Raspberry Pi 40-pin GPIO Header

• Mbali yamphamvu ya Raspberry Pi ndi mzere wa zikhomo za GPIO (zofuna zambiri / zotulutsa) m'mphepete mwa bolodi. Mutu wa GPIO wa pini 40 umapezeka pama board onse a Raspberry Pi (opanda anthu pa Raspberry Pi Zero, Raspberry Pi Zero W ndi Raspberry Pi Zero 2 W). Asanayambe Raspberry Pi 1 Model B+ (2014), matabwa anali ndi mutu wamfupi wa pini 26. Mutu wa GPIO pama board onse (kuphatikiza Raspberry Pi 400) uli ndi pitch 0.1 ″ (2.54mm).

  

• Kuti mudziwe zambiri, onani Raspberry Pi Hardware - GPIO ndi Mutu wa 40-pin.
• Kuti mumve zambiri za Raspberry Pi HATs, chonde onani Mabodi Owonjezera ndi Ma HAT.

SPI Port Connection

• SPI imayimira Serial Peripheral Interface, serial full-duplex and synchronous interface. Mawonekedwe a synchronous amafuna chizindikiro cha wotchi kuti atumize ndi kulandira deta. Chizindikiro cha wotchi chimalumikizidwa pakati pa chowongolera chimodzi chapakati ("mbuye") ndi zida zingapo zotumphukira ("akapolo"). Mosiyana ndi kulumikizana kwa UART, komwe kumakhala kofanana, chizindikiro cha wotchi chimawongolera nthawi yomwe deta iyenera kutumizidwa komanso nthawi yomwe iyenera kukhala yokonzeka kuwerengedwa.
• Kachipangizo kokha kamene kamatha kuwongolera wotchi ndikupereka chizindikiro cha wotchi ku zida zonse za akapolo. Zambiri sizingasinthidwe popanda chizindikiro cha wotchi. Onse mbuye ndi kapolo akhoza kusinthanitsa deta wina ndi mzake. Palibe decoding yofunikira.
• ESP32 ili ndi mabasi anayi a SPI, koma awiri okha omwe amapezeka kuti agwiritsidwe ntchito, ndipo amadziwika kuti HSPI ndi VSPI. Monga tanenera kale, mu kulankhulana kwa SPI, nthawi zonse pamakhala wolamulira mmodzi (wotchedwanso mbuye) yemwe amalamulira zipangizo zina zotumphukira (zomwe zimadziwikanso kuti akapolo). Mutha kusintha ESP32 ngati mbuye kapena kapolo.

  

• Pa espBerry, zizindikiro zoperekedwa ku ma IO osasintha:

  

• Pansipa chithunzi chikuwonetsa ma sign a SPI kuchokera ku gawo la ESP32 kupita kumutu wa RPi GPIO monga gawo lachiwonetsero.

  

• Pali mitundu yambiri ya matabwa a ESP32 omwe alipo. Mabodi ena kusiyapo espBerry amatha kukhala ndi zikhomo zosiyana za SPI, koma mutha kupeza zambiri zamapini osasinthika kuchokera pazosunga zawo. Koma ngati mapini osasinthika sanatchulidwe, mutha kuwapeza pogwiritsa ntchito chojambula cha Arduino (gwiritsani ntchito ulalo woyamba pansipa).
• Kuti mudziwe zambiri, onani:
  • ESP32 SPI Tutorial Master Slave Communication Example…
  • Espressif GPIO Matrix ndi IO_MUX…
• EspBerry imagwiritsa ntchito kulumikizana kwa VSPI ngati kusakhazikika, kutanthauza kuti ngati mutapita ndi zizindikiro zosasintha, simuyenera kukumana ndi mavuto. Pali njira zosinthira pini ndikusinthira ku HSPI (monga tafotokozera pamwambapa), koma sitinafufuze zochitika izi za espBerry.
• Onaninso gawo lathu pa SPI Port Programming.

Kulumikiza kwa seri (UART) Port

• Kupatula pa doko la USB lolowera, gawo lachitukuko la ESP32 lili ndi zolumikizira zitatu za UART, mwachitsanzo, UART0, UART1, ndi UART2, zomwe zimapereka kulumikizana kosagwirizana pa liwiro la 5 Mbps. Madoko awa amatha kujambulidwa pafupifupi pini iliyonse. Pa espBerry, tidapereka IO15 ngati Rx ndi IO16 ngati Tx, yomwe imalumikizidwa ndi GPIO16 ndi GPIO20 pamutu wa 40-pin monga tawonera apa:

  

• Tasankha kuti tisagwiritse ntchito chizindikiro cha RX/TX (GPIO3/GPIO1) pa ESP32 DevKit, popeza nthawi zambiri amagwiritsidwa ntchito poyesa kusindikiza kudzera pa Serial Monitor ya Arduino IDE. Izi zitha kusokoneza kulumikizana pakati pa ESP32 ndi RPi HAT. M'malo mwake, muyenera kupanga mapu a IO16 ngati Rx ndi IO15 monga Tx pa pulogalamu iliyonse monga momwe zafotokozedwera mu gawo la Mapulogalamu a bukhuli.
• Onaninso gawo lathu pa Serial (UART) Programming.

Mapulogalamu

• M'munsimu, tifotokoza mwachidule mbali zofunika kwambiri zamapulogalamu a espBerry. Monga tanenera kale m'bukuli, tiwonjezera maumboni a pa intaneti pomwe tikuwona kuti zowonjezera ndizofunikira.
• Kuti mumve zambiri, pulojekiti ya manja pa samples, onaninso athu Malangizo a ESP32 Programming.
• Kuphatikiza apo, pali ambiri akaleampza Zolemba za ESP32, zomwe zimayenera kulipidwa.
• Komabe, tikulimbikitsidwa kugwiritsa ntchito Ma Electronic Projects okhala ndi ESP8266 ndi ESP32, makamaka pamapulojekiti anu opanda zingwe. Inde, mabuku ambiri abwino ndi zida zaulere zapaintaneti zilipo masiku ano, koma ili ndi buku lomwe tikugwiritsa ntchito. Zinapangitsa njira yathu ku Bluetooth, BLE, ndi WIFI kukhala kamphepo. Kupanga mapulogalamu opanda zingwe popanda zovuta kunali kosangalatsa, ndipo timagawana nawo patsamba lathu web malo.

  

Kukhazikitsa ndi Kukonzekera Arduino IDE

• Mapulogalamu athu onse sampLes adapangidwa pogwiritsa ntchito Arduino IDE (Integrated Development Environment) chifukwa chosavuta kuyiyika ndikugwiritsa ntchito. Kuphatikiza apo, pali miyandamiyanda ya zojambula za Arduino zomwe zikupezeka pa intaneti za ESP32.
• Pokhazikitsa, tsatirani izi:
  • Gawo 1: Gawo loyamba lingakhale kutsitsa ndikuyika Arduino IDE. Izi zitha kuchitika mosavuta potsatira ulalo https://www.arduino.cc/en/Main/Software ndikutsitsa IDE kwaulere. Ngati muli nayo kale, onetsetsani kuti muli nayo yatsopano.
  • Gawo 2: Mukayika, tsegulani Arduino IDE, ndikupita ku Files -> Zokonda kuti mutsegule zenera lokonda ndikupeza "Additional Boards Manager URLs:” monga zikuwonetsedwa pansipa:

    

    • Bokosi lolemba likhoza kukhala lopanda kanthu kapena lili ndi zina URL ngati mudagwiritsapo kale bolodi lina. Ngati ilibe kanthu, ingoikani pansipa URL m'bokosi lolemba.
      https://dl.espressif.com/dl/package_esp32_index.json
    • Ngati bokosi lolemba lili kale ndi zina URL ingowonjezerani izi URL kwa icho, alekanitse onse ndi koma (,). Athu anali kale ndi a Teensy URL. Tidangolowa mu URL ndikuwonjezera koma.
    • Akamaliza, alemba pa OK ndi zenera adzazimiririka.
  • Gawo 3: Pitani ku Zida -> Mabodi -> Oyang'anira Board kuti mutsegule zenera la oyang'anira Board ndikufufuza ESP32. Ngati ndi URL idayikidwa bwino zenera lanu liyenera kupeza chophimba pansipa ndi batani instalar, ingodinani batani instalar ndipo bolodi lanu liyenera kukhazikitsidwa.

    
    Chojambula pamwambapa chikuwonetsa ESP32 itayikidwa.

  • Gawo 4: Musanayambe kupanga, muyenera kukhazikitsa chosankha choyenera cha ESP32 hardware (pali njira zingapo). Yendetsani ku Zida -> Mabodi ndikusankha ESP32 Dev Module monga zikuwonetsedwa apa:

    

  • Gawo 5: Tsegulani woyang'anira chipangizocho ndikuwona kuti ESP32 yanu yalumikizidwa pa COM.

    

• Mukamagwiritsa ntchito espBerry, yang'anani Silicon Labs CP210x USB ku UART Bridge. Pakukhazikitsa kwathu zikuwonetsa COM4. Bwererani ku Arduino IDE ndi pansi Zida -> Port, sankhani Port komwe ESP yanu imalumikizidwa.

  

• Ngati ndinu woyamba ndi Arduino IDE, chonde onani Kugwiritsa ntchito Arduino Software (IDE).

SPI Port Programming

• Zotsatirazi zikungoyimira mwachiduleview pulogalamu ya SPI. Kupanga mapulogalamu a SPI sikophweka, koma tikayamba ntchito yatsopano, timayang'ana ma code pa intaneti (mwachitsanzo, github.com).
• Mwachitsanzo, pokonza chowongolera cha MCP2515 CAN, tikugwiritsa ntchito mtundu wosinthidwa wa Laibulale ya MCP_CAN ya Arduino yolembedwa ndi Cory Fowler, mwachitsanzo, tikugwiritsa ntchito chidziwitso ndi mphamvu zake pantchito yathu.
• Komabe, ndikofunikira kuwononga nthawi kuti mumvetsetse mapulogalamu a SPI pamlingo woyambira. Mwachitsanzo, espBerry ili ndi zizindikiro za SPI zomwe zasonyezedwa apa:
