I am using TIM2_CH3 configured for a DMA1 request on Stream1_Channel3. On Output Compare I would like TIM2_CH3 to trigger SPI1 to begin a DMA2 request on Stream5_Channel3.
How do I associate the TIM2_CH3 event with SPI1 DMA2 using Stream5_Channel3 (for example)? I don't understand the usage of TIM-DMABase in TIM_DCR register. Is this only to perform a DMA between a TIM register and memory?
