Appendix - source code examples

6.1

Project code example

A firmware package is linked with this document. It contains source codes in C-language

which give examples of some of the precision improvement methods described in this

application note. This complete project is designed for the ST Visual Develop (STVD)

development environment and Cosmic compiler and using the STM8 evaluation board. With

these examples you can see how the method is implemented in practice and you can test it

by comparing ADC precision with the improvement method and without it.

Package name: STM8_ADC_improvement.zip

Project name: STM8_ADC_improvement.stw
