forked from Elron_dev/elbear_arduino_bsp
v0.5.0
- добавлена поддержка платы ELBEAR ACE-NANO; - добавлена поддержка плат ELSOMIK OEM и SE; - добавлена возможность работы в режиме отладки для всех плат, входящих в состав пакета. Доступно для версии ArduinoIDE 2 и выше; - добавлена поддержка библиотеки FreeRTOS; - добавлена поддержка библиотеки IRremote; - добавлена поддержка библиотеки OneWire; - добавлена поддержка аппаратного I2C0 для плат START-MIK32 и ELSOMIK. Для работы с ним доступен экземпляр класса Wire1; - добавлена поддержка аппаратного SPI0 для всех плат, входящих в пакет. Для работы с ним доступен экземпляр класса SPI1; - увеличено быстродействие функций digitalWrite, digitalRead; - исправлены известные ошибки.
