Proiectul Raspberry Pi a lansat noua plac\u0103 Raspberry Pi Pico 2, continu\u00e2nd dezvoltarea pl\u0103cilor miniaturale Pico \u0219i Pico W, echipate cu un microcontroler dezvoltat intern. Placa este fabricat\u0103 de Sony \u0219i este disponibil\u0103 la pre\u021bul de 5 dolari. Ca \u0219i pl\u0103cile Pico anterioare, noul model este destinat \u00een principal colabor\u0103rii cu computerele Raspberry Pi, dezvolt\u0103rii sistemelor \u00eencorporate \u0219i controlului diverselor dispozitive. P\u00e2n\u0103 la sf\u00e2r\u0219itul anului, se preconizeaz\u0103 lansarea suplimentar\u0103 a modelului Pico 2 W cu suport pentru Bluetooth \u0219i Wi-Fi (2.4GHz 802.11n), implementat pe baza cipului Infineon CYW43439. <\/p>\n

Placa Pico 2 se remarc\u0103 prin utilizarea noului microcontroler RP2350, care, spre deosebire de microcontrolerul RP2040 folosit \u00een modelele anterioare, include un procesor dual-core ARM Cortex-M33 mai performant, cu DSP \u0219i un modul pentru calcule cu virgul\u0103 mobil\u0103, care func\u021bioneaz\u0103 la o frecven\u021b\u0103 de 150MHz (anterior a fost utilizat ARM Cortex-M0+ la 133 MHz). \u00cen plus, sunt incluse dou\u0103 nuclee op\u021bionale Hazard3 cu arhitectura setului de instruc\u021biuni RISC-V, care pot fi activate \u00een timpul boot-ului pentru a fi folosite \u00een locul nucleelor ARM Cortex-M33. <\/p>\n

Chipul este echipat cu 520 KB de memorie RAM integrat\u0103 (anterior erau 264 KB), permite conectarea modulelor externe de memorie QSPI PSRAM \u0219i ofer\u0103 capacit\u0103\u021bi extinse pentru asigurarea securit\u0103\u021bii. Placa Pico 2 vine cu 4MB QSPI Flash, ceea ce reprezint\u0103 dublu fa\u021b\u0103 de modelul anterior. De asemenea, placa este complet compatibil\u0103 cu modelele anterioare la nivel de interfe\u021be hardware \u0219i software utilizate pentru dezvoltarea aplica\u021biilor.

\"A<\/center> <\/p>\n

Chipul RP2350 con\u021bine resurse hardware integrate pentru protec\u021bia \u00eempotriva atacurilor de tip Fault Injection \u0219i suport\u0103 tehnologia Arm TrustZone, care poate fi utilizat\u0103 pentru verificarea boot-ului prin semn\u0103tur\u0103 digital\u0103, ofer\u0103 instruc\u021biuni pentru accelerarea calculului hash-urilor SHA-256 \u0219i generarea sigur\u0103 de numere aleatoare (TRNG, True Random Number Generator). \u00cen plus, este disponibil\u0103 o memorie programabil\u0103 o singur\u0103 dat\u0103 de 8 KB, care permite scrierea datelor ce nu pot fi modificate sau \u0219terse ulterior. <\/p>\n

Pentru crearea aplica\u021biilor pot fi folosite limbaje precum C, C++, MicroPython sau CircuitPython. Dezvoltarea \u00een C\/C++ poate fi realizat\u0103 \u00een editorul Visual Studio Code, pentru care exist\u0103 un plugin special. Capacit\u0103\u021bile cipului sunt suficiente pentru realizarea aplica\u021biilor destinate solu\u021bion\u0103rii problemelor de \u00eenv\u0103\u021bare automat\u0103, pentru dezvoltarea c\u0103rora este disponibil un port al framework-ului TensorFlow Lite. Pentru accesul la re\u021bea, se recomand\u0103 utilizarea stivei de re\u021bea lwIP, care este inclus\u0103 \u00een Pico SDK pentru dezvoltarea aplica\u021biilor \u00een limbajul C, precum \u0219i \u00een firmware-ul cu MicroPython.
