Melt 7-segment LCD Arduino library

Compatible models are MT-10T* based on I2C PCF8576.

Features

  • Extended table of chars 0-9, A-Z, a-z, special chars -=_~*."
  • Dot is dispayed as modifier to a char
  • Replacable/customizable char mapper
  • The char map is stored in PROGMEM
  • The bundled char mapper is optimized for speed
  • Smart transmission planning

The library tries to optimize transmission by sending only the changed parts but only if distance between them is 3 or more. The initializaton of i2c communication has overhead that is close to the cost of sending 2 chars in bulk.
