но как не бьюсь не мог увывести свой символ, например квадрат, 20х20 пикселей....

да, с этим разобрался, как вывести свой символ,хоть какого размера, вот результаты эксперимента, пока правда, на LCD 3310, так как он был у меня в Протеусе

при нажатии на кнопку появляется символ...
сейчас буду пробовать это перенести на SSD1306

ещё вопрос интересный: хочу для примера сделатьтак,чтобы после включения отображался некий символ, который должен быть постоянно высвечен, а при нажатии кнопки появлялся ещё один символ, в другом месте, изменил свой предыдущий код вот так:

то, что должно постоянно отображаться-это
PosX=45:PosY=1:GOSUB LCD_GotoXY
HIGH DC
SHIFTOUT DTA,CLK,1,[$3c,$3c,$3c,$3c]
(маленький квадрат)
но он почему-то не светится постоянно, я мигает...а при нажатии на кнопку на RA1 светится постоянно...пока кнопку не отпустишь, пробовыл выводить этот кусок отдельной подпрограммой-эффект тот же...помогите, пожалуйста, разобраться, какой же алгоритм должен быть для этого, я уверен, что это именно в алгоритме дело.
