Проектиране на приложения с LPC2364

2

Да се осигури работата на LPC2364 като се проектира:

Външен кристален осциалтор за main oscilator и RTC oscilator;

Етелонно напрежение за ADC;

Осигуряване на reset сигнал;

Регулирано захранващо напрежение;

Следене на захранването;

Събуждане на процесора от power-down режим;

Вход за прихващане на данни;

Аналогв вход за ADC;

Вътрешен интерфейс I2C;

Междусистемен интерфейс RS485;

ETHERNET;

Както и инициализации на използвания хардуер;
