StackChan is ESP32 board which based on ESP32-S3 chip, contained 2-inch TFT screen. The board is made of PC+ABC.
1.1 Kompożizzjoni tal-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.
TFT Screen huwa skrin bil-kulur ta '2 pulzieri misjuq ILI9342C b'riżoluzzjoni ta' 320 x 240.
Vol operattivtagIl-firxa e hija 2.6 ~ 3.3V, il-firxa tat-temperatura tax-xogħol hija -25 ~ 55°C.
Iċ-ċippa tal-Ġestjoni tal-Enerġija hija l-AXP2101 ta 'X-Powers. Il-vol operattivtagIl-firxa e hija 2.9V ~ 6.3V u l-kurrent tal-iċċarġjar huwa 1.4A.
StackChan equips ESP32 with everything needed for programming, everything needed for operation and development

DESKRIZZJONI FUNZJONALI
Dan il-kapitolu jiddeskrivi l-ESP32-S3 diversi moduli u funzjonijiet.
3.1.CPU U MEMORJA
Mikroproċessur Xtensa® dual-core 32-bit LX7, sa 240 MHz
- ROM 384 KB
- 512 KB SRAM
- 16 KB SRAM f'RTC
- SPI, Dual SPI, Quad SPI, Octal SPI, QPI u interfaces OPI li jippermettu konnessjoni għal flash multipli u RAM esterni
- Il-kontrollur tal-flash bil-cache huwa appoġġjat
- Flash in-Circuit Programming (ICP) huwa appoġġjat
3.2.DESKRIZZJONI TAL-ĦAŻNA
3.2.1. Flash Esterni u SRAM
ESP32-S3 jappoġġja interfaces SPI, Dual SPI, Quad SPI, Octal SPI, QPI u OPI li jippermettu konnessjoni għal flash u RAM multipli esterni.
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.
Permezz ta’ caches ta’ veloċità għolja, ESP32-S3 jista’ jappoġġja kull darba sa:
- External flash or RAMmapped into 32 MB instruction space as individual blocks of 64 KB
- RAM esterna mmappjata fi spazju tad-dejta ta’ 32 MB bħala blokki individwali ta’ 64 KB. Il-qari u l-kitba ta' 8-bit, 16-bit, 32-bit u 128-bit huma appoġġjati. Il-flash estern jista' wkoll jiġi mmappjat fi spazju ta' dejta ta' 32 MB bħala blokki individwali ta' 64 KB, iżda jappoġġaw biss qari ta' 8-bit, 16-bit, 32-bit u 128-bit.
3.3.ARLOĠĠ TAL-CPU
L-arloġġ tas-CPU għandu tliet sorsi possibbli:
- Arloġġ tal-kristall prinċipali estern
- Oxxillatur RC veloċi intern (tipikament madwar 17.5 MHz, u aġġustabbli)
- Arloġġ PLL
L-applikazzjoni tista 'tagħżel is-sors tal-arloġġ mit-tliet arloġġi ta' hawn fuq.
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
Bl-użu ta 'teknoloġiji avvanzati ta' ġestjoni tal-enerġija, ESP32-S3 jista 'jaqleb bejn modi ta' enerġija differenti. (ara t-tabella 1).
- Modalità attiva: CPU u radju taċ-ċippa huma mixgħula. Iċ-ċippa tista 'tirċievi, tittrasmetti, jew tisma'.
- Modalità Modemsleep: Is-CPU huwa operattiv u l-veloċità tal-arloġġ tista 'titnaqqas. Il-banda bażi bla fili u r-radju huma diżattivati, iżda l-konnessjoni bla fili tista 'tibqa' attiva.
- 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. - Modalità Deepsleep: Is-CPU u l-biċċa l-kbira tal-periferali huma mitfija.
Only the RTC memory is powered on and RTC peripherals are optional. Wi-Fi connection data are stored in the RTC memory. The
Il-koproċessur ULP huwa funzjonali.
