Обновление до версии 0.3.0
- обновлен elbear_fw_bootloader - добавлена проверка контрольной суммы каждой строки hex файла. - в модуль работы с АЦП добавлена функция analogReadResolution(). Функция analogRead() теперь возвращает усредненное по 10 измерениям значение. - общая функция обработки прерываний перенесена в память RAM. Обработчики прерываний модулей External Interrupts и Advanced I/O (функция tone()) так же перенесены в память RAM для увеличения скорости выполнения кода. - в пакет добавлены библиотеки EEPROM, Servo, SoftSerial, NeoPixel, MFRC522 адаптированные для работы с платой Elbear Ace-Uno. - добавлено описание особенностей работы с пакетом
