Ce este Raspberry Pi ?

first test_raspberrypi

RaspberryPi, zis RasPi, este un computer care ruleaza Linux, dar are dimensiunile unei carti de credit si costa 35$ (sau 25$ modelul fara Ethernet).

  • iesire HDMI pentru conectare la TV sau iesire AV Jack/RCA pentru TV analogic
  • 2xUSB pentru mouse si tastatura
  • 1xRJ45 Ethernet pentru acces internet
  • 1xMIPI CSI Camera
  • soclu SD card pe care ruleaza sistemul de operare
  • interfata GPIO cu 18 pini intrari/iesiri digitale, UART, SPI, i2C
  • alimentare externa 5V 700mA prin conector standard microUSB










Raspberry Pi este un microcontroler

raspi logo Recunosc, este mai mult de atat, dar daca ma intrebi care e diferenta intre un procesor si un microcontroler ti-as zice ca microcontrolerul integreaza in acelasi cip si procesor si memorii si porturi si pini I/O.
Raspberry Pi este un sistem pe o singura placa, dar pentru ca integreaza tot ce ai nevoie pe aceasta placa, poti sa-l consideri un microcontroler, un sistem cu microcontroler.
Daca pana acum ai scris programe pentru PC sau pentru microcontroler, de acum inainte trebuie sa-ti schimbi modul de gandire. Vei scrie programe pentru Raspberry Pi. Este la fel de ieftin ca un sistem cu microcontroler si la fel de simplu ca un PC.
