+/**********************************************
+ * This driver has been tested with the following MCUs:
+ *
+ *
+ * STM32F070RB
+ *
+ *
+ * It also should work with minimal changes for any ST MCU with an "USB A"/"PCD"/"HCD" peripheral. This
+ * covers:
+ *
+ * F04x, F072, F078, 070x6/B 1024 byte buffer
+ * F102, F103 512 byte buffer; no internal D+ pull-up (maybe many more changes?)
+ * F302xB/C, F303xB/C, F373 512 byte buffer; no internal D+ pull-up
+ * F302x6/8, F302xD/E2, F303xD/E 1024 byte buffer; no internal D+ pull-up
+ * L0x2, L0x3 1024 byte buffer
+ * L1 512 byte buffer
+ * L4x2, L4x3 1024 byte buffer
+ *
+ * Assumptions of the driver:
+ * - dcd_fs_irqHandler() is called by the USB interrupt handler
+ * - USB clock enabled before usb_init() is called; Perhaps use __HAL_RCC_USB_CLK_ENABLE();
+ * - You are not using CAN (it must share the packet buffer)
+ * - APB clock is >= 10 MHz
+ * - On some boards, series resistors are required, but not on others.
+ * - On some boards, D+ pull up resistor (1.5kohm) is required, but not on others.
+ * - You don't have long-running interrupts; some USB packets must be quickly responded to.
+ * - You have the ST CMSIS library linked into the project. HAL is not used.
+ *
+ * Current driver limitations (i.e., a list of features for you to add):
+ * - STALL handled, but not tested.
+ * - Does it work? No clue.
+ * - Only tested on F070RB; other models will have an #error during compilation
+ * - All EP BTABLE buffers are created as max 64 bytes.
+ * - Smaller can be requested, but it has to be an even number.
+ * - No isochronous endpoints
+ * - Endpoint index is the ID of the endpoint
+ * - This means that priority is given to endpoints with lower ID numbers
+ * - Code is mixing up EP IX with EP ID. Everywhere.
+ * - No way to close endpoints; Can a device be reconfigured without a reset?
+ * - Packet buffer memory is copied in the interrupt.
+ * - This is better for performance, but means interrupts are disabled for longer
+ * - DMA may be the best choice, but it could also be pushed to the USBD task.
+ * - No double-buffering
+ * - No DMA
+ * - No provision to control the D+ pull-up using GPIO on devices without an internal pull-up.
+ * - Minimal error handling
+ * - Perhaps error interrupts sholud be reported to the stack, or cause a device reset?
+ * - Assumes a single USB peripheral; I think that no hardware has multiple so this is fine.
+ * - Add a callback for enabling/disabling the D+ PU on devices without an internal PU.
+ * - F3 models use three separate interrupts. I think we could only use the LP interrupt for
+ * everything? However, the interrupts are configurable so the DisableInt and EnableInt
+ * below functions could be adjusting the wrong interrupts (if they had been reconfigured)
+ * - LPM is not used correctly, or at all?
+ *
+ * USB documentation and Reference implementations
+ * - STM32 Reference manuals
+ * - STM32 USB Hardware Guidelines AN4879
+ *
+ * - STM32 HAL (much of this driver is based on this)
+ * - libopencm3/lib/stm32/common/st_usbfs_core.c
+ * - Keil USB Device http://www.keil.com/pack/doc/mw/USB/html/group__usbd.html
+ *
+ * - YouTube OpenTechLab 011; https://www.youtube.com/watch?v=4FOkJLp_PUw
+ *
+ * Advantages over HAL driver:
+ * - Tiny (saves RAM, assumes a single USB peripheral)
+ *
+ * Notes:
+ * - The buffer table is allocated as endpoints are opened. The allocation is only
+ * cleared when the device is reset. This may be bad if the USB device needs
+ * to be reconfigured.
