GARIS

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

1.1 Komposisi hardware
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.
Layar TFT nyaéta layar warna 2 inci anu didorong ILI9342C kalayan résolusi 320 x 240.
Operasi voltagrentang e nyaeta 2.6 ~ 3.3V, rentang suhu gawé téh -25 ~ 55 °C.
Chip Manajemén Daya nyaéta AXP2101 X-Powers. Operasi voltagrentang e nyaéta 2.9V ~ 6.3V sareng arus ngecas nyaéta 1.4A.
StackChan equips ESP32 with everything needed for programming, everything needed for operation and development

DESKRIPSI FUNGSIONAL

Bab ieu ngajelaskeun ESP32-S3 rupa modul jeung fungsi.
3.1.CPU jeung mémori
Xtensa® dual-core 32-bit mikroprosesor LX7, nepi ka 240 MHz

• 384 KB ROM
• 512 KB SRAM
• 16 KB SRAM di RTC
• SPI, Dual SPI, Quad SPI, Octal SPI, QPI sareng antarmuka OPI anu ngamungkinkeun sambungan kana sababaraha lampu kilat sareng RAM éksternal
• Flash controller kalawan cache dirojong
• Flash in-Circuit Programming (ICP) dirojong

3.2.DESKRIPSI PENYIMPANAN
3.2.1. Flash éksternal sareng SRAM
ESP32-S3 ngadukung SPI, Dual SPI, Quad SPI, Octal SPI, QPI sareng OPI interfaces anu ngamungkinkeun sambungan kana sababaraha lampu kilat éksternal sareng 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.
Ngaliwatan cache-speed tinggi, ESP32-S3 tiasa ngarojong sakaligus nepi ka:

• External flash or RAMmapped into 32 MB instruction space as individual blocks of 64 KB
• RAM éksternal dipetakeun kana spasi data 32 MB salaku blok individu 64 KB. 8-bit, 16-bit, 32-bit, sareng 128-bit maca sareng nyerat dirojong. Lampu kilat éksternal ogé tiasa dipetakeun kana rohangan data 32 MB salaku blok individu 64 KB, tapi ngan ukur ngadukung bacaan 8-bit, 16-bit, 32-bit sareng 128-bit.

3.3.Jam CPU
Jam CPU ngagaduhan tilu sumber anu mungkin:

• Jam kristal utama éksternal
• Osilator RC gancang internal (biasana sakitar 17.5 MHz, sareng tiasa disaluyukeun)
• jam PLL

Aplikasi tiasa milih sumber jam tina tilu jam di luhur.
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
Kalayan ngagunakeun téknologi manajemén kakuatan canggih, ESP32-S3 tiasa ngalih antara modeu kakuatan anu béda. (tingali tabél 1).

• Modeu aktip: CPU sareng radio chip diaktipkeun. Chip tiasa nampi, ngirimkeun, atanapi ngadangukeun.
• Modem modemsleep: CPU beroperasi sareng laju jam tiasa dikirangan. Baseband nirkabel sareng radio ditumpurkeun, tapi sambungan nirkabel tiasa tetep aktip.
• 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.
• Modeu Deepsleep: CPU sareng seueur periferal dipareuman.
  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 fungsina.
