John, yes I have an STM3210E-EVAL board at hand and I have developed the driver
against that board. I tried to communicate with the temperature sensor, but due
to a limitation of the microcontroller, it is not possible to use the I2C1 bus
when the FSMC is activated (see Errata Sheet of the STM32F101xC/D/E in section
2.6.9).
So, to test, I modified the Eval Board and connected an external I2C device.
