21-Mar-2012

Inserted missing text on page 9.

10-Aug-2012

Replaced "STM32F20x, STM32F21x, STM32F40x and STM32F41x

microcontrollers" by: "STM32F20x / STM32F21x (revZ, revY, revX)

and STM32F40x/STM32F41x (revZ) microcontrollers" in the

Introduction.

Added Appendix A: Averaging of N ADC samples: source code and

Appendix B: Averaging of N-X ADC samples: source code, and

corresponding notes in Section 2.1.1 and Section 2.1.2.

25-Feb-2013

Applied to STM32F2xx (STM32F20x, STM32F21x) and STM32F4xx

(STM32F40x, STM32F41x, STM32F42x, STM32F43x)

microcontrollers.

Section 3 now dedicated to STM32F2xx, STM32F405, STM32F415,

STM32F407 and STM32F417 products, when new Section 4 is

dedicated to STM32F42x/F43x products.

Added Appendix C: Firmware sequence to activate Option 1 and

Option 2.
