Kusunga Pini
ESP32 ine mapini mashanu ekusunga:

  • MTDI
  • GPIO0
  • GPIO2
  • MTDO
  • GPIO5

Iyo software inogona kuverenga kukosha kweaya mabhiti mashanu kubva murejista "GPIO_STRAPPING". Munguva ye chip's system reset kuburitswa (simba-on-reset, RTC watchdog reset uye brownout reset), machira emapini ekusunga s.ampuye voltage nhanho semabhati ekusunga e”0” kana “1”, wobata mabhiti aya kusvikira chip yadzikiswa kana kuvharwa. Mabhandi ekusunga anogadzirisa bhoti yemudziyo, iyo inoshanda voltage yeVDD_SDIO nemamwe masisitimu ekutanga. Imwe neimwe pini yekusungirira yakabatana kune yayo yemukati kudhonza-kumusoro / kudhonza-pasi panguva ye chip reset. Nekuda kweizvozvo, kana pini yekusungirira isina kubatanidzwa kana iyo yakabatana yekunze dunhu iri yakakwira-impedance, iyo yemukati isina kusimba kudhonza-kumusoro / kudhonzera-pasi ichaona iyo yekusarudzika yekupinza nhanho yepini dzekusunga. Kuti uchinje maitiro ekusungirira, vashandisi vanogona kuisa iyo yekunze kudhonza-pasi / kudhonza-kumusoro kuramba, kana kushandisa iyo inotambira MCU's GPIOs kudzora vol.tage nhanho yemapini aya paunenge uchibatidza paESP32. Mushure mekugadzirisazve kuburitswa, mapini ekusunga anoshanda seakajairika-basa mapini. Tarisa kuTafura 2 kune yakadzama bhutsu-modhi yekumisikidza nekusunga mapini.

Cherechedza: 

  • Firmware inogona kugadzirisa mabheti ekunyoresa kuti achinje marongero e "Voltage yeInternal LDO (VDD_SDIO)" uye "Nguva yeSDIO Slave" mushure mekutanga.
  • Iyo yemukati yekudhonza-up resistor (R9) yeMTDI haina kugarwa mumodule, sezvo iyo flash uye SRAM muESP32 inongotsigira simba vol.tage ye3.3 V (yakabuda neVDD_SDIO)

Tsanangudzo Yekushanda

Ichi chitsauko chinotsanangura mamodule uye mabasa akabatanidzwa muESP32.

CPU uye Yemukati Memory
ESP32 ine maviri-akaderera-simba Xtensa® 32-bit LX6 microprocessors. Iyo yemukati ndangariro inosanganisira:

  • 448 KB yeROM yekubhoti uye yakakosha mabasa.
  • 520 KB ye-on-chip SRAM yedata uye mirairo.
  • 8 KB yeSRAM muRTC, inodaidzwa kuti RTC FAST Memory uye inogona kushandiswa kuchengetedza data; inowanikwa neCPU huru panguva yeRTC Boot kubva kuDeep-sleep mode.
  • 8 KB yeSRAM muRTC, inodaidzwa kuti RTC SLOW Memory uye inogona kuwanikwa neco-processor panguva yeKurara-Kurara modhi.
  • 1 Kbit ye ​​eFuse: 256 bits inoshandiswa kune iyo system (MAC kero uye chip configuration) uye asara 768 bits akachengeterwa kushandiswa kwevatengi, kusanganisira flash-encryption uye chip-ID.

Kunze Flash uye SRAM
ESP32 inotsigira akawanda ekunze QSPI flash uye SRAM machipisi. ESP32 inotsigirawo hardware encryption/decryption yakavakirwa paAES kudzivirira zvirongwa zvevagadziri uye data muFlash.

ESP32 inogona kuwana yekunze QSPI flash uye SRAM kuburikidza nepamusoro-kumhanya cache.

  • Iyo yekunze flash inogona kumepuwa muCPU yekuraira ndangariro nzvimbo uye yekuverenga-chete ndangariro nzvimbo panguva imwe chete.
    • Kana mwenje wekunze wakaiswa muCPU yekuraira ndangariro nzvimbo, inosvika 11 MB + 248 KB inogona kumepuwa panguva. Ziva kuti kana anopfuura 3 MB + 248 KB akaiswa mepu, cache performance ichadzikiswa nekuda kwekufungidzira kuverengwa neCPU.
    • Kana flash yekunze ikaiswa mepu yekuverenga-chete data memory space, inosvika 4 MB inogona kumepuwa panguva. 8-bit, 16-bit uye 32-bit kuverenga zvinotsigirwa.
  • Yekunze SRAM inogona kuiswa muCPU data memory space. Kusvika ku4 MB inogona kumepuwa panguva. 8-bit, 16-bit uye 32-bit inoverenga uye inonyora inotsigirwa.

ESP32 inobatanidza 8 MB SPI flash uye 8 MB PSRAM kune imwe nzvimbo yekuyeuka.

Crystal oscillators
Iyo module inoshandisa 40-MHz crystal oscillator.

RTC uye Yakaderera-Simba Management
Nekushandiswa kwehunyanzvi hwekugadzirisa masimba emagetsi, ESP32 inogona kushandura pakati pemamodhi emagetsi akasiyana.
