TI C2000 Delfino - Setting up a software SOC trigger for an ADC in Simulink

Hi, I'd like to know how to set up a software SOC trigger for an ADC in Simulink. Page 1564 of the TI Delfino Technical Reference Manual (Rev. I) states that to trigger this interrupt, we should write bits to the ADCSOCFRC1 register. It seems fairly straightforward to do this in Code Composer Studio by writing to a particular register. However I am unable to find documentation for how to do this in Simulink.

Could you please advise me on how to set this up? Should I be using the Memory Copy block to write to a particular address?

For reference, here are the block parameters for the particular ADC in question, which I'd like to trigger using software. Note the "SOCx trigger source" parameter says "Software".

Hi Aryaman,

Please refer to the following pages which explains or showns how to configure SOC for ADC.

Hello,

Is there any current documentation that explains how to set up the software trigger for ADC in Simulink?

The links provided say "The page you were looking for is not available in this version of the documentation."

my main question is wether I need to use the MemoryCopy Block to write the ADCSOCFRC1 bits like said in the Technical Reference Manual or is there another way?

I had the same question, check out this video:

Read ADC sofware triggered

The suggested documents:

Won't answer your question directly.

Cheers!
