Hi,
The ShiftReg component states that it is possible to use via DMA, but I can't find any examples. Could someone point me at an example please?
I'd like to setup an array in memory and DMA the data to the Shift register for output to a port pin.
Thanks.

Thanks.
Yes, I've seen this post and now have a couple of examples. It seems there interface has changed or maybe it's the difference between PSOC-3 and PSOC-5 versions, but it's not easy to piece together a working example 🙂

Thank you for the examples - much appreciated.
Took a quick look and it seems to match what I have, so very good as a confirmation!
Found that writing to the output register caused glitches, so needed to write to the FIFO, but then needed a load signal and this needed to be at least one clock width wide, so ended up putting in a PWM.
Thank you.
