STM32F1 USB
===========
A special **USB** Blue Pill Image that can be used to test if the USB on your board is working. It can also read the MCU internal 'Device Electronic Signature'. Runs in a 64KB Flash STM32F103.

This uses the Mecrisp-Stellaris USB driver for STM32F103 by Jean-Claude Wippler which is based on the Coreforth USB driver by Eckhart Köppen.

.. note:: From Viktor Dvořák. USB needs PC side idVendor = 0x0483 idProduct = 0x7540 driver which is STM32 Virtual COM port driver desribed in en.DM00478229.pdf. The driver is en.stsw-stm32102.zip (24755 kB) is available directly from st.com 

Use it to check for *FAKE STM32F103 MCU's* and let me know if it is useful ?

.. note:: if you don't have a :ref:`Blue Pill<blue-pill>`, read my :ref:`rant<rant-blue-pill>` before thinking about buying one ?

STM32ID
-------
This program is based on the STM32F0 technical documentation because the STM32F1xx technical doc doesn't give the format of the actual "device electronic Unique ID register" and many assume that the format is the same as the STM32F0.

I'm leaning towards the theory that they're slightly different by way of the "lot numbers" because the none of the ASCII data for the F1 chips looks sensible to me so far. Perhaps they are "lot numbers" but just sequential decimal numbers without character based information ?

The "die" and 'wafer number" data seems reasonable in all cases.

However in the F051 signature below, the ASCII lot number layout seems reasonable ? I'll add to this when I get another F051 board set up to read.

-------------------------------------------------
This is the chip/board I developed my 1882bdaff62f637a7bdd517d14f4c1a4.bin image on. It's in a $9 :ref:`Shenzhen LC Technology<lc-mini>` board with 64KB Flash.

.. image:: pics/Shenzhen-LC-mini-STM32F103-board.jpg

I bought 12 of these boards around 2014, one was dead out of the box, no option jumpers etc and one died while being flashed.
