stm32f103 USB hid library is not very useful Im on that new CubeIDE, all updated. My MCU is f103.Making hid device, which should have a few reports, more than 1. So, i edited report descriptor, added reportID, added second report. Windows recognizes it just fine.But what a surprise, second report getting to the host ok, while first one - not so much. Why.No need to search too much.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 nice is that. Lets try to figure out what is going on. (skipping that bizarre happy code, always returning "ok", i saw that reported on that forum multiple times, but why would ST care... )First time u call it, function will pass pointer to data, it will get copied into PMA.But if u c
