Hi,
I am working on a project where i need to read a GPIO port at a fixed frequency (a couple of MHz) and I want to use a DMA triggered by a CTIMER to achieve that.
All of which seems totally possible according to reference manual (UM11126).
Now, when i read chapter 22.5.1.2 is says i need to configure DMA_ITRIG_INMUX registers.
The (big) problem is that I can't find this register anywhere. Nor in the reference manual's registers section, nor in the register definitions *.h file.
Is this an error?
Are there any examples using hardware trigger?
Thanks,
Solved! Go to Solution.
Nevermind, i found the answer on chapter 18 (INPUTMUX).
Now, i'm still interested in an example if someone has one though...
Thanks!
Hi, Ibrahim,
I have not found the example that the external signal triggers DMA to transfer in SDK package.
I will try to develop an example later if I have time.

That would be great! Thanks
