Verdris,

This is a good idea, thanks for sharing.

Of course there are more other viable solutions (I can extend your idea) and talk about my current solution (64 channels, 16 bits ADC, single ended, etc) which are more powerful than STM32. What I'm following is to see how much of its power I can squeeze of it with keeping the combination between efficiency, ease of programming and reduced costs because the project I'm working on it (gas chromatography) must be implemented in many equipments.

Thanks.

Noom:

It would be a bad solution to mutliplex or use external shield while STM32 core has already powerful capabilities.

mhzpower:

I'm afraid I'm not sure what your first phrase means, my english is not that good. If I correctly understood your question, yes, my inputs needs as much Samples/sec as it is possible. Currently we use 1kS/sec per channel but with other devices.

Chris Walker:

The STM32 core is capable to use more than those 6 analog pins. So I'm heading toward some tweaking, though I'm still confused about how this can be done. For example I start to look what IDE and C libraries STM offers.

If you have any clues or ideas which you can share with us about tweaking firmware, please let us know.

It would be great to combine ethernet with 8 analog inputs

Yes, there are and all of them works but I need more than 6 analog inputs. This is why I want (and try) to use GPIO pins.

Hi Chris,

The link for STDFU Tester doesn't work anymore and i can't find the application on www.st.com

Can you help us, please ?

Many thanks!
