how to configure 16-bit GPIOE port for DMA access
Posted: Thu Jan 30, 2014 6:58 am
I am getting ready to set up DMA access to the 16-bit I/O port GPIOE.
I am going to set the i/o port as output using the config file, but
I am not sure how to specify the data register to the DMA function.
It looks like this may work, but I am not sure....
Thanks

Code: Select all
// Set the destination address
dmaStreamSetMemory0( STM32_DMA1_STREAM5, GPIO_PORTE->ODR );
