ГОСПОДА!!! И правда мистика.....Вот - только что взял свой код и адаптировал его под CodeVision - только лишь синтаксически изменил способ включения/выключения портов. Ну и небольшое отличие в синтаксисе инициализации АЦП.
ВСЕ РАБОТАЕТ!!!!
Типерь внимание:
Я убрал задержки отовсюду, посадил это дело на оптику. Частота чипа - 16 МГц, частота АЦП 125 кГц. Запустил цикл, а в главнои цикле добавил включение диода 5 порта D, если будет хотябы одна ошибка.
Колоссальное количество таких операций в секунду. И вот 5 минут у меня девайс работает - ни одной ошибки.
ПРостите мне мою глупую просьбу, но посмотрите предыдущий код и этот, для CodeVision - одинаково ли настроены АЦП? просто я уже устал...

И честное слово обидно ... что третий день бьюсь и бестолку.
Обидно за себя, потому как все эти три дня считал себя недостойным даже звания любителя.
А тут бах - и за полчаса сделал...
Господа, наверное и у вас есть такое чувство - когда вы над чем-то бьетесь, сколько бы времени это не отнимало - вы всегда чувствуете "вектор" направленный в сторону проблемы и есть ощущение того, что еерешение - это вопрос времени.
Но вот когда этого "вектора" нет - проблема действительно оказывается мистической..
Вот еще makefile - гляньте, может здесь собака зарыта...

Помогите найти ошибку в программе. Или глюк АЦП?
