TinyUSB partitioned data

[GalatanuM]

Hi!

I am trying to use the STM32 usb functions and I figured out that if the host sends information fragmented in 2 packets of 64 bytes (let's say the first 3 bytes of one complete piece of data that is supposed to be 8 bytes is sent with packet 1 and the other 5 are being sent with packet 2, first 3 bytes are at data_1[61 to 63] and the other 5 bytes are at data_2[0 to 4]. Any idea how I can handle this using report id's and their known size?

This is my bit of code where I read that buffer and that is faulty because I only read the first byte and the other information that is written after that is lost and if everything doesn't line up perfectly when reading again, everything crashes down:

static int8_t CUSTOM_HID_OutEvent_FS(uint8_t event_idx, uint8_t state)
{
  /* USER CODE BEGIN 6 */
	USBD_CUSTOM_HID_HandleTypeDef *hhid = (USBD_CUSTOM_HID_HandleTypeDef *)hUsbDeviceFS.pClassDataCmsit[hUsbDeviceFS.classId];
	g_hhid = hhid;
	switch (event_idx)
	{
	case HID_ID_NEWEFREP:
		new_effect((const FFB_CreateNewEffect_Feature_Data_t*) hhid->Report_buf);
		break;

	case HID_ID_EFFREP:
		set_effect((const FFB_SetEffect_t*) hhid->Report_buf);
		break;

	case HID_ID_CTRLREP:
		ffb_control(hhid->Report_buf[1]); // state = command bitmask
		break;

	case HID_ID_GAINREP:
		set_gain(hhid->Report_buf[1]);
		break;

	case HID_ID_ENVREP: // Envelope
		set_envelope((FFB_SetEnvelope_Data_t *) hhid->Report_buf);
		break;

	case HID_ID_CONDREP:
		set_condition((const FFB_SetCondition_Data_t*) hhid->Report_buf);
		break;

	case HID_ID_PRIDREP: // Periodic
		set_periodic((FFB_SetPeriodic_Data_t*)hhid->Report_buf);
		break;

	case HID_ID_CONSTREP:
		set_constant_effect((const FFB_SetConstantForce_Data_t*) hhid->Report_buf);
		break;

	case HID_ID_RAMPREP: // Ramp
		set_ramp((FFB_SetRamp_Data_t *)hhid->Report_buf);
		break;

	case HID_ID_EFOPREP:
		set_effect_operation((FFB_EffOp_Data_t*)hhid->Report_buf);
		break;

	case HID_ID_BLKFRREP:
		free_effect(state - 1); // state = effect block index
		break;

	default:
		break;
	}

	/* Start next USB packet transfer once data processing is completed */
	if (USBD_CUSTOM_HID_ReceivePacket(&hUsbDeviceFS) != (uint8_t)USBD_OK)
	{
		return -1;
	}

	return (USBD_OK);
  /* USER CODE END 6 */
}

I forgot to ask the main question: How is TinyUSB handling this case?
