Howdy Serge,
Sorry for the late reply. I think I may have overlooked this post when accessing my email.
- In the post above, you mention that the temperature data looks reasonable in auto mode. Is this the code displayed above?
- When using direct mode, are you internally or externally triggering the conversions?
- What are the values of the AMC Status/Configuration and ADC Control registers when in direct mode?
One quick way to verify that you are properly converting channels in direct mode is to read the DAVF bit. In direct-mode, after the ADC Data registers update, the DAVF bit in the AMC Status/Config Resister is set to '1'.
