Hi, I wana to get data from CMOS image sensor by using DMA in stm32f10x, but I need use two external interrupts to start get data via DMA.
One
of them
is used
to
notify
the start of the
frame a
nd the other
is used
to indicate the
beginning of a line. is it possible to use two external interrupts with DMA?. because the DMA dosent use the CPU. would you guide me please?

Not easily, you'd probably need to go through a TIM unit to generate DMA requests. You should perhaps look at the DCMI interface on the F2 and F4 parts.
