External control of block parameters

 

 Hi,

               I am working in an audio system that needs a STM32F407 to run stand alone. How can I modify block parameters via potentiometers or a touch screen?

               I can change parameters via GPIO, but it would be great to change analog parameters.

       

        Thanks!

Hey AleFourcade,

 

Sorry about the (very) late response. 

The new 's1.4' ST BSPs that are now posted on our downloads page have an example GPIO_SourceSink.awd layout that shows an example that uses input from the blue user button on the STM32F407 Disco board. Using this layout and by looking at the included reference source code (start with ControlDriver.c), you should be able to set up your board to use analog inputs.

 

I hope this helps

-Axel

I have a similar need.  Can you provide links to the relevant documentation and source code?  Thanks.

Hi,

 

You can get the s1.4 version of the STM32F407 here: https://dspconcepts.com/downloads
