I'm new user running a STM32F767ZI Nucleo board.

I need to build very simple application that copied array[2] to GPIO Pin (PC6) by DMA in "memory to peripheral" mode.

I interested to activate DMA in two modes:

a) Don't use timer (memory to GPIO by DMA polling)

b) By timer activation

I found exact examples for both of modes in STM32F4-Labs.pdf (Labs 6 and 17) , but these example don't work in STM32F767ZITx with GPIO periphery ....

I am looking for working example...

Thx,

AlexP

Did you modify those examples? You need to use DMA2.

Yes. I use : TIM1_UP DMA2 steream 5 memory to peripheral
