Projekt Raspberry Pi predstavio je novu plo\u010du Raspberry Pi Pico 2, koja nastavlja razvoj mini plo\u010da Pico i Pico W, opremljenih mikrokontrolerom vlastite proizvodnje. Plo\u010da se proizvodi u tvornici Sony i dostupna je po cijeni od 5 dolara. Kao i prethodne Pico plo\u010de, novi model je prvenstveno namijenjen zajedni\u010dkom kori\u0161tenju s ra\u010dunalima Raspberry Pi, razvoju ugra\u0111enih sustava i sustavima za upravljanje raznim ure\u0111ajima. Do kraja godine planira se dodatno izdati model Pico 2 W s podr\u0161kom za Bluetooth i Wi-Fi (2.4GHz 802.11n), implementiran na osnovi \u010dipa Infineon CYW43439. <\/p>\n

Plo\u010da Pico 2 izdvaja se kori\u0161tenjem novog mikrokontrolera RP2350, koji u usporedbi s prethodnim modelima mikrokontrolera RP2040, uklju\u010duje u\u010dinkovitiji dvostruko jezgreni procesor ARM Cortex-M33 s DSP-om i jedinicom za ra\u010dunanje s pomi\u010dnom zarezom, koja radi na frekvenciji od 150MHz (ranije je kori\u0161ten ARM Cortex-M0+ od 133 MHz). Osim toga, ure\u0111aj sadr\u017ei dva opcionalna jezgra Hazard3 s arhitekturom skupa instrukcija RISC-V, na koja se mo\u017ee prebaciti tijekom pokretanja za kori\u0161tenje umjesto jezgra ARM Cortex-M33. <\/p>\n

\u010cip ima 520 KB ugra\u0111ene radne memorije (ranije 264 KB), omogu\u0107uje spajanje vanjskih QSPI PSRAM memorijskih modula i pru\u017ea napredne mogu\u0107nosti sigurnosti. Plo\u010da Pico 2 isporu\u010duje se s 4MB QSPI Flash, \u0161to je dvostruko vi\u0161e nego kod prethodnog modela. Pri tome je plo\u010da u potpunosti kompatibilna s prethodnim modelima na razini hardverskih su\u010delja i softvera koji se koristi za razvoj aplikacija.

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

\u010cip RP2350 uklju\u010duje ugra\u0111ene hardverske mehanizme za za\u0161titu od napada putem umetanja gre\u0161aka (Fault Injection) i podr\u017eava tehnologiju Arm TrustZone, koja se mo\u017ee koristiti za verifikaciju pokretanja putem digitalnog potpisa, pru\u017ea instrukcije za ubrzanje izra\u010duna SHA-256 he\u0161eva i pouzdano generiranje nasumi\u010dnih brojeva (TRNG, True Random Number Generator). Osim toga, dostupno je 8 KB jednokratno programabilne memorije, koja omogu\u0107uje zapisivanje podataka koji se potom ne mogu mijenjati ili brisati. <\/p>\n

Za razvoj aplikacija se lahko uporabljajo jeziki C, C++, MicroPython ali CircuitPython. Razvoj v C\/C++ se lahko izvaja v urejevalniku Visual Studio Code, za katerega je na voljo posebno dopolnilo. Zmo\u017enosti \u010dipa so dovolj za izvajanje aplikacij za re\u0161evanje nalog strojnega u\u010denja, za katere je na voljo prenosni okvir TensorFlow Lite. Za omre\u017eni dostop se priporo\u010da uporaba omre\u017enega sklada lwIP, ki je vklju\u010den v Pico SDK za razvoj aplikacij v jeziku C, pa tudi v programsko opremo za MicroPython.
