Imaniwali yosebenzisayo

Uhlaka

I-AtomS3 iyibhodi yokuthuthukisa esekelwe ku-chip ye-ESP32-S3 futhi ihlanganisa isikrini esingu-0.85 “TFT. Ibhodi lifakwe izinkinobho ezimbili nezimbobo ze-USB-C, ngaphezu kwe-WS2812LED kanye ne-antenna engu-2.4g.

1.1 Ukwakhiwa kwe-Hardware
Ihadiwe ye-AtomS3: I-chip ye-ESP32-S3, isibonisi se-TFT, i-LED yombala, izinkinobho, Y8089DCDC. I-Esp32-s3 iyi-chip eyodwa ehlanganiswe ne-2.4ghz Wi-Fi ne-Bluetooth (LE), enemodi ye-Long Range. I-Esp32-s3 ifakwe i-Xtensa® 32-bit LX7 dual-core processor, efika ku-240mhz, eyakhelwe ngaphakathi engu-512KB SRAM (TCM), amaphinikhodi we-GPIO ahlelekayo angu-45, nezindawo zokuxhumana ezinothile. I-Esp32-s3 isekela umthamo omkhulu we-octal SPI Flash enesivinini esikhulu ne-off-chip RAM, futhi isekela ukugcinwa kwedatha okulungiselelwe umsebenzisi kanye nokugcinwa kwesikhashana kweziyalezo.

Isikrini se-TFT siyisikrini esingu-0.85 “esinikwe amandla yi-GC9107 ngokulungiswa okungu-128 x 128. Ivolumu esebenzayotagi-e range 2.4-3.3V, izinga lokushisa lokusebenza i-0-40°C.
I-chip yokuphatha amandla yi-SY8089 ye-Silergy. Ukusebenza voltagi-e range ingu-2.7V-5.5V, yamanje yokushaja ngu-2A. I-AtomS3 iza nakho konke okudingayo ukuze uhlele i-ESP32, konke okudingeka ukwenze futhi ukuthuthukise

INCAZELO YOMSEBENZI

Lesi sahluko sichaza amamojula nemisebenzi ehlukahlukene ye-ESP32-S3.

3.1.CPU NEMEMORY
I-Xtensai, i-dual core 32-bit LX7 microprocessormp ukuya ku-240 MHz

• 384 K8 ROM
• 512 K8 SRAM
• 16 KB SRAM ku-RTC
• SP/, _Okukabili I-SP/, i-Quad SPI Octal SRI OP' ne-OP/ izixhumanisi ezivumela ukuxhumeka ku-flash eminingi kanye ne-RAM yangaphandle
• Isilawuli se-flash esinenqolobane siyasekelwa
• I-Flash in-Circuit Programming (/CP) iyasekelwa

3.2 INCAZELO YESOLO
3.2.1.I-Flash yangaphandle kanye ne-RAM
I-ESP32-S3 isekela i-SPI, i-Dual SPI, i-Quad SPI, i-Octal SPI, i-QM ne-OPI interfaces evumela ukuxhumeka ku-flash yangaphandle eminingi kanye ne-RAM.
I-flash yangaphandle kanye ne-RAM kungadwetshwa kusikhala senkumbulo yeziqondiso ze-CPU kanye nesikhala sememori yedatha yokufunda kuphela. I-RAM yangaphandle ingaphinda ifakwe kumephu yesikhala sememori yedatha ye-CPU. I-ESP32-S3 isekela kufikela kokungu-168 kwe-flash yangaphandle kanye ne-RAM, kanye ne-hardware encryption/decryption esekelwe ku-XTS-AES ukuvikela izinhlelo zabasebenzisi kanye nedatha ku-flash kanye ne-RAM yangaphandle.
Ngokusebenzisa ama-caches anesivinini esikhulu, i-ESP32-S3 ingasekela ngesikhathi kufika:

• I-flash yangaphandle noma i-RAM efakwe kumephu endaweni yokufundisa engu-32 MB njengamabhulokhi angawodwana angu-64 KB
• I-RAM yangaphandle ifakwe kumephu yesikhala sedatha esingu-32 MB njengamabhulokhi angawodwana angu-64 KB. I-8-bit, 16-bit, 32-bit, kanye ne-128-bit efundwayo futhi ibhale ukuthi I-flash yangaphandle ingaphinda ifakwe kumephu yesikhala sedatha esingu-32 MB njengamabhulokhi angawodwana angu-64 KB, kodwa asekela kuphela i-8-bit, 16-bit, 32 -bit kanye ne-128-bit ifundwe.

3.3.IWASHI LE-CPU
Iwashi le-CPU linemithombo emithathu engaba khona:

• Iwashi lekristalu elikhulu langaphandle
• I-oscillator ye-RC esheshayo yangaphakathi (imvamisa icishe ibe ngu-17.5 MHz, futhi iyalungiseka)
• Iwashi le-PLL

Uhlelo lokusebenza lungakhetha umthombo wewashi emawashini amathathu angenhla. Umthombo wewashi okhethiwe ushayela iwashi le-CPU ngokuqondile, noma ngemva kokuhlukaniswa, kuye ngohlelo lokusebenza. Uma i-CPU isisethwe kabusha, umthombo wewashi ozenzakalelayo uzoba iwashi lekristalu eliyinhloko langaphandle elihlukaniswe ngo-2.

3.4. UKUPHATHWA KWE-RTC KANYE NAMANDLA APHANSI
Ngokusetshenziswa kobuchwepheshe bokuphatha amandla obuthuthukisiwe, i-ESP32-S3 ingashintsha phakathi kwezindlela zamandla ezihlukene. (bheka ithebula1).

• Imodi esebenzayo: I-CPU nerediyo ye-chip ivuliwe. I-chip ingathola, idlulise, noma ilalele.
• Imodi yokulala ye-Modems: I-CPU iyasebenza futhi isivinini sewashi singancishiswa. I-baseband engenantambo nomsakazo kuvaliwe, kodwa ukuxhumana okungenantambo kungahlala kusebenza.
• Imodi yokulala okukhanyayo: I-CPU imisiwe. Ama-peripherals e-RTC, kanye ne-ULP coprocessor ingavuswa ngezikhathi ezithile isibali sikhathi. Noma yimiphi imicimbi yokuvuka (i-MAC, isibali sikhathi se-RTC, noma iziphazamiso zangaphandle) izovusa i-chip. Ukuxhumeka okungenantambo kungahlala kusebenza. Abasebenzisi banganquma ngokuzikhethela ukuthi yimaphi amapheripheral okufanele avale/aqhubeke (bheka Umfanekiso 1), ngenjongo yokonga amandla.
• Imodi yokulala okujulile: I-CPU kanye nama-peripherals amaningi anikwa amandla. Imemori ye-RTC kuphela evuliwe futhi ama-peripheral e-RTC ayidatha yoxhumano lwe-Wi-Fi egcinwa kumemori ye-RTC. I-coprocessor ye-ULP iyasebenza

Isitatimende se-FCC
Noma yiziphi Izinguquko noma ukuguqulwa okungagunyazwanga ngokucacile yinhlangano enesibopho sokuthobela imithetho kungasusa igunya lomsebenzisi lokusebenzisa okokusebenza. Le divayisi ithobela ingxenye 15 yemithetho ye-FCC. Ukusebenza kungaphansi kwezimo ezimbili ezilandelayo: (1) Lolu cingo angeke lubangele ukuphazamiseka okuyingozi, futhi (2) Lolu cingo kufanele lwamukele noma yikuphi ukuphazamiseka okutholiwe, okuhlanganisa ukuphazamiseka okungase kubangele ukusebenza okungafuneki.
Isitatimende Sokuchayeka Kwi-FCC Radiation: Lesi sixhobo sithobela imikhawulo yokuchayeka emisebeni ye-FCC ebekwe endaweni engalawuleki .Lokhu okokusebenza kufanele kufakwe futhi kusetshenziswe ngebanga elincane elingu-20cm phakathi kwerediyetha nomzimba wakho.
Qaphela : Lesi sixhobo sihloliwe futhi kwatholakala ukuthi sithobela imikhawulo yedivayisi yedijithali Yekilasi B, ngokususelwe engxenyeni 15 yeMithetho ye-FCC. Le mikhawulo iklanyelwe ukuhlinzeka ngokuvikeleka okufanele ekuphazanyisweni okuyingozi ekufakweni kwendawo yokuhlala. Lesi sixhobo sikhiqiza, sisebenzisa futhi singakhipha amandla efrikhwensi yomsakazo futhi, uma singafakiwe futhi sisetshenziswa ngokuhambisana nemiyalelo, singadala ukuphazamiseka okuyingozi ezokuxhumana ngomsakazo. Nokho, asikho isiqinisekiso sokuthi ukuphazamiseka ngeke kwenzeke ekufakweni okuthile.
