Hi,

I have read this app. note:

http://www.st.com/web/en/resource/technical/document/application_note/CD00293110.pdf

I would like to get more informations, source code, etc. In app note there says:

''

it is possible to increase the number of effective bits from 10 bits (see

Section 1.6: Thermal noise present on STM32 meter platform

) up to the 14 bits necessary to reach the required precision of the whole system. The theory and implementation of the resolution enhancement by oversampling is described in a separate document supplied on request.''

Why is the source code and ather documents related to this app. note kept secret? Where can we get the full text of this app. note?

Hi bursic.marko,

Generally ''on request'' means that you have to contact your local distributor or FAE get the resource.

Some tips on how to improve ADC accuracy on STM32F2 and STM32F4 products are already provided in

http://www2.st.com/content/ccc/resource/technical/document/application_note/a0/71/3e/e4/8f/b6/40/e6/DM00050879.pdf/files/DM00050879.pdf/jcr:content/translations/en.DM00050879.pdf
