Ресет модуля, Exception 0: Illegal instruction

Ma_Bo · 9 Мар 2023

Доброго!
делаю управление замком. Использую сканер отпечатка пальцев FPM10A и NodeMCU c Асинхронным ВебСервером.
Т.е. дергается пин либо с веб-странички, либо со сканера.
Код состоит из двух. Первая часть- это код Rui Santos https://RandomNerdTutorials.com/esp32-esp8266-web-server-physical-button/
Вторая часть -это код из примера библиотеки <Adafruit_Fingerprint.h>
Все компилируется, загружается, начинает работать как надо- и оп-па через 7-8 секунд ребут с вот такой ошибкой

Exception 0: Illegal instruction
PC: 0x4020c71c
EXCVADDR: 0x00000000
............................................

Если по частям, то и веб-сервер и сканер отпечатков работают отлично! Собственно ХЕЛП!!!!
