StackChan is ESP32 board which based on ESP32-S3 chip, contained 2-inch TFT screen. The board is made of PC+ABC.

1.1 Ukuqulunqwa kweHardware
The hardware of CORES3: ESP32-S3 chip, TFT screen, Green LED, Button, GROVE interface, TypeC-to-USB interface, Power Management chip and battery.
ESP32-S3 The ESP32 is a dual-core system with two Harvard Architecture Xtensa LX6 CPUs. All embedded memory,external memory and peripherals are located on the data bus and/or the instruction bus of these CPUs. With some minor exceptions (see below), the address mapping of two CPUs is symmetric, meaning that they use the same addresses to access the same memory. Multiple peripherals in the system can access embeddedmemory via DMA.
TFT Screen yi 2-intshi umbala screen eqhutywa ILI9342C kunye nesisombululo 320 x 240.

INKCAZELO YOMSEBENZI
Esi sahluko sichaza i-ESP32-S3 iimodyuli ezahlukeneyo kunye nemisebenzi.
3.1.CPU NENKUMBULO
Xtensa® dual-core 32-bit LX7 microprocessor, ukuya kuma 240 MHz
- 384 KB iROM
- 512 KB SRAM
- I-16 KB SRAM kwi-RTC
- I-SPI, i-Dual SPI, i-Quad SPI, i-Octal SPI, i-QPI kunye ne-OPI ujongano oluvumela uxhulumaniso kwi-flash ezininzi kunye ne-RAM yangaphandle.
- Isilawuli seflash esine-cache siyaxhaswa
- IFlash in-Circuit Programming (ICP) iyaxhaswa
3.2.INGCACISO YOKUGCINA
3.2.1. I-Flash yangaphandle kunye ne-SRAM
I-ESP32-S3 ixhasa i-SPI, i-Dual SPI, i-Quad SPI, i-Octal SPI, i-QPI kunye ne-OPI ujongano oluvumela ukudibanisa kwi-flash yangaphandle emininzi kunye ne-RAM.
The external flash and RAM can be mapped into the CPU instruction memory space and read-only data memory space. The external RAM can also be mapped into the
CPU data memory space. ESP32-S3 supports up to 1GB of external flash and RAM, and hardware encryption/decryption based on XTS-AES to protect users’programs and data in flash and external RAM.
Ngokusebenzisa i-caches enesantya esiphezulu, i-ESP32-S3 inokuxhasa ngexesha ukuya kuthi ga:
- External flash or RAMmapped into 32 MB instruction space as individual blocks of 64 KB
- I-RAM yangaphandle ifakwe kwi-32 MB yendawo yedatha njengeebhloko ezizimeleyo ezingama-64 KB. I-8-bit, i-16-bit, i-32-bit, kunye ne-128-bit ifundeka kwaye ibhale kuxhaswa. I-flash yangaphandle inokuthi ifakwe kwi-32 MB indawo yedatha njengeebhloko ezizimeleyo ze-64 KB, kodwa zixhasa kuphela i-8-bit, i-16-bit, i-32-bit kunye ne-128-bit efundwayo.
3.3.IWOtshi yeCPU
Iwotshi yeCPU inemithombo emithathu enokubakho:
- Iwotshi yekristale engundoqo yangaphandle
- I-oscillator ye-RC ekhawulezayo yangaphakathi (ngokuqhelekileyo malunga ne-17.5 MHz, kwaye iyahlengahlengiswa)
- PLL iwotshi
Usetyenziso lunokukhetha umthombo wewotshi kwiiwotshi ezintathu ezingentla.
The selected clock source drives the
CPU clock directly, or after division, depending on the application. Once the CPU is reset, the default clock source would be the external main crystal clock divided by 2.
3.4.RTC AND LOWPOWER MANAGEMENT
Ngokusebenzisa itekhnoloji yolawulo lwamandla oluphezulu, i-ESP32-S3 inokutshintsha phakathi kweendlela ezahlukeneyo zamandla. (jonga itheyibhile1).
- Imowudi esebenzayo: I-CPU kunye nerediyo ye-chip ivuliwe. Itshiphu ingafumana, idlulise, okanye imamele.
- Imowudi yokulala yeModem: I-CPU iyasebenza kwaye isantya sewotshi sinokuncitshiswa. I-wireless baseband kunye nerediyo zivaliwe, kodwa uqhagamshelwano olungenazingcingo lunokuhlala lusebenza.
- Lightsleep mode: The CPU is paused. The RTC peripherals, as well as the ULP coprocessor can be woken up periodically by the timer.
Any wake-up events (MAC, host, RTC timer, or external interrupts) will wake up the chip. Wireless connection can remain active. Users can optionally decide what peripherals to shut down/keep on (refer to Figure 1), for power-saving purpose. - Imowudi yobuthongo obunzulu: I-CPU kunye neeperipherals ezininzi zinikwe amandla.
Only the RTC memory is powered on and RTC peripherals are optional. Wi-Fi connection data are stored in the RTC memory. The
ULP coprocessor iyasebenza.
