Objavljen je izdanak projekta PikaScript 1.8, koji razvija kompaktan motor za pisanje aplikacija za mikrokontrolere u programskom jeziku Python. PikaScript nije vezan za vanjske ovisnosti i mo\u017ee raditi na mikrokontrolerima s 4 KB RAM-a i 32 KB Flash-a, kao \u0161to su STM32G030C8 i STM32F103C8. Za usporedbu, za rad MicroPython-a potrebno je 16 KB RAM-a i 256 KB Flash-a, dok Snek zahtijeva 2 KB RAM-a i 32 KB Flash-a. Kod projekta napisan je na jeziku C i distribuira se pod MIT licencom. <\/p>\n

PikaScript pru\u017ea podskup programskog jezika Python 3, koji podr\u017eava sintakti\u010dke elemente kao \u0161to su grananje i petlje (if, while, for, else, elif, break, continue), osnovni operatori (+, -, *, \/, ), moduli, enkapsulacija, naslje\u0111ivanje, polimorfizam, klase i metode. Python skripte se izvr\u0161avaju na ure\u0111ajima nakon prethodne kompajlacije - PikaScript prvo pretvara Python kod u unutarnji bajtkod Pika Asm, koji se na krajnjem ure\u0111aju izvr\u0161ava u posebnoj. virtualnoj ma\u0161ini<\/a> Pika Runtime. Podr\u017eava rad izravno na hardveru ili u okru\u017eenjima RT-Thread, VSF (Versaloon Software Framework) i Linux.

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

Posebno se isti\u010de jednostavnost integracije PikaScript skripti s C kodom - funkcije napisane u jeziku C mogu se povezivati s kodom, \u0161to omogu\u0107uje kori\u0161tenje prethodnih projekte razvijenih u jeziku C prilikom implementacije PikaScript-a. Za razvoj C modula mogu se koristiti postoje\u0107a razvojna okru\u017eenja, kao \u0161to su Keil, IAR, RT-Thread Studio i Segger Embedded Studio. Povezivanja se generiraju automatski u fazi kompajlacije, dovoljno je odrediti API u datoteci s Python kodom, a povezivanje C funkcija s Python modulima bit \u0107e izvr\u0161eno tijekom pokretanja Pika Pre-compiler-a.

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

PikaScript najavljuje podr\u0161ku za 24 mikrokontrolera, uklju\u010duju\u0107i razli\u010dite modele stm32g*, stm32f*, stm32h*, WCH ch582, ch32*, WinnerMicro w80*, Geehy apm32*, Bouffalo Lab bl-706, Raspberry Pico, ESP32C3 i Infineon TC264D. Za brzo zapo\u010dinjanje razvoja bez opreme dostupan je simulator ili se nudi razvojna plo\u010da Pika-Pi-Zero temeljena na mikrokontroleru STM32G030C8T6 s 64 kB Flash-a i 8 kB RAM-a, koja podr\u017eava standardne perifernije su\u010delje (GPIO, TIME, IIC, RGB, KEY, LCD, RGB). Razvija\u010di su tako\u0111er pripremili online generator projekata i paket menad\u017eer PikaPackage. <\/p>\n

U novoj verziji implementirano je upravljanje memorijom na temelju brojanja referenci i dodana je podr\u0161ka za virtualne konstruktore (factory method). Provedena je dijagnostika problema s memorijom kori\u0161tenjem alata valgrind. Dodana je podr\u0161ka za kompilaciju pc-datoteka Python u bajtkod i pakiranje u firmware. Omogu\u0107ena je upotreba vi\u0161e Python-datoteka u firmware bez potrebe za kori\u0161tenjem datote\u010dnog sustava.
