+===== Vytvoření bitmapy =====
+Některé konvertory mají problém s určitými rozměry obrázků.
+Obrázek je nutno zmenšit ještě před koverzí a ideální je převést ho na stupně šedi nebo monochromatický taktéž před vlastní konverzí. Jako na potvoru pro konverzi malého obrázku 32x29 px fungoval jen Image2Code, který je trochu obtížnější získat
+Seznam konvertorů:
+  * GIMP [[https://www.gimp.org/downloads/]]
+  * LCD Assisant [[http://en.radzio.dxp.pl/bitmap_converter/]]
+  * Image2Code https://github.com/adafruit/Adafruit-GFX-Library#useful-resources
+Konvertory krom gimpu jsem prověřil na virustotal.com, nicméně i tak doporučuji překontrolovat je znovu.
+Image2Code je nástroj poskytnutý v sekci použitelných zdrojů ke knihovně Adafruit GFX napsaný v javě. Je nutno ho zkompilovat přes příkaz "gradle build". Pokud vám to nepůjde, mohu vám v případě windows poslat již sestavenou verzi
+ Pokud se nepovede konverze z nějakého důvodu ani tak, pak vložte do pole tento obsah:

+===== Kód programu =====
 Na začátku je nutno nainstalovat si v Arduino IDE v menu: Nástroje/Spravovat knihovny následující knihovny:
   * SSD1306 by adafruit(v mé době ver. 1.28)
   * Adafruit GFX by adafruit (v mé době ver. 1.36)
-Kód je upraveným příkladem pro SSD1306.
+V kódu je komentář "ZDE VLOZIT hexaznaky bitmapy".
+Pro zkopírování kód stačí dvojklik na kód a ctrl+c
