Posted on December 24, 2014 at 09:32im trying use usb host and device same time
but the host totally not functional
i tried to use USB HS port as FS host only DM and DP pin used
use internel PHY , 5V power source checked
the interrupt have no response
there are some init codes here
void USBHost_Init()
{
USBH_Init(&USB_OTG_Host,
USB_OTG_FS_CORE_ID,
&USB_Host,
&USBH_MSC_cb,
&USR_Callbacks);
}
void USB_OTG_BSP_Init(USB_OTG_CORE_HANDLE *pdev)
{
GPIO_InitTypeDef GPIO_InitStructure;
RCC_AHB1PeriphClockCmd( RCC_AHB1Periph_GPIOB , ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_15 |
GPIO_Pin_14;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;
GPIO_Init(GPIOB, &GPIO_InitStructure);
GPIO_PinAFConfig(GPIOB,GPIO_PinSource15,GPIO_AF_OTG2_FS) ;
GPIO_PinAFConfig(GPIOB,GPIO_PinSource14,GPIO_AF_OTG2_FS) ;
RCC_AHB1PeriphClockCmd( RCC_AHB1Periph_OTG_HS, ENABLE) ;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_OTG_FS, ENABLE) ;
}
void USB_OTG_BSP_EnableInterrupt(USB_OTG_CORE_HANDLE *pdev)
{
NVIC_InitTypeDef NVIC_InitStructure;
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_1);
NVIC_InitStructure.NVIC_IRQChannel = OTG_HS_IRQn;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 3;
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);
}
im very appreciate if someone can help
