G474 problem connecting COMP1 output to HRTIM event4 source

[jose luu]

Hi,

What am I missing ?

The connection to the event source is grayed and non selectable, see screen copies of the configuration below.

 

[AScha.3]

i tried ...but: deselect external in comp

+ not select ext

-> if event4 not possible, use other event (1 or 2...)

try it.

I initialized COMP2 and tried to select it: it is still grayed, -> something is preventing the selection.

On your side, it seems that you are starting from an already complex configuration (since PA0=COMP1_OUT was busy), could you try recreating a project from scratch, only selecting the processor G474 and configuring COMPx and HRTIM ?

Also I am using the latest cubeMX: 6.9.2, which version do you have ?

[AScha.3]

ok... (in ide 1.13.1 ) + cube G4 1.51 (actual download) for G474RET6 :

i just set master timer on, not select any "external" in comp and hrtim event .

+

in your pic -> timer D has red cross -> you set something wrong there, clear this ! (cube shows you message, when mouse over the wrong item there , whats wrong)

Could you attach your .ioc file so I can peruse it ?

here... 🙂

just rename txt to ioc . (ioc upload not allowed here - maybe STM dont know, what this ioc should be ...)

Thanks, resolved: 

 

 SOLUTION SUMMARY:

 the trick is to  *NOT* select "External event 4" in the upper "EXTERNAL EVENT LINES" topic but *enable* "External event 4" in the lower "External Event Configuration" pane.
