STM32F103 How do I DMA Transfer Memory to GPIO with external Clock

Hey all,

I am trying to transfer Memory from an STM32F103 to another Processor by GPIO over an 8 Bit Bus. I am working with CubeMX HAL Library and trying to set up the transfer so, that it is putting data on GPIO when an external clock is supplied. I am failing to set up the Timer to trigger a DMA request. Does anyone have an example that shows the setup code of what I am trying to achieve?

I can do manually triggered DMA Transfers on every Timer Interrupt, but the overhead of manually triggering is too big.

 

Thanks
