Iyo Raspberry Pi 40-pini GPIO Musoro

• Chinhu chine simba cheRaspberry Pi ndiwo mutsara weGPIO (general-chinangwa chekuisa / kubuda) pini padivi pekumusoro kwebhodhi. Iyo 40-pini GPIO musoro unowanikwa pane ese aripo Raspberry Pi mabhodhi (asina vanhu paRaspberry Pi Zero, Raspberry Pi Zero W uye Raspberry Pi Zero 2 W). Pamberi peRaspberry Pi 1 Model B+ (2014), mabhodhi aisanganisira mupfupi 26-pini musoro. Iyo GPIO musoro pamabhodhi ese (kusanganisira iyo Raspberry Pi 400) ine 0.1 ″ (2.54mm) pini pitch.

  

• Kuti uwane rumwe ruzivo, tarisa kune Raspberry Pi Hardware - GPIO uye iyo 40-pini Header.
• Kuti uwane rumwe ruzivo nezve Raspberry Pi HATs, ndapota tarisa kune Wedzera-PaMabhodhi uye HATs.

SPI Port Connection

• SPI inomirira Serial Peripheral Interface, serial yakazara-duplex uye synchronous interface. Iyo synchronous interface inoda chiratidzo chewachi kuendesa uye kugamuchira data. Chiratidzo chewachi chinowiriraniswa pakati peimwe yepakati control ("tenzi") uye akawanda peripheral zvishandiso ("varanda"). Kusiyana neUART kutaurirana, iyo iri asynchronous, wachi chiratidzo chinodzora kana data richizotumirwa uye parinofanira kunge rakagadzirira kuverenga.
• Chete chigadziriso chinokwanisa kudzora wachi uye nekupa chiratidzo chewachi kumidziyo yese yevaranda. Data haigone kutamiswa pasina chiratidzo chewachi. Vese tenzi nemuranda vanogona kuchinjana data nemumwe. Hapana kudhindwa kwekero kunodiwa.
• ESP32 ine mabhazi mana eSPI, asi maviri chete anowanikwa kuti ashandiswe, uye anozivikanwa seHSPI neVSPI. Sezvambotaurwa, mukukurukurirana kweSPI, pane nguva dzose mutongi mumwe (anozivikanwawo satenzi) anodzora zvimwe zvigadzirwa zveparipheral (zvinozivikanwawo sevaranda). Unogona kugadzirisa ESP32 ingave tenzi kana muranda.

  

• Pa espBerry, masaini akagoverwa kune default maIOs:

  

• Pazasi mufananidzo unoratidza masiginecha eSPI kubva kuESP32 module kuenda kuRPi GPIO musoro sechidimbu kubva pane schematic.

  

• Kune marudzi akawanda eESP32 mabhodhi aripo. Mabhodhi kunze kwe espBerry anogona kunge aine akasiyana default SPI pini, asi iwe unogona kuwana ruzivo nezve default pini kubva padhetabheti ravo. Asi kana mapini akasarudzika asina kutaurwa, unogona kuwawana nekushandisa Arduino sketch (shandisa yekutanga link pazasi).
• Kuti uwane rumwe ruzivo, ona:
  • ESP32 SPI Tutorial Master Slave Communication Example…
  • Espressif GPIO Matrix uye IO_MUX…
• Iyo espBerry inoshandisa iyo VSPI yekubatanidza seyakagadzika, zvichireva kuti kana iwe ukaenda neiyo default masaini, haufanirwe kumhanya mumatambudziko. Pane nzira dzekushandura pini yekupihwa uye kuchinjisa kuHSPI (sezvinotsanangurwa mune mareferensi ari pamusoro), asi isu hatisati taongorora izvi zviitiko zve espBerry.
• Onawo chikamu chedu paSPI Port Programming.

Seri (UART) Port Connection

• Kunze kweiyo onboard USB port, iyo ESP32 yekuvandudza module ine matatu maUART interfaces, kureva, UART0, UART1, uye UART2, iyo inopa asynchronous kutaurirana nekumhanya kunosvika 5 Mbps. Aya ma serial ports anogona kumepu kunenge chero ipini. Pa espBerry, takapa IO15 seRx uye IO16 seTx, iyo yakabatana neGPIO16 uye GPIO20 pane 40-pini musoro sezvakaratidzwa pano:

  

• Isu takasarudza kusashandisa yakajairwa RX/TX (GPIO3/GPIO1) masiginecha paESP32 DevKit, sezvo achiwanzo shandiswa pakuedza maprints kuburikidza neSerial Monitor yeArduino IDE. Izvi zvinogona kukanganisa kutaurirana pakati peESP32 neRPi HAT. Pane kudaro, unofanira mepu IO16 seRx uye IO15 seTx pasoftware sezvakatsanangurwa muchikamu cheSoftware chebhuku rino.
• Onawo chikamu chedu pane Serial (UART) Chirongwa.

Software

• Mune zvinotevera, isu tichatsanangura muchidimbu zvakakosha zvakanyanya hurongwa hwe espBerry. Sezvambotaurwa mubhuku rino revashandisi, tichawedzera mareferensi epamhepo patinoona kuti rumwe ruzivo rwakakosha.
• Kune zvakawanda, maoko-pane chirongwa sampngationei zvedu ESP32 Programming Tips.
• Mukuwedzera, kune akawanda exampzvishoma zve ESP32 kuronga mabhuku, izvo zvakakodzera mari.
• Nekudaro, isu tinokurudzira zvikuru kushandisa Electronic Projects ine ESP8266 uye ESP32, kunyanya kune yako isina waya application mapurojekiti. Hongu, mabhuku akawanda akanaka uye zviwanikwa zvepamhepo zvepamhepo zviripo mazuva ano, asi iri ndiro bhuku ratiri kushandisa. Yakaita kuti maitiro edu kuBluetooth, BLE, uye WIFI kuve nemhepo. Kugadzira mawaya maapplication pasina matambudziko kwainakidza, uye isu tinoagovera pane yedu web site.

  

Kuisa uye Kugadzirira iyo Arduino IDE

• Yese programming yedu sampLes akagadzirwa achishandisa Arduino IDE (Integrated Development Environment) nekuda kwekureruka kwayo kwekuisa uye kushandiswa. Uyezve, kune zviuru zveArduino sketches inowanikwa online yeESP32.
• Kuisa, tevera matanho aya:
  • Danho 1: Nhanho yekutanga ingave yekurodha nekuisa iyo Arduino IDE. Izvi zvinogona kuitwa zviri nyore nekutevera chinongedzo https://www.arduino.cc/en/Main/Software uye kurodha IDE mahara. Kana uchitova nayo, ita shuwa kuti une yazvino vhezheni.
  • Danho 2: Kana yangoiswa, vhura iyo Arduino IDE, uye enda ku Files -> Zvaunofarira kuvhura hwindo rezvaunofarira uye tsvaga iyo "Yakawedzera Mabhodhi Maneja URLs:” sezvinoratidzwa pazasi:

    

    • Bhokisi remavara rinogona kunge risina chinhu kana kuti rine zvimwe URL kana wakambozvishandisa kune rimwe bhodhi. Kana isina chinhu, ingoisa pasi apa URL mubhokisi rezvinyorwa.
      https://dl.espressif.com/dl/package_esp32_index.json
    • Kana iyo text box yatova nezvimwe URL wedzera izvi URL kwairi, patsanura zvese nekoma (,). Yedu yaitova naTeensy URL. Takangopinda mu URL ndokuwedzera koma.
    • Kana wapedza, tinya OK uye hwindo rinonyangarika.
  • Danho 3: Enda kune Zvishandiso -> Mabhodhi -> Mamaneja eBoard kuvhura iyo Board maneja hwindo uye tsvaga ESP32. Kana iyo URL yakanamirwa nemazvo hwindo rako rinofanira kuwana pazasi chidzitiro neInstall bhatani, ingobaya pakanzi Isa bhatani uye bhodhi rako rinofanira kuiswa.

    
    Iyo skrini iri pamusoro inoratidza iyo ESP32 mushure mekunge yaiswa.

  • Danho 4: Usati watanga hurongwa, unofanira kuseta sarudza yakakodzera ESP32 hardware (kune akawanda sarudzo). Enda kune Zvishandiso -> Mabhodhi uye sarudza ESP32 Dev Module sezvakaratidzwa pano:

    

  • Danho 5: Vhura maneja wemudziyo uye tarisa kuti ndeipi COM port yako ESP32 yakabatana.

    

• Paunenge uchishandisa espBerry, tsvaga iyo Silicon Labs CP210x USB kuUART Bridge. Mukugadzirisa kwedu inoratidza COM4. Dzokera kuArduino IDE uye pasi peZvishandiso -> Port, sarudza Port kune iyo ESP yako yakabatana.

  

• Kana iwe uri wekutanga neArduino IDE, ndapota tarisa kune Kushandisa iyo Arduino Software (IDE).

SPI Port Programming

• Zvinotevera zvinomiririra pfupi pfupiview yeSPI programming. SPI programming haisi nyore, asi pese patinotanga chirongwa chitsva, tinotarisa kodhi online (semuenzaniso, github.com).
• Semuyenzaniso, kuronga MCP2515 CAN controller, tiri kushandisa shanduro yakagadziridzwa yeMCP_CAN Library yeArduino naCory Fowler, kureva kuti, tiri kushandisa ruzivo rwake nesimba reprojekti yedu.
• Zvakangodaro, zvakakodzera kushandisa nguva kuti unzwisise SPI programming padanho rekutanga. Semuenzaniso, iyo espBerry ine zvikwangwani zveSPI zvakamisikidzwa sezvinoratidzwa pano:

  

• Aya marongero anofanirwa kuiswa mune iyo application kodhi. Ndokumbira utarise kune zvinotevera zviwanikwa kuti udzidze zvakawanda nezveSPI programming neESP32:
  • ESP32 SPI Kukurukurirana: Seta Pini, Multiple Bhazi Interfaces, uye Peripherals…
  • Maitiro ekushandisa SPI neESP32 uye Arduino…

Serial Port (UART) Chirongwa

• Pa espBerry, takapa IO15 seRx uye IO16 seTx, iyo yakabatana neGPIO16 uye GPIO20 pane 40-pini musoro.
• Isu takasarudza kusashandisa yakajairwa RX/TX (GPIO3/GPIO1) masiginecha paESP32 DevKit, sezvo achiwanzo shandiswa pakuedza maprints kuburikidza neSerial Monitor yeArduino IDE. Izvi zvinogona kukanganisa kutaurirana pakati peESP32 neRPi HAT. Pane kudaro, iwe unofanirwa mepu IO16 seRx uye IO15 seTx pasoftware.

  

• Iyo kodhi iri pamusoro inomiririra application exampuye kushandisa Serial1.
• Paunenge uchishanda neESP32 pasi peArduino IDE, uchaona kuti murairo weSerial unoshanda zvakanaka asi Serial1 uye Serial2 hazviite. Iyo ESP32 ine matatu Hardware serial ports anogona kumepu kunenge chero ipini. Kuti uwane Serial1 uye Serial2 kushanda, unofanirwa kusanganisira iyo HardwareSerial kirasi. Sechirevo, ona ESP32, Arduino uye 3 Hardware Serial Ports.
• Onawo yedu post espBerry Project: ESP32 ine CH9102F USB-UART Chip yeSerial Speed ​​​​kusvika ku3Mbit/s.
