Triggering on Power Up?

Are you using self-boot? If so, you can use the manual EEPROM generation method and put your own custom write commands at the end of the sequence.

Yes I am using self boot. Just need to be able to have the program know when power up happens, do somthing then and never again.

Any way to squecne different piecs of code? Like I want to have an initiallization step then run the main code until powerdown.

Within SigmaStudio this would be tricky. The core is really meant for audio flow-based processing, not sequenced steps.

You could possibly put something together using cells from the logic library (one shot, zero cross detect, toggle, etc...) along with index selectable multiplexers to get some kind of sequenced processing together, but the core wasn't really designed to do that so it's not intuitive or easy.

I thing the EEPROM write sequence is probably your best bet.

For example, if you wanted a chime generator to activate on power up and never again, you could just include the chime activate command as the very last step in the selfboot sequence.

Hey Brett, any way you could give me a couple of examples of what a custom write command would look like in the Sequence window.

I understand to right click and add write command, but I don' t understand how I find out what to write in the boxes of that new write command based on what I want to do.

This could be VERY helpful to me so any help you have would be much appreciated.

Thanks,

Jason

It's actually easier to do the following:

Clear the capture window.

Link-compile-download your project.

Click-drag the contents of the capture window to the sequencer window, as explained in the link I posted above.

Clear the capture window again.

Now, click the controls in the schematic tab to make them do what you want. For example, if I wanted to turn on a sine tone, I would click its checkbox so it turns on.

The write commands associated with this action will appear in the capture window.

Click-drag those write commands over to your sequencer window so they come at the end of the sequence you created.

Now follow the steps in the link above to export the EEPROM file and download it to your EEPROM.

Thank a lot Brett. That makes total sense. I'll give it a go!
