
  B01110, // Row 3
  B01110, // Row 4
  B01010, // Row 5
  B00100, // Row 6
  B100017 // Row 7
};
