A fost publicat noul episod al proiectului PikaScript 1.8, care dezvolt\u0103 un motor compact pentru scrierea aplica\u021biilor pentru microcontrolere \u00een limbajul Python. PikaScript nu depinde de biblioteci externe \u0219i poate func\u021biona pe microcontrolere cu 4 KB RAM \u0219i 32 KB Flash, cum ar fi STM32G030C8 \u0219i STM32F103C8. Spre compara\u021bie, MicroPython necesit\u0103 16 KB RAM \u0219i 256 KB Flash, iar Snek \u2014 2 KB RAM \u0219i 32 KB Flash. Codul proiectului este scris \u00een limbajul C \u0219i este distribuit sub licen\u021ba MIT. <\/p>\n

PikaScript ofer\u0103 un subset al limbajului Python 3, sus\u021bin\u00e2nd elemente de sintax\u0103 precum operatori de ramificare \u0219i bucle (if, while, for, else, elif, break, continue), operatori de baz\u0103 (+ \u2014 * \/ ), module, \u00eencapsulare, mo\u0219tenire, polimorfism, clase \u0219i metode. Scripturile Python sunt executate pe dispozitive dup\u0103 o precompilare \u2014 PikaScript transform\u0103 mai \u00eent\u00e2i codul Python \u00een cod intern Pika Asm, care este apoi executat pe dispozitivul final. ma\u0219ina virtual\u0103<\/a> Se suport\u0103 rularea direct pe hardware sau \u00een medii RT-Thread, VSF (Versaloon Software Framework) \u0219i Linux.

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

Se remarc\u0103 \u00een mod special simplitatea integr\u0103rii scripturilor PikaScript cu codul scris \u00een limbajul C \u2014 se pot lega func\u021bii scrise \u00een limbajul C la cod, ceea ce permite utilizarea proiectelor mai vechi scrise \u00een C la implementarea PikaScript. Pentru dezvoltarea modulelor C pot fi utilizate medii de dezvoltare existente, cum ar fi Keil, IAR, RT-Thread Studio \u0219i Segger Embedded Studio. Leg\u0103turile sunt generate automat \u00een timpul compil\u0103rii; este suficient s\u0103 defini\u021bi API-ul \u00een fi\u0219ierul cu cod Python, iar leg\u0103tura func\u021biilor C cu modulele Python va fi realizat\u0103 \u00een timpul rul\u0103rii compilatorului Pika Pre-compiler.

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

PikaScript sus\u021bine 24 de microcontrolere, inclusiv diferite modele stm32g*, stm32f*, stm32h*, WCH ch582, ch32*, WinnerMicro w80*, Geehy apm32*, Bouffalo Lab bl-706, Raspberry Pico, ESP32C3 \u0219i Infineon TC264D. Pentru a \u00eencepe rapid dezvoltarea f\u0103r\u0103 echipamente se ofer\u0103 un simulator sau se propune placa de dezvoltare Pika-Pi-Zero bazat\u0103 pe microcontrolerul STM32G030C8T6 cu 64 KB Flash \u0219i 8 KB RAM, care suport\u0103 interfe\u021bele periferice standard (GPIO, TIME, IIC, RGB, KEY, LCD, RGB). De asemenea, dezvoltatorii au preg\u0103tit un generator de proiecte online \u0219i un manager de pachete PikaPackage. <\/p>\n

\u00cen noua versiune a fost implementat\u0103 gestionarea memoriei pe baza num\u0103rului de referin\u021be \u0219i a fost ad\u0103ugat\u0103 suport pentru constructori virtuali (factory method). A fost efectuat\u0103 o diagnosticare a problemelor de memorie folosind instrumentele valgrind. A fost ad\u0103ugat suport pentru compilarea fi\u0219ierelor pc Python \u00een bytecode \u0219i \u00eempachetarea acestora \u00een firmware. A fost implementat\u0103 posibilitatea de a utiliza mai multe fi\u0219iere Python \u00een firmware-uri f\u0103r\u0103 a necesita utilizarea sistemului de fi\u0219iere.
