StackChan is ESP32 board which based on ESP32-S3 chip, contained 2-inch TFT screen. The board is made of PC+ABC.
1.1 Cruth bathar-cruaidh
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.
Tha TFT Screen na sgrion dath 2-òirleach air a stiùireadh le ILI9342C le rùn de 320 x 240.

TUAIRISGE NA BEATHA
Tha a’ chaibideil seo a’ toirt cunntas air na diofar mhodalan agus ghnìomhan ESP32-S3.
3.1.CPU AGUS CÙRAM
Microprocessor Xtensa® dà-cridhe 32-bit LX7, suas ri 240 MHz
- 384 KB ROM
- 512 KB SRAM
- 16 KB SRAM ann an RTC
- Eadar-aghaidh SPI, SPI Dual, Quad SPI, Octal SPI, QPI agus OPI a leigeas le ceangal ri ioma-flash agus RAM taobh a-muigh
- Tha taic ri rianadair Flash le tasgadan
- Thathas a’ toirt taic do Phrògramadh In-Circuit Flash (ICP).
3.2.STORAGE TUAIRISGE
3.2.1. Flash taobh a-muigh agus SRAM
Tha ESP32-S3 a’ toirt taic do eadar-aghaidh SPI, Dual SPI, Quad SPI, Octal SPI, QPI agus OPI a leigeas le ceangal ri ioma flash taobh a-muigh agus 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.
Tro caches àrd-astar, faodaidh ESP32-S3 taic a thoirt aig àm suas gu:
- External flash or RAMmapped into 32 MB instruction space as individual blocks of 64 KB
- RAM taobh a-muigh air a mhapadh ann an àite dàta 32 MB mar bhlocaichean fa leth de 64 KB. Tha taic ri leughadh is sgrìobhadh 8-bit, 16-bit, 32-bit, agus 128-bit. Faodar flash taobh a-muigh a mhapadh cuideachd ann an àite dàta 32 MB mar bhlocaichean fa leth de 64 KB, ach dìreach a ’toirt taic do leughaidhean 8-bit, 16-bit, 32-bit agus 128-bit.
3.3.CPU CLOC
Tha trì stòran comasach aig a’ ghleoc CPU:
- Prìomh ghleoc criostail taobh a-muigh
- Oscillator RC luath a-staigh (mar as trice timcheall air 17.5 MHz, agus comasach atharrachadh)
- uaireadair PLL
Faodaidh an aplacaid stòr a’ ghleoc a thaghadh bho na trì gleocaichean gu h-àrd.
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
Le bhith a’ cleachdadh theicneòlasan riaghlaidh cumhachd adhartach, faodaidh ESP32-S3 gluasad eadar diofar mhodhan cumhachd. (faic clàr 1).
- Modh gnìomhach: Tha cumhachd aig CPU agus rèidio chip air. Faodaidh a’ chip faighinn, tar-chuir, no èisteachd.
- Modh Modemsleep: Tha an CPU ag obair agus faodar astar a’ ghleoc a lughdachadh. Tha am bann-leathann gun uèir agus an rèidio ciorramach, ach faodaidh ceangal gun uèir fuireach gnìomhach.
- 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. - Modh Deepsleep: Tha an CPU agus a’ mhòr-chuid de na h-iomaill air an cumhachd sìos.
Only the RTC memory is powered on and RTC peripherals are optional. Wi-Fi connection data are stored in the RTC memory. The
Tha coprocessor ULP obrachail.
