M5STACK ESP32 CORE2 IoT Manual Mai amfani Kit Development

1. BAYANI

M5Stick CORE2 jirgi ne na ESP32 wanda ya dogara da guntu ESP32-D0WDQ6-V3, mai dauke da allon TFT mai inci 2. An yi allo da PC+ABC.

1.1 Haɗin Hardware

Kayan aikin CORE2: ESP32-D0WDQ6-V3 guntu, allon TFT, LED Green, Button, GROVE interface, Type.C-to-USB interface, guntu Gudanar da wutar lantarki da baturi.
ESP32-D0WDQ6-V3 ESP32 tsarin dual-core ne tare da Harvard Architecture Tense LX6 CPUs guda biyu. Duk ƙwaƙwalwar ajiya, ƙwaƙwalwar ajiya ta waje da maɓalli suna kan bas ɗin bayanai da/ko bas ɗin koyarwa na waɗannan CPUs. Tare da wasu ƙananan keɓanta (duba ƙasa), taswirar adreshin na CPUs biyu yana da ma'ana, ma'ana suna amfani da adireshi iri ɗaya don samun damar ƙwaƙwalwar ajiya iri ɗaya. Maɓallai da yawa a cikin tsarin na iya samun damar ƙwaƙwalwar ajiya ta hanyar DMA.

Allon TFT shine allo mai launi 2-inch wanda aka kora ILI9342C tare da ƙudurin 320 x 240.
Ƙa'idar aikitage kewayon shine 2.6 ~ 3.3V, kewayon zafin aiki shine -25 ~ 55 ° C.
Guntu Gudanar da Wuta shine X-Powers's AXP192. Ayyukan aiki voltage kewayon shine 2.9V ~ 6.3V kuma cajin halin yanzu shine 1.4A.
CORE2 yana ba da ESP32 tare da duk abin da ake buƙata don shirye-shirye, duk abin da ake buƙata don aiki da haɓakawa

3. BAYANIN AIKI

Wannan babin yana bayyana ESP32-D0WDQ6-V3 kayayyaki da ayyuka daban-daban.

3.1. CPU DA ƙwaƙwalwar ajiya

Xtensa® guda-/dual-core32-bitLX6microprocessor(s), har zuwa600MIPS (200MIPSforESP32-S0WD/ESP32-U4WDH, 400 MIPS don ESP32-D2WD):

• 448 KB ROM
• 520 KB SRAM
• 16 KB SRAM a cikin RTC
• QSPI tana goyan bayan kwakwalwan walƙiya/SRAM da yawa

3.2. BAYANIN ARZIKI

3.2.1.Flash na waje da SRAM

ESP32 yana goyan bayan filasha QSPI na waje da yawa da ƙwaƙwalwar samun damar bazuwar (SRAM), tare da ɓoye bayanan AES na tushen hardware don kare shirye-shiryen mai amfani da bayanai.

• ESP32 samun damar QSPI Flash na waje da SRAM ta caching. Har zuwa 16 MB sarari code Flash na waje an tsara shi cikin CPU, yana goyan bayan samun damar 8-bit, 16-bit da 32-bit, kuma yana iya aiwatar da lamba.
• Har zuwa 8 MB na waje Flash da SRAM da aka tsara zuwa sararin bayanan CPU, tallafi don samun damar 8-bit, 16-bit da 32-bit. Flash yana tallafawa ayyukan karantawa kawai, SRAM yana goyan bayan ayyukan karantawa da rubutawa.

3.3. CRYSTAL

Na waje 2 MHz ~ 60 MHz crystal oscillator (40 MHz kawai don Wi-Fi / BT ayyuka)

3.4. Gudanar da RTC DA KARANCIN CIN WUTA

ESP32 yana amfani da ingantattun dabarun sarrafa wutar lantarki na iya canzawa tsakanin hanyoyin ceton wuta daban-daban. (Duba Table 5).

• Yanayin ajiyar wuta
  - Yanayin aiki: guntu RF yana aiki. Chip na iya karɓa da watsa siginar ƙara.
  - Yanayin barci-modem: CPU na iya aiki, ana iya daidaita agogo. Wi-Fi / Bluetooth baseband da RF
  - Yanayin barci mai haske: An dakatar da CPU. RTC da ƙwaƙwalwar ajiya da na'urorin haɗin gwiwar ULP. Duk wani taron farkawa (MAC, mai masaukin baki, mai ƙidayar lokaci na RTC ko katsewar waje) zai farka guntu. - Yanayin barci mai zurfi: kawai ƙwaƙwalwar RTC da abubuwan da ke cikin yanayin aiki. WiFi da bayanan haɗin Bluetooth da aka adana a cikin RTC. ULP coprocessor na iya aiki. - Yanayin Hibernation: 8 MHz oscillator da ginanniyar coprocessor ULP an kashe su. Ƙwaƙwalwar RTC don maido da wutar lantarki ya katse. Mai ƙidayar agogon RTC guda ɗaya kawai wanda ke kan jinkirin agogo da wasu RTC GPIO a wurin aiki. Agogon RTC RTC ko mai ƙidayar lokaci na iya farkawa daga yanayin Hibernation na GPIO.
• Yanayin barci mai zurfi
  - Yanayin barci mai alaƙa: yanayin ajiyar wutar lantarki yana canzawa tsakanin Active, Modem-barci, yanayin barci mai haske. CPU, Wi-Fi, Bluetooth, da tazarar saiti na rediyo da za a tada, don tabbatar da haɗin Wi-Fi / Bluetooth.
  - Hanyoyin saka idanu na firikwensin ƙananan ƙarfi: babban tsarin shine yanayin barci mai zurfi, ULP coprocessor yana buɗewa ko rufe lokaci-lokaci don auna bayanan firikwensin. Na'urar firikwensin yana auna bayanai, ULP coprocessor ya yanke shawarar ko zai farka babban tsarin.
