Hello,

I am trying to set ADC synchronised with PWM module, and DMA opperative with ADC.

The block ADC for C280x/c2833x family, at the library browser, has supposedly available the option 'Use DMA (with C28x3x)'. However, when it is included in a project this option disappears. ¿How can I set the DMA with ADC then? Should I configure DMA in Configuration parameters settings? If that is the case, what would be the correct configuration?

Thank you,

Francisco.

Hello,

thank you for your answer. This example is not available as far as I know, or maybe I am searching at the wrong place. The command to open that example returns error because matlab cannot find it.
