SciFi (28.06.2021 12:57, просмотров: 294) ответил Make_Pic на хотелось понять - подсмотреть как пишется такая софтина - вывод
примитивов, а писать все равно свое под UC1604CЧто-то типа такого:
ส็็็็็็็็็็็็็็็็็็็็็็็็็༼ ຈل͜ຈ༽ส้้้้้้้้้้้้้้้้้้้้้้้
Самолепные форматы шрифтов и растровых изображений с RLE. Самолепные утилитки для их импортирования и преобразования в сишники для вставки в дерево исходников для сборки. Форматы подсмотрены в чужих софтах, на первом этапе целесообразно просто позаимствовать готовые подходящие форматы и утилиты.
