哪位大神知道GDde USB HS DMA功能怎么用？我把宏定义改成启用DMA后，原先UVC正常传图形的就不正常了。
这是在 USB_conf.h里面 的宏定义
#ifdef USB_HS_CORE
#define RX_FIFO_HS_SIZE 512
#define TX0_FIFO_HS_SIZE 128
#define TX1_FIFO_HS_SIZE 384
#define TX2_FIFO_HS_SIZE 0
#define TX3_FIFO_HS_SIZE 0
#define TX4_FIFO_HS_SIZE 0
#define TX5_FIFO_HS_SIZE 0
#ifdef USE_ULPI_PHY
#define USB_ULPI_PHY_ENABLED
#endif
#ifdef USE_EMBEDDED_PHY
#define USB_EMBEDDED_PHY_ENABLED
#endif
// #define USB_HS_INTERNAL_DMA_ENABLED
// #define USB_HS_DEDICATED_EP1_ENABLED
#endif /* USB_HS_CORE */ |
