Hi,

   

I would like to trigger a DMA transfer when the ADC conversion is done, so reading the Scan ADC datasheet found on the beginning of the page 31 that the DMA Req Signal must be triggered with the eoc terminal, but i can't found that terminal anywhere on the datasheet nor the component configuration window.

   

Been reading that some Analog Coprocessor features are missing in the current PSoC Creator version, so i would like to know if this is one of them (missing eoc terminal).

   

 

   

Attached is a snapshot of the DMA Section on the Scan ADC datasheet.

   

 

   

Thanks in advance

Probably a mis-print for a new device.

   

The signals is

   

eos (end of scan, all active channels sampled)

Hi Bob,

   

That was the first signal i tried to connect to but Creator throws an error telling me that eos signal can't be used for triggering DMA (or something similar), there´s another signal: sdone, if i connect the DMA trigger to it i get no errors but i am not sure if it's the correct one, conversion takes a little more cycles than sampling.

   

I had read that the new Creator will come out until the next year, hope it doesn't take that long if this is an error 😕 .

I would suggest you to create a support case asap.

Here's the answer:

   

"In current version of psoc 4B, sdone signal instead of eoc should be connected to dma. This is issue in silicon and this will be fixed in upcoming version of silicon. Mention the customer to use sdone signal instead of eoc signal. Sorry for the inconvenience caused."

   

 

   

I do not now if sdone will trigger the DMA before or at the same time eoc would do it. will do some test.
