Feeding DFB Assembler with DMA

[Anonymous]

I am wanting to feed ADC data into the DFB assembler using DMA but when I open the "DMA Wizard" The DFB doesn't show up as an option.

If I add the Filter block instead of the DFB assembler then it shows up fine, but for my application I need to use the Assembler. Is there something special I need to do so that the DFB assembler can accept transfers from the DMA?

Note:

I have tried attaching a DMA channel to the DFB's DMA_REQ terminal and even then it doesn't show up as an option in the DMA Wizard.

The DMA Wizard only works for few periperals, you should do the DMA configuration manually. This thread might help you: DFB to average ADC convertion results [Kit 059]. Let me know if it helps.

Check the MagnusLundin​ messages.

Thanks. One of MagnusLundin 's posts has a link to his blog which has more useful information about the DFB.
