I am trying to use DMA memory scatter gather mode for data transfer. Are there any examples that use scatter gather mode to transfer data between adc14 channel and an array?

    Hello Yogyata

    There are no examples currently available for scatter gather in example data base. However I have an example to do the same for one of my own applications. If you can describe what you plan to do, I can see if the example that I have is suitable or if some modifications can be suggested.

    hello amit. Thanks for your reply. I realised I wont be needed scatter gather immediately. I am trying to sort some other issues; using dma ping pong with fatsd. Do you know if i can use the fatsd functions like fopen, fwrite, etc. in the main() fucntion and completely avoid using a task fucntion (taskfxn)?

    thanks!

    Hello Yogyata

    Avoiding a task will prevent use of the SDK's feature to provide the threaded application use, such that whenever a data is available to be written, then any task can post it and the write thread can allow for correct resource alloaction
