DMA to GPIO output pins

Question asked by gorge on Jun 28, 2016
Latest reply on Jun 30, 2016 by gorge
I wish to transfer a large array of data to 8 output pins that are all on the same port. E.g. a 500 element 8bit array where each bit of each element represents the pin status.
So 500 independent transfers to the port would be required.

I have been looking through the examples that ST have but none of them seem to do this.
There seems to be a lot of 'DMA to PWM' examples which transfer to a pin that has a timer connected to it but this isn't useful to me since I want to transfer to a whole port.
How would I do this? Are there any examples similar to this which I could modify to my need?

Thanks
