PikaScript 1.8-utslett er publisert, og utvikler en kompakt motor for \u00e5 skrive applikasjoner for mikrokontrollere med Python. PikaScript er ikke avhengig av eksterne avhengigheter og kan kj\u00f8re p\u00e5 mikrokontrollere med 4 KB RAM og 32 KB Flash, for eksempel STM32G030C8 og STM32F103C8. For sammenligning krever MicroPython 16 KB RAM og 256 KB Flash, mens Snek \u2014 2 KB RAM og 32 KB Flash. Prosjektkoden er skrevet i C og distribueres under MIT-lisensen. <\/p>\n

PikaScript tilbyr et delsett av Python 3, som st\u00f8tter syntakselementer som betingede og iterative operat\u00f8rer (if, while, for, else, elif, break, continue), grunnleggende operatorer (+ \u2014 * \/ ), moduler, inkapsling, arv, polymorfisme, klasser og metoder. Python-skript kj\u00f8res p\u00e5 enheter etter forh\u00e5ndskompilering \u2014 PikaScript konverterer f\u00f8rst Python-koden til intern bytekode i Pika Asm, som deretter kj\u00f8res p\u00e5 enheten. en virtuell maskin<\/a> Pika Runtime. Drift st\u00f8ttes direkte p\u00e5 maskinvaren eller i milj\u00f8ene RT-Thread, VSF (Versaloon Software Framework) og Linux.

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

Det skal spesielt nevnes hvor enkelt det er \u00e5 integrere PikaScript-skript med C-kode \u2014 C-funksjoner kan kobles til koden, noe som gj\u00f8r det mulig \u00e5 bruke eksisterende arbeid fra eldre C-prosjekter ved implementering av PikaScript. Utviklingsmilj\u00f8er som Keil, IAR, RT-Thread Studio og Segger Embedded Studio kan brukes til utvikling av C-moduler. Kobbinger genereres automatisk under kompileringen, det er tilstrekkelig \u00e5 definere API-et i Python-koden, s\u00e5 vil koblingen av C-funksjoner til Python-moduler bli utf\u00f8rt under oppstart av Pika Pre-compiler.

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

PikaScript oppgir st\u00f8tte for 24 mikrokontrollere, inkludert forskjellige modeller stm32g*, stm32f*, stm32h*, WCH ch582, ch32*, WinnerMicro w80*, Geehy apm32*, Bouffalo Lab bl-706, Raspberry Pico, ESP32C3 og Infineon TC264D. For en rask start p\u00e5 utvikling uten maskinvare tilbys en simulator eller et utviklerkort, Pika-Pi-Zero, basert p\u00e5 mikrokontrolleren STM32G030C8T6 med 64 KB Flash og 8 KB RAM, som st\u00f8tter typiske perifere grensesnitt (GPIO, TIME, IIC, RGB, KEY, LCD, RGB). Utviklerne har ogs\u00e5 forberedt en online prosjektgenerator og pakkeadministrator PikaPackage. <\/p>\n

I den nye versjonen er det implementert minneh\u00e5ndtering basert p\u00e5 referansetelling og lagt til st\u00f8tte for virtuelle konstrukt\u00f8rer (fabrikkmetode). Det er utf\u00f8rt diagnostikk av minneproblemer ved hjelp av Valgrind-verkt\u00f8yet. St\u00f8tte for kompilering av Python pc-filer til bytekode og pakking i fastvare er lagt til. Muligheten for \u00e5 bruke flere Python-filer i fastvare uten behov for filsystem er realisert.
