/* Simulacni verze ovladace pro GPIO piny drv_gpio */

/*
 * @file     drv_gpio.h
 * @brief    Simple GPIO driver for LED and push buttons Freescale KL25Z
 * @version  V1.00
 * @date     17. July 2015
 *
 * @note
 *
 * Ukazkovy program pro Programovani mikropocitacu
 * Ovladac pro LED a tlacitka. Umoznuje ovladat tlacitka na vyvojovem kitu
 * s FRDM-KL25Z ve stylu jako Arduino funkce digitalRead, digitalWrite and pinMode.
 *
 * Pozor: toto neni priklad univerzalniho ovladace pro mapovani nejakych cisel/nazvu pinu
 * na fyzicke piny mikrokontroleru. Piny jsou mapovany primitivne, natvrdo pomoc switch.
 * Nazvy funkci neodpovidaji doporucene konvenci {nazev_ovladace}_{nazev_funkce}, aby byla
 * zajistena jejich podobnost funkcim Arduina, ktere jsou obecne zname.
 *
 * Vyjimky z doporucenych konvenci kvuli strucnejsimu zapisu programu:
 * - funkce pinWrite, pinMode, pinRead nezacinaji predponou modulu (GPIO)
 * - nazvy polozek vyctovych typu (enum) neobsahuji nazev modulu (GPIO).
