Asụsụ mmemme ngwa ngwa na Raspberry Pi

Raspberry PI 3 Model B+

N'ime nkuzi a, anyị ga-agafe isi nke iji Swift na Raspberry Pi. Raspberry Pi bụ obere kọmpụta nwere otu bọọdụ dị ọnụ ala nke ikike ya nwere naanị site na akụrụngwa mgbako. A maara ya nke ọma n'etiti geeks teknụzụ na ndị na-anụ ọkụ n'obi DIY. Nke a bụ nnukwu ngwaọrụ maka ndị chọrọ ịnwale echiche ma ọ bụ nwalee otu echiche na omume. Enwere ike iji ya rụọ ọrụ dịgasị iche iche, ma na-adaba ngwa ngwa ọ fọrọ nke nta ka ọ bụrụ ebe ọ bụla - dịka ọmụmaatụ, enwere ike itinye ya na mkpuchi nlekota ma jiri ya dị ka desktọọpụ, ma ọ bụ jikọọ na bred iji chịkwaa sekit eletriki.

Asụsụ mmemme nke Malinka bụ Python. Ọ bụ ezie na Python dị mfe iji, ọ nweghị nchekwa ụdị, gbakwunyere na ọ na-eri ọtụtụ ebe nchekwa. N'aka nke ọzọ, Swift nwere njikwa ebe nchekwa ARC na ọ fọrọ nke nta ka ọ bụrụ ugboro 8 ngwa ngwa karịa Python. Ọ dị mma, ebe ọ bụ na ọnụọgụ RAM na ike ịgbakọ nke Raspberry Pi processor nwere oke, iji asụsụ dị ka Swift na-enye gị ohere ịbawanye ike nke ngwaike nke obere PC a.

Nwụnye OS

Tupu ịwụnye Swift, ịkwesịrị ịhọrọ OS. Iji mee nke a ị nwere ike jiri otu n'ime nhọrọNdị mmepe nke ndị ọzọ na-enye. Nhọrọ a na-ahụkarị bụ Raspbian, OS gọọmentị sitere na Raspberry Pi. Enwere ọtụtụ nhọrọ iji wụnye Raspbian na kaadị SD; N'ọnọdụ anyị, anyị ga-eji balenaEtcher. Nke a bụ ihe ị ga-eme:

• Budata ụdị Raspbian OS kacha ọhụrụ site n'ebe a.
• Hazie kaadị SD ka ọ bụrụ abụba site na iji Disk Utility.
• Anyị na-eji BalenaEtcher maka ibugote na kaadị ahazigharịrị.

Nzọụkwụ abụọ: Hazie kaadị SD na MS-DOS (FAT)

Nzọụkwụ atọ: jiri balenaEtcher mejupụta Raspbian na kaadị

Anyị na-akwado nkuzi kpụ ọkụ n'ọnụ n'efu na mmụta igwe maka ndị mbido:
Anyị na-ede ụdị mmụta igwe mbụ n'ime ụbọchị atọ — Septemba 2-4. Usoro nkuzi kpụ ọkụ n'ọnụ n'efu nke na-enye gị ohere ịghọta ihe mmụta igwe ma mụta ka esi arụ ọrụ na data mepere emepe sitere na ịntanetị. Anyị na-amụtakwa ịkọ ọnụ ahịa mgbanwe dollar site na iji ihe nlereanya nke onwe ya.

Ntọala Raspberry Pi

Ọkara ebe ahụ ugbua! Anyị nwere kaadị SD nwere OS nke anyị ga-eji, mana arụnyebeghị sistemụ arụmọrụ. Enwere ohere abụọ maka nke a:

• Jiri ihe nleba anya, ahụigodo na òké ejikọrọ na ngwaọrụ.
• Mee ihe niile site na PC ọzọ site na SSH ma ọ bụ iji eriri USB Console.

Ọ bụrụ na nke a bụ ahụmịhe izizi gị na Pi, ana m akwado nhọrọ #1. Ozugbo etinyere kaadị Raspbian OS SD n'ime Pi, jikọọ eriri HDMI, òké, ahụigodo, na eriri ọkụ.

Pi kwesịrị buut mgbe agbanyere ya. Ekele! Ugbu a ị nwere ike iwepụta obere oge ịmụta gbasara desktọpụ gị na ike ya.

Ịwụnye Swift

Iji wụnye Swift na Raspberry, ịkwesịrị ijikọ ya na ịntanetị (iji Ethernet ma ọ bụ WiFi, dabere na ụdị osisi). Ozugbo ejikọrọ ịntanetị, ị nwere ike ịmalite ịwụnye Swift.

Enwere ike ime ya n'ụzọ abụọ. Mbụ - ịmepụta ngwa ngwa Swift nke gị, nke abụọ bụ iji ọnụọgụ abụọ agbakọtara. Ana m akwado usoro nke abụọ, ebe ọ bụ na nke mbụ ga-achọ ọtụtụ ụbọchị nkwadebe. Ụzọ nke abụọ pụtara ekele otu Swift-ARM. O nwere repo nke ị nwere ike tinye Swift site na iji apt (An'iru Pna-arụ ọrụ Tlol).

Ọ bụ ngwa ahịrị iwu, ụdị dị ka App Store maka ngwa na ngwugwu maka ngwaọrụ Linux. Anyị na-amalite ịrụ ọrụ na apt site na ịbanye apt-get na ọdụ. Na-esote, ịkwesịrị ịkọwapụta ọtụtụ iwu ga-eme ka ọrụ a na-arụ dokwuo anya. N'ọnọdụ anyị, anyị kwesịrị ịwụnye Swift 5.0.2. Ngwunye kwekọrọ nwere ike ịbụ chọta ebe a.

Ọfọn, ka anyị malite. Ugbu a anyị maara na anyị ga-etinye Swift site na iji apt, anyị kwesịrị ịgbakwunye repo na ndepụta nke ebe nchekwa.

Tinye/wụnye iwu repo ngwa ngwa-ogwe aka yiri nke a:

curl -s <https://packagecloud.io/install/repositories/swift-arm/release/script.deb.sh> | sudo bash

Na-esote, wụnye Swift site na repo agbakwunyere:

sudo apt-get install swift5=5.0.2-v0.4

Ọ gwụla! Awụnyela Swift na Raspberry anyị.

Ịmepụta oru nyocha

N'oge ahụ Swift REPL anaghị arụ ọrụ, ma ihe ọ bụla ọzọ na-eme. Maka ule ahụ, ka anyị mepụta ngwugwu Swift site na iji Swift Package Manager.

Mbụ, mepụta ndekọ aha MyFirstProject.

mkdir MyFirstProject

Na-esote, gbanwee akwụkwọ ndekọ aha na-arụ ọrụ ugbu a ka ọ bụrụ MyFirstProject emepụtara ọhụrụ.

cd MyFirstProject

Mepụta ngwungwu Swift ọhụrụ enwere ike ime ya.

swift package init --type=executable

Ahịrị atọ ndị a na-emepụta ngwugwu Swift efu akpọrọ MyFirstProject. Iji mee ya, tinye iwu ọsọ ọsọ.

Ozugbo achịkọtachara, anyị ga-ahụ nkebi ahịrịokwu ahụ “Ndewo, ụwa!” na akara iwu.

Ugbu a anyị mepụtara mmemme Pi mbụ anyị, ka anyị gbanwee ihe ole na ole. Na MyFirstProject ndekọ, ka anyị mee mgbanwe na main.swift faịlụ. O nwere koodu a na-egbu mgbe anyị na-eji iwu ọsọ ọsọ na-agba ọsọ ngwugwu.

Gbanwee ndekọ ka ọ bụrụ Sources/MyFirstProject.

cd Sources/MyFirstProject 

Na-edezi faịlụ main.swift site na iji arụnyere n'ime ya nano nchịkọta akụkọ.

nano main.swift

Ozugbo onye nchịkọta akụkọ mepere, ị nwere ike ịgbanwe koodu nke mmemme gị. Ka anyị jiri nke a dochie ọdịnaya nke main.swift faịlụ:

print("Hello, Marc!")

N'ezie ị nwere ike itinye aha gị. Ka ịchekwaa mgbanwe ị ga-eme ihe ndị a:

• CTRL + X ka ịchekwaa faịlụ ahụ.
• Kwado mgbanwe ndị ahụ site na ịpị "Y".
• Kwado mgbanwe na faịlụ main.swift site na ịpị Tinye.

Emeela mgbanwe niile, ugbu a bụ oge ịmalitegharị mmemme ahụ.

swift run

Ekele! Ozugbo achịkọtara koodu ahụ, ọnụ ahịa kwesịrị igosi ahịrị gbanwetụrụ.

Ugbu a arụnyere Swift, ị nwere ihe ị ga-eme. Yabụ, iji jikwaa ngwaike, dịka ọmụmaatụ, LEDs, servos, relays, ị nwere ike iji ọba akwụkwọ nke ngwa ngwa maka mbadamba Linux / ARM, nke a na-akpọ. SwiftyGPIO.

Nwee anụrị ịnwale Swift na Raspberry Pi!
