Recommendations on recreating STM32CubeMX .ioc file from ST Example code

[JFlowers]

Hello Everyone,

 

Since the STM32CubeMX .ioc file does not exist for the DAC_GenerateWaveform_TriggerHW example code (as usual), does anyone have suggestions/recommendations on the best way to recreate it?

 

Seems like I need to make iterative guesses in STM32CubeMX and then see if the numbers start matching up in the original DAC_GenerateWaveform_TriggerHW example code?

 

Thanks!

not sure what you mean by "as usual" ?

Some ST examples do have .ioc files (ie, they were created using CubeMX); some weren't - see previous discussions, eg here.

The clue to which is which seems to be here.

These projects just weren't created using CubeMX at all - you can't re-create something which wasn't ever there.

Again, some examples do have .ioc files; some don't - so neither having nor not having an .ioc file is "usual".

There are plenty of examples which do have .ioc files, and plenty which don't.

Hello @JFlowers ,

The following article Getting started with DAC will help you on how to set up the DAC as wave generator in STM32CubeMX and creating a simple application to test the DAC.

@JFlowers 

"Since the STM32CubeMX .ioc file does not exist for the DAC_GenerateWaveform_TriggerHW example code (as usual)"

Please bear in mind that at time where STM32CubeH7 was released, providing ioc file with the examples was not the policy. 

That policy started after with newest products and Cube-HALs of older MCU families (F1, F2, F3, F4, F7 etc ..) don't contain ioc files in their examples.

I can understand this. Thanks.    I cannot/will not believe that "plenty" is equal to zero.
