- 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

EEPROM Update method
|

|
|
Stores values read from analog input 0 into the EEPROM.
|
|
These values will stay in the EEPROM when the board is
|
|
turned off and may be retrieved later by another sketch.
|
|
|
|
If a value has not changed in the EEPROM, it is not overwritten
|
|
which would reduce the life span of the EEPROM unnecessarily.
