Raspberry Pi: o hardware para Python

  1. 1. Marcelo Melo@marcelorangeA3M INNOVATIONSARDUINO-CERaspberry Pi: O Hardware para Python
  2. 2. Motivação● Com o surgimento do Arduino em 2005, na Itália, está cada vez mais popular autilização de sistemas embarcados por diversos tipos de pessoas, mesmo não sendo daárea de tecnologia!● As placas estão sendo desenvolvidas cada vez menores, mais rápidas e maisacessíveis tanto pela linguagem de programação quanto financeiramente!● A Raspberry Pi não tem o propósito de acabar com o Arduino e sim, coexistir com ele!
  3. 3. O que é a framboesa?Desenvolvida pelo inglês Ben Upton, um professor e desenvolvedor-arquiteto da Bradcom,juntamente com seus colegas, A Raspberry Pi, cuja fundação criada por eles recebe o mesmonome, tem como princípio a criação de um computador de baixíssimo custo para o ensino daciência da computação nas escolas de países em desenvolvimento utilizando a linguagemPython. Lançada oficialmente em 2012, esgotou o 1º estoque em poucos minutos!Ben Upton - Raspberry Pi Foundation
  4. 4. Modelos
  5. 5. EspecificaçõesO Raspberry Pi não possui um relógio de tempo real (RTC), portanto os dados de data/hora são perdidosA cada reinicialização, devendo, portanto usar um Network Time Protocol (NTP), utilizar um RTC externo oufornecer a hora ao sistema de forma manual.
  6. 6. O que precisa para começar?
  7. 7. O que você pode fazer com ela?● Web Server;● Servidor de Arquivos;● Print Server;● XBMC (Inexpensive Media Center);● Gateway;● Estação Metereológica;● Integração com outros sistemas, etc
  8. 8. O que você pode fazer com ela?

  12. 12. Desktop Raspian
  13. 13. GPIOPinos de uso geral
  14. 14. GPIOInstalando RPi.GPIO
  15. 15. Hello World GPIO!$ sudo python>>> import RPi.GPIO as GPIO>>> GPIO.setup(18, GPIO.OUT)>>> GPIO.output(18, False)>>> GPIO.output(18, True)
  16. 16. O que conectar ao RPi?
  17. 17. Interagindo com o mundoLISTA DE MATERIAIS- 1x Raspberry Pi 512MB- 1x Camera USB Logitech- 1x Base Robótica RP5- 2x Baterias 18650 3,7V x 2500mA- 1x Driver L293d- 1x Chave Alavanca on-off- 1x Transistor 7805- 2x capacitores 1000u x 16v- 2x cabos micro USB- 1x Puxa Saco Plástico OU- outros: parafusos, fios, solda,abraçadeiras.
