Raspberry Pi-projektet har introducerat ett nytt kort, Raspberry Pi Pico 2, som bygger vidare p\u00e5 de kompakta Pico- och Pico W-korten, som \u00e4r utrustade med en egenutvecklad mikrokontroller. Kortet tillverkas av Sony och kostar 5 dollar. Precis som de tidigare Pico-korten \u00e4r den nya modellen fr\u00e4mst inriktad p\u00e5 att anv\u00e4ndas tillsammans med Raspberry Pi-datorer, utveckling av inbyggda system och kontroll av olika enheter. En Pico 2 W-modell med st\u00f6d f\u00f6r Bluetooth och Wi-Fi (2.4GHz 802.11n), baserad p\u00e5 Infineon CYW43439-chippen, planeras att sl\u00e4ppas innan \u00e5rets slut. <\/p>\n

Pico 2-kortet utm\u00e4rker sig med den nya mikrokontrolleren RP2350, som j\u00e4mf\u00f6rt med den som anv\u00e4ndes i de tidigare modellerna, RP2040, har en mer kapabel dual-core ARM Cortex-M33-processor med DSP och en flyttalsenhet som arbetar p\u00e5 en frekvens av 150 MHz (tidigare anv\u00e4ndes ARM Cortex-M0+ 133 MHz). Dessutom inkluderar det tv\u00e5 valfria Hazard3-k\u00e4rnor med RISC-V-kommandosats-arkitektur, som kan v\u00e4xlas vid uppstart f\u00f6r att anv\u00e4ndas ist\u00e4llet f\u00f6r ARM Cortex-M33-k\u00e4rnorna. <\/p>\n

Chippet har 520 KB inbyggd RAM (tidigare 264 KB), g\u00f6r det m\u00f6jligt att ansluta externa QSPI PSRAM-moduler och erbjuder f\u00f6rb\u00e4ttrade s\u00e4kerhetsfunktioner. Pico 2-kortet levereras med 4 MB QSPI Flash, vilket \u00e4r dubbelt s\u00e5 mycket som i f\u00f6reg\u00e5ende modell. Kortet \u00e4r helt kompatibelt med tidigare modeller n\u00e4r det g\u00e4ller h\u00e5rdvaru- och programvarugr\u00e4nssnitt som anv\u00e4nds f\u00f6r applikationsutveckling.

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

RP2350-chippet har inbyggda h\u00e5rdvaruskydd mot felinjektion (Fault Injection) och st\u00f6der Arm TrustZone-teknologin, som kan anv\u00e4ndas f\u00f6r att verifiera uppstart genom digital signatur, erbjuder instruktioner f\u00f6r att p\u00e5skynda SHA-256-hashber\u00e4kningar samt p\u00e5litlig generation av slumpm\u00e4ssiga tal (TRNG, True Random Number Generator). Dessutom erbjuds 8 KB eng\u00e5ngs-programmerbart minne, vilket ger m\u00f6jlighet att skriva data som sedan inte kan \u00e4ndras eller raderas. <\/p>\n

F\u00f6r att skapa applikationer kan spr\u00e5k som C, C++, MicroPython eller CircuitPython anv\u00e4ndas. Utveckling p\u00e5 C\/C++ kan ske i redigeraren Visual Studio Code, f\u00f6r vilken det finns ett speciellt till\u00e4gg. Chipet har tillr\u00e4ckliga resurser f\u00f6r att k\u00f6ra applikationer f\u00f6r maskininl\u00e4rningsuppgifter, f\u00f6r vilka det finns en port av ramverket TensorFlow Lite. F\u00f6r n\u00e4tverks\u00e5tkomst rekommenderas att anv\u00e4nda n\u00e4tverksstacken lwIP, som ing\u00e5r i Pico SDK f\u00f6r utveckling av applikationer p\u00e5 C, liksom i den fasta programvaran med MicroPython.
