Malingaliro a kampani COREINK ndi bolodi la ESP32 lomwe limachokera ku gawo la ESP32-PICO-D4, lomwe lili ndi 1.54-inch eINK. Gululo limapangidwa ndi PC + ABC.

1.1 Mapangidwe a Hardware

Zida za hardware za Malingaliro a kampani COREINK: ESP32-PICO-D4 chip, eLNK, LED, Button, GROVE mawonekedwe, TypeC-to-USB mawonekedwe, RTC, Power Management Chip batire.

ESP32- PICO-D4 ndi gawo la System-in-Package (SiP) lomwe lazikidwa pa ESP32, lomwe limapereka magwiridwe antchito athunthu a Wi-Fi ndi Bluetooth. Module imaphatikiza kung'anima kwa 4-MB SPI. ESP32-PICO-D4 imaphatikiza zida zonse zotumphukira mosasunthika, kuphatikiza crystal oscillator, flash, capacitor fyuluta ndi maulalo ofananira a RF mu phukusi limodzi.

1.54 "E-Paper Display

Chiwonetserocho ndi chowonetsera cha TFT chogwiritsa ntchito matrix electrophoretic, chokhala ndi mawonekedwe ndi mawonekedwe amtundu wa ma reference system. The 1. 54 ” malo ogwirira ntchito ali ndi ma pixel 200 × 200, ndipo ali ndi mawonekedwe oyera / akuda a 1-bit. Dera lophatikizika lili ndi buffer pachipata, buffer gwero, mawonekedwe, malingaliro owongolera nthawi, oscillator, DC-DC, SRAM, LUT, VCOMndi malire amaperekedwa ndi gulu lililonse.

PIN DESCRIPTION

2.1.USB INTERFACE

Malingaliro a kampani COREINK Kusintha kwa mtundu wa C mtundu wa USB mawonekedwe, kuthandizira njira yolumikizirana yokhazikika ya USB2.0.

2.2.GROVE INTERFACE

4p phula lotayidwa la 2.0mm Malingaliro a kampani COREINK GROVE interfaces, mawaya amkati ndi GND, 5V, GPIO4, GPIO13 yolumikizidwa.

FUNCTIONAL DESCRIPTION

Mutuwu ukufotokoza za ESP32-PICO-D4 ma module ndi ntchito zosiyanasiyana.

3.1.CPU NDI MEMORY

ESP32-PICO-D4 ili ndi Xtensa® 32-bit LX6 MCU ziwiri zamphamvu zochepa. Memory on-chip yomwe ili ndi:

448-KB ya ROM, ndipo pulogalamuyi imayambira kuyimba kwa kernel
Pa malangizo a 520 KB ndi chipangizo chosungira deta SRAM (kuphatikizapo flash memory 8 KB RTC)

mode, ndi kusunga deta yofikiridwa ndi CPU yayikulu
Memory yapang'onopang'ono ya RTC, ya 8 KB SRAM, imatha kupezeka ndi coprocessor mu Deepsleep mode

Ya 1 kbit ya eFuse, yomwe ndi 256 bit system-specific (MAC address ndi chip set); 768 yotsalayo yosungidwa pulogalamu ya ogwiritsa ntchito, pulogalamu ya Flash iyi imaphatikizapo kubisa ndi ID ya chip

3.2.KUTENGA ZOSANGALATSA

3.2.1.Kunyezimira Kwakunja ndi SRAM

ESP32 imathandizira kung'anima kwa QSPI yakunja ndi kukumbukira kosasintha kosasintha (SRAM), yokhala ndi encryption yochokera ku hardware ya AES kuteteza mapulogalamu ndi deta.

ESP32 ipezani QSPI Flash yakunja ndi SRAM posungira. Malo ofikira 16 MB akunja a Flash code amajambulidwa mu CPU, amathandizira 8-bit, 16-bit ndi 32 bit, ndipo amatha kugwiritsa ntchito ma code.

Kufikira 8 MB yakunja Kung'anima ndi SRAM yojambulidwa ku malo a data a CPU, chithandizo cha 8-bit, 16-bit ndi 32-bit. Flash imathandizira ntchito zowerengera zokha, SRAM imathandizira kuwerenga ndi kulemba ntchito.

ESP32-PICO-D4 4 MB ya Integrated SPI Flash, code ikhoza kujambulidwa mu CPU space, chithandizo cha 8-bit, 16-bit ndi 32-bit, ndipo ikhoza kuyika code. Pini GPIO6 ESP32 ya, GPIO7, GPIO8, GPIO9, GPIO10 ndi GPIO11 polumikiza module Integrated SPI Flash, yosavomerezeka pazinthu zina.

3.3.CHIKRISTU

ESP32-PICO-D4 imaphatikiza 40 MHz crystal oscillator.

3.4.RTC MANAGEMENT NDI KUGWIRITSA NTCHITO MPHAMVU YOCHEPA

ESP32 imagwiritsa ntchito njira zapamwamba zowongolera mphamvu zitha kusinthidwa pakati pa mitundu yosiyanasiyana yosungira mphamvu. (Onani Gulu 5).

Njira yopulumutsira mphamvu
- Njira Yogwira: Chip cha RF chikugwira ntchito. Chip chikhoza kulandira ndi kutumiza chizindikiro chomveka.
- Magonedwe a Modem: CPU imatha kuthamanga, koloko ikhoza kukonzedwa. Wi-Fi / Bluetooth baseband ndi RF
- Magonedwe opepuka: CPU idayimitsidwa. RTC ndi kukumbukira ndi zotumphukira ULP coprocessor ntchito. Chochitika chilichonse chodzuka (MAC, host host, RTC chowerengera kapena kusokoneza kunja) chidzadzutsa chip.
- Kugona kwakukulu: kukumbukira kwa RTC kokha ndi zotumphukira zomwe zimagwira ntchito. Zolumikizana za WiFi ndi Bluetooth zosungidwa mu RTC. ULP coprocessor ikhoza kugwira ntchito.
- Mayendedwe a Hibernation: 8 MHz oscillator ndi coprocessor ULP yolumikizidwa ndizozimitsa. Memory ya RTC yobwezeretsa magetsi yatha. Wotchi imodzi yokha ya RTC yomwe ili pawotchi yapang'onopang'ono ndi RTC GPIO ina kuntchito. Wotchi ya RTC RTC kapena chowerengera imatha kudzuka panjira ya GPIO Hibernation.
Mawonekedwe akugona kwambiri
- Kugona kofananira: njira yosungira mphamvu yosinthira pakati pa Active, Modem-kugona, Kuwala-kugona mode. CPU, Wi-Fi, Bluetooth, ndi nthawi yokhazikitsidwa ndi wailesi kuti adzutse, kuonetsetsa kulumikizana kwa Wi-Fi / Bluetooth.
- Njira zowunikira za Ultra Low-power sensor: dongosolo lalikulu ndi Deep-sleep mode, ULP coprocessor imatsegulidwa nthawi ndi nthawi kapena kutsekedwa kuti ayeze deta ya sensor.
Sensa imayesa deta, ULP coprocessor imasankha kudzutsa dongosolo lalikulu.

Ntchito m'njira zosiyanasiyana zogwiritsira ntchito mphamvu: TABLE 5

MAKHALIDWE AMAGAKA

Gulu 8: Kuchepetsa zikhalidwe

VIO kumalo operekera magetsi, Onani Zowonjezera Zachidziwitso za ESP32 IO_MUX, monga SD_CLK ya Magetsi a VDD_SDIO.

Dinani ndikugwira batani la mphamvu yam'mbali kwa masekondi awiri kuti muyambitse chipangizocho.Dinani ndikugwira kwa masekondi oposa 6 kuti muzimitse chipangizocho. Sinthani mawonekedwe a chithunzi kudzera pawindo la Home, ndipo avatar yomwe ingapezeke kudzera mu kamera ikuwonetsedwa pawindo la tft.Chingwe cha USB chiyenera kulumikizidwa pamene chikugwira ntchito, ndipo batri ya lithiamu imagwiritsidwa ntchito posungirako nthawi yochepa kuti iteteze mphamvu. kulephera.

Chithunzi cha FCC
Kusintha kulikonse kapena kusintha komwe sikunavomerezedwe ndi gulu lomwe limayang'anira kutsata kungathe kulepheretsa wogwiritsa ntchito kugwiritsa ntchito zidazo.

Chipangizochi chikugwirizana ndi gawo 15 la Malamulo a FCC. Kugwira ntchito kumadalira zinthu ziwiri izi:
(1) Chipangizochi sichikhoza kuyambitsa kusokoneza kovulaza, ndi
(2) Chipangizochi chiyenera kuvomereza kusokoneza kulikonse komwe kumalandira, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosayenera.

Zindikirani:
Zipangizozi zayesedwa ndipo zapezeka kuti zikugwirizana ndi malire a chipangizo cha digito cha Gulu B, motsatira gawo 15 la Malamulo a FCC. Malire awa adapangidwa kuti apereke chitetezo chokwanira ku kusokoneza koyipa pakukhazikitsa nyumba. Chipangizochi chimapanga, chimagwiritsa ntchito komanso chimatha kuwunikira mphamvu zamawayilesi ndipo, ngati sichinayikidwe ndikugwiritsidwa ntchito motsatira malangizo, chikhoza kuyambitsa kusokoneza kwa mawayilesi. Komabe, palibe chitsimikizo kuti kusokoneza sikudzachitika mu unsembe winawake. Ngati chida ichi chikuyambitsa kusokoneza koyipa kwa wailesi kapena kulandila wailesi yakanema, komwe kungadziwike ndikuzimitsa ndi kuyatsa zida, wogwiritsa ntchitoyo akulimbikitsidwa kuyesa kusokoneza ndi chimodzi kapena zingapo mwa izi:

-Sunganitsanso kapena sinthani mlongoti womwe ukulandira.
-Onjezani kulekanitsa pakati pa zida ndi zolandila.
-Lumikizani zidazo kuti mutuluke pabwalo losiyana ndi lomwe wolandila amalumikizidwa.
- Funsani wogulitsa kapena wodziwa ntchito pa wailesi/TV kuti akuthandizeni.

Ndemanga ya FCC Radiation Exposure:
Chipangizochi chikugwirizana ndi malire a FCC okhudzana ndi kukhudzana ndi ma radiation omwe akhazikitsidwa kumalo osalamulirika .Chida ichi chiyenera kuikidwa ndikugwiritsidwa ntchito ndi mtunda wochepera 20cm pakati pa radiator ndi thupi lanu.
