При конфигурации GPIO с помощью библиотек, скачанных с сайта STR обнаружил следующее typedef struct { u8 GPIO_Pin; u8 GPIO_Direction; u8 GPIO_Type; u8 GPIO_IPConnected; u16 GPIO_Alternate; }GPIO_InitTypeDef; не понял, что такое IPConnected и для чего эта фича. В DS и UM, скачанных с того же сайта говорится только, что по default`у IPConnected is disable.

Очень странно?!?! При установке J-Tag speed 1000 kHz все получилось.

Использую IAR. Написал программу, залил для отладки во Flash, все шло нормально, смотрел регистры, память и прочее. (PLL не использовался) После исправления обнаруженных неточностей Flash заливаться категорически отказывается.

как, все таки, оживить таймер в симуляторе IAR`а режим рпаботы таймера - PWM настроил Timer01 на тактирование от внутреннено источника (APB), предделитель не используется бит разрешения EN (Coounter enable) установлен спасибо всем откликнувшимся, разобрался

Отлаживаю прогу в симуляторе, но после того как выставляется бит включения таймера он почему-то не инкрементируется.

Настроил прерывания, которые повторяются каждые 1000000 циклов, в окне Interrupt Log показывается, что прерывания симулируются, но при этом в столбце number всегда остаются 0, и не происходит перехода к обработчику прерываний.

спасибо

Возможно ли в иаре имитировать прерывания по внешнему входу, если да, то как?

прочитал, что в одном из слотов векторов прерываний должно храниться какое-то значение, чтобы чексумма векторов с этим значением давала 0, в связи с этим вопрос: это значение как то надо вычислять или оно само определяется??

Как раз ее-то и не хватало. Спасибо. :)

ниче не понимаю, никак не могу войти в прерывание. 1.

Tакой вопрос, если я размещаю код во флэше, значит ли это, что в регистре MEMMAP нужно выставить режим User Flash Mode. Как в IAR объявить isr если прерывание произошло из-за ошибки выборки команды или из-за неверного обращения к памяти, я нашел только __fiq, __irq, __swi. Хотя в кейле существуют extended keywords для подобных случаев.

для чего нужен CSTACK
