Handson Technology DSP-1182 I2C Serial Interface 1602 LCD Jagorar Mai Amfani da Module
Wannan shi ne I2C dubawa 16 × 2 LCD nuni module, wani high quality-2 line 16 hali LCD module tare da kan-jirgin bambanci iko daidaitawa, backlight da kuma I2C sadarwa dubawa. Don masu farawa na Arduino, babu ƙarin haɗaɗɗiyar haɗin da'irar direban LCD. Ainihin mahimmanci advantages na wannan I2C Serial LCD module zai sauƙaƙa haɗin da'irar, adana wasu fitilun I/O akan allon Arduino, ingantaccen haɓaka firmware tare da babban ɗakin karatu na Arduino.
Saukewa: DSP-1182

Hitachi's HD44780 tushen halayen LCD suna da arha sosai kuma ana samunsu sosai, kuma muhimmin sashi ne ga kowane aikin da ke nuna bayanai. Yin amfani da allon piggy-baya LCD, ana iya nuna bayanan da ake so akan LCD ta bas ɗin I2C. A ka'ida, irin waɗannan jakunkuna an gina su a kusa da PCF8574 (daga NXP) wanda shine babban manufa bidirectional 8 bit I/O mai faɗaɗa tashar jiragen ruwa wanda ke amfani da ka'idar I2C. PCF8574 da'irar siliki ce ta CMOS tana ba da babbar manufa ta fadada I/O mai nisa (wani 8-bit quasi-bidirectional) don yawancin iyalai masu sarrafa microcontroller ta hanyar bas mai layi biyu (I2C-bus). Lura cewa yawancin nau'ikan piggy-baya suna a tsakiya a kusa da PCF8574T (kunshin SO16 na PCF8574 a cikin kunshin DIP16) tare da adireshi tsoho na 0x27. Idan allon baya na piggy yana riƙe guntu PCF8574AT, to, adireshin bawa na tsoho zai canza zuwa 0x3F. A takaice, idan allon piggy-baya ya dogara ne akan PCF8574T kuma haɗin adireshin (A0-A1-A2) ba a haɗa shi da mai siyarwa ba zai sami adireshin bawa 0x27.
