Hello,
I am using the TMSF28335 and try to configure the ADC and DMA sync fetaure, knowing that i am using INT_SEQ1 source as event.
Part of the initialization of the DMA is
DMACH1ModeConfig(DMA_SEQ1INT,PERINT_ENABLE,ONESHOT_DISABLE,CONT_DISABLE,SYNC_ENABLE,SYNC_SRC,
OVERFLOW_DISABLE,SIXTEEN_BIT,CHINT_END,CHINT_ENABLE);
Of course i aslo enable the continuois run and ovr seq for the ADC as mentionned in the DMA/ADC datasheet.
When i disable the sync feature, my acquisition ADC/DMA is working.
As soon as i enabled the sync feature the acquisition never occurs, although the INT_SEQ1 flag is set .
Is there any code example i can find to have an example for this ADC DMA sync feature?
My understanding is that this sync feature should use this INT_SEQ1 to trigger the synchornization.
For information, as soon as i force the sync (SYNCFRC bit enabled) , the acquisition occurs.
Meaning it seems the sync condition is not occuring. But i don t get why.
Regards
