I'm making a keyboard using STM32F103VET6.
Sleep mode was successful using keyboards.
But, It does not wake up.
A problem was found in the code below. (pdev->dev_state == USBD_STATE_SUSPENDED)
uint8_t USBD_HID_SendReport(USBD_HandleTypeDef *pdev, uint8_t *report, uint16_t len)
{
USBD_HID_HandleTypeDef *hhid = (USBD_HID_HandleTypeDef *)pdev->pClassData;
if (pdev->dev_state == USBD_STATE_CONFIGURED)
{
if (hhid->state == HID_IDLE)
{
hhid->state = HID_BUSY;
USBD_LL_Transmit(pdev, HID_EPIN_ADDR, report, len);
}
}
return USBD_OK;
}
How should I approach to solve the problem?
HID Descriptor? or other Method?
