Нужна помощь Мигание светодиодом по команде UART

Meinframe · 14 Июл 2015

Подскажите. Я пытаюсь соединить пример работы по UART (http://41j.com/blog/2015/01/esp8266-serial-uart0-txrx/) и пример мигания светодиодом "Blinky" из esp_iot_sdk_v0.9.5_15_01_23.zip (https://github.com/esp8266/esp8266-wiki/tree/master/sdk).

Проблема в изменении, как мне кажется, флага по UART. Так как я проверял, что задача мигания выполняется и не выполняется при начальном значении флага 1 или 0 соответственно. Вопрос что я делаю не так? куда копать?
