Raspberry Pi-projektet har pr\u00e6senteret det nye Raspberry Pi Pico 2-kort, som forts\u00e6tter udviklingen af de miniature Pico- og Pico W-kort, der er udstyret med en mikrocontroller af egen udvikling. Kortet fremstilles p\u00e5 Sony's fabrik og er tilg\u00e6ngeligt til en pris p\u00e5 5 dollars. Ligesom de tidligere Pico-kort er den nye model prim\u00e6rt rettet mod samarbejde med Raspberry Pi-computere, udvikling af indlejrede systemer og styring af forskellige enheder. Inden \u00e5rets slutning planl\u00e6gges det at udgive en yderligere model, Pico 2 W, med support for Bluetooth og Wi-Fi (2.4GHz 802.11n), implementeret p\u00e5 basis af Infineon CYW43439-chippen. <\/p>\n

Pico 2-kortet er bem\u00e6rkelsesv\u00e6rdigt ved at benytte den nye RP2350-mikrocontroller, som i forhold til den mikrocontroller, der blev brugt i tidligere modeller, RP2040, inkluderer en mere kraftfuld dual-core ARM Cortex-M33-processor med DSP og flydende punkt-funktioner, der k\u00f8rer ved 150MHz (tidligere blev ARM Cortex-M0+ 133 MHz brugt). Derudover inkluderer det to valgfri Hazard3-kjerner med RISC-V-kommandos\u00e6tarkitektur, som kan skiftes til under opstart for at bruges i stedet for ARM Cortex-M33-kernene. <\/p>\n

Chips\u00e6ttet har 520 KB indbygget RAM (tidligere var det 264 KB), muligg\u00f8r tilslutning af eksterne QSPI PSRAM-moduler og tilbyder udvidede sikkerhedsfunktioner. Pico 2-kortet leveres med 4MB QSPI Flash, hvilket er dobbelt s\u00e5 meget som i den tidligere model. Desuden er kortet fuldt kompatibelt med tidligere modeller hvad ang\u00e5r hardwaregr\u00e6nseflader og software, der anvendes til udvikling af applikationer.

RP2350-chippen indeholder indbyggede hardwarefunktioner til beskyttelse mod fejlinds\u00e6ttelsesangreb (Fault Injection) og underst\u00f8tter Arm TrustZone-teknologien, som kan bruges til digital signaturverifikation under opstart, giver instruktioner til accelerationen af SHA-256 hash-beregninger og p\u00e5lidelig tilf\u00e6ldig talgenerering (TRNG, True Random Number Generator). Desuden tilbydes 8 KB engang-programmerbar hukommelse, som g\u00f8r det muligt at skrive data, der derefter ikke kan \u00e6ndres eller slettes. <\/p>\n

Forskellige programmeringssprog som C, C++, MicroPython eller CircuitPython kan bruges til at udvikle applikationer. Udvikling med C\/C++ kan udf\u00f8res i Visual Studio Code, som har et specialtilpasset plugin. Chippen har tilstr\u00e6kkelige ressourcer til at h\u00e5ndtere applikationer til maskinl\u00e6ring, for hvilke der findes en port af TensorFlow Lite-rammev\u00e6rket. For netv\u00e6rksadgang anbefales det at bruge netv\u00e6rksstakken lwIP, som er inkluderet i Pico SDK til udvikling af applikationer i C, s\u00e5vel som i firmware med MicroPython.
