Fata de partea I, in care am prezentat date generale si am comandat integratul TEA5767 cu placa Arduino si am afisat date pe un LCD cu 16 coloane si 2 randuri, apoi pe unul compatibil Nokia 5110, acum voi conectata si modulul de timp real (RTC) cu integratul DS1307, astfel incat voi avea si informatii despre ora si data. Dupa ce am modificat un pic sketch-ul anterior pentru a muta informatiile legate de frecventa radio, am urmatoarea prezentare: Am completat sketch-ul cu partea de RTC, obtinand: /********************************************************************* This is an example sketch for our Monochrome Nokia 5110 LCD Displays Pick one up today in the adafruit shop! ------> http://www.adafruit.com/products/338 These displays use SPI to communicate, 4 or 5 pins are required to interface Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!
