STM32F103 + EXTI + время

Помогите разобраться пожалуйста.
Имеется плата HY-MINI32. Не получается реализовать все кнопки, которых 11 штук. И не понял почему не работают глобальные переменные. Например, в задаче с LED инкрементируется счетчик time1, который в другой задаче выводится на LCD, но значение не меняется; тоже и с остальными. Нажатие любой кнопки меняет состояние светодиода LED1(PB0). Однако он иногда мигает как-будто по UART обмен отражаю его миганием и не все кнопки меняют его состояние (Проблемы с PD3, PC10).
Код ниже... Кнопки на PD0-PD6, PC10-PC13

Если переменная изменяется в прерывании, то она должна быть объявлена как volatile

0

Хаотичное срабатывание прерываний решилось привязкой входов к земле. Правда только 7 линий прерываний удалось использовать. Остальные не реагируют. Изменение переменных происходит по прерыванию, volatile не помогает. Если успеваю изменить переменную до первой прорисовки экрана - то рисуется с измененным значением переменной. Спасибо за помощь.
