 ===== Example =====
+This example connects a 20×4 PCF8574 character LCD at address ''0x27'' to the MPAINO-8A8R(T) I2C port. Change the ''IclcdBegin()'' arguments if your LCD has a different address or size.
 <code cpp>

+const uint8_t heart[8] = {0, 10, 31, 31, 14, 4, 0, 0};

   * On MPAINO, using D20/D21 for external interrupts prevents simultaneous I²C use.
   * ''IclcdCommand()'' can change the LCD state directly. Use it only if you understand HD44780 commands.
