I have the example from the library showing DMA (mem to mem) working with the following initialization:
/* Configure DMA Stream */
DMA_InitStructure.DMA_Channel = DMA_CHANNEL;
DMA_InitStructure.DMA_...

I'm working with the Nucleo F446RE, and the project that I created using the STM32 Workbench as well as all the standard library files include the stm32f4xx.h file rather than the stm32f446xx.h
I noticed...
Posted on July 29, 2015 at 16:14I've been developing on a NUCLEO-F302R8 but a recent change to the scope of the project has left me with a requirement for 40kB of RAM, and the part on this dev board only has 16kB. What's the best way to expand my RA...

Hi All,
I'm configuring my DMA to transfer 48 bytes of data, and am triggering the DMA interrupt both on TC and HT events. Currently if I disable the DMA after the first interrupt, so I would expect to see...
Posted on July 20, 2015 at 23:34Hi All,I need to transfer a large amount of binary data to my STM32 and am trying to figure out what the best way to do this would be. The data throughput needs to be roughly 8Mbps. The device has USB so I was thinkin...

For whatever reason TIM8 doesn't appear to have a CC IRQn on the STM32F446
TIM8_BRK_IRQn = 43, /*!< TIM8 Break Interrupt */
TIM8_BRK_TIM12_IRQn = 43, /*!< TIM8 Break Interrupt and TIM12 global interr...
Posted on August 13, 2015 at 00:40I forgot to enable the NVIC, but that's good to know about the TIM8_CC_IRQHandler being separate.I guess I'll just adapt my code to use TIM8, but I still don't understand why DMA1 wont work for this. From what I und...
Posted on August 13, 2015 at 00:09Hmmm, for whatever reason this one works fine but if I switch to Tim2 it breaks. I'm trying to adapt TIM8 to work like TIM2 in my example with the output compare, but I'm not sure how to get the interrupt handler fo...

Thanks Clive, that's helpful. I just realized my SFR view wasn't working properly because Atollic hadn't linked to the correct .svd file, but I've got that fixed now and I see the transfer error flag set, altho...
