Здравствуйте! help.gif
Помогите пожалуйста!
Проблемма:
Имеется CY7C68013A. Написаны дескрипторы и т.д. система определяет USB audio device, как и требовалось, а конкретнее USB Speaker. Драйвер стандартный используется. Тип передачи изохронный. Так вот пытаюсь в него передать данные например Winamp-ом и смотру как данные идут в настройке драйвера выхода (DirectSound вкладка статус в винампе), а он пишет что отправил 1280байт (примерно) и стоит. В чем может быть проблемма? В программе для контроллера в функции TD Pool в регистры пишется EP2BCH=0, а EP2BCL=0x80.
Чать кода привожу..


void TD_Poll(void) // Called repeatedly while the device is idle
{
// Audio control action
if( !(EP2CS & bmEPEMPTY) ) //EP2CS & bmEPFULL ) // Is there something available
{

IOB = EP2FIFOBUF[0];

EP2BCH = 0;
EP2BCL = 0x80; // Rearm endpoint buffer
}
}

Может кто делал такое и кусочком исходника поделится?
Помогите!!! Уже неделю бьюсь.

Ну, можно написать так:
Код
void TD_Poll(void) // Called repeatedly while the device is idle
{
   // Audio control action
   while(!(EP2468STAT & bmEP2EMPTY))
   {
      IOB = EP2FIFOBUF[0];

      SYNCDELAY;
      EP2BCL = 0x80; // Rearm endpoint buffer
      SYNCDELAY;
   }
}

И все же, более простой путь - вначале отладить обмен firmware с драйвером "SuiteUSB.NET 2.0". А уже затем использовать стандартный драйвер Windows и аудио приложение.

Аналогичная проблема как и у автора. Решение не было найдено?

У ТС не написано ничего, так что понять причину нельзя. Возможно, забыли про синхронизацию. В USB Audio на вывод нужно обязательно завести еще один endpoint для синхронизации и подтверждать скорость приема данных.

В юсб аудио 1.0 есть синхронный, адаптивный и асинхронный режимы синхронизации. Асинхронный делится на имплисит и експлисит и только последний требует для своей работы явный канал синхронизации. Но работает и без него, по крайней мере со стандартным драйвером вин хп и 7, при этом слышны щелчки с частотой равной разнице частот хоста и конечной точки.

Без разницы какой режим синхронизации использую, результат один и тот же. При попытке воспроизвести звук наблюдается примерно следующее:

Проект прикрепил к сообщению. За основу был взят сайпросовский пример, поэтому и название проекта такое.

Проблема решилась очень просто - так как используется HighSpeed, то вместо bInterval для конечной точки необходимо было указать = 4 (125мкс * 2^(bInterval-1) = 1мс).

В итоге всё завелось, добавил фитбек для синхронизации и столкнулся с проблемой: после каждой передачи по фитбеку хост даёт Sync reset pipe and clear stall.
может кто-нибудь сталкивался или есть мысли из за чего такое может быть?
