[libopencm3-devel] DMA convenient functions (STM32 F1)

[Stephan W. <ste...@ka...>]

Hello,

I was working on some additional convenient functions for the DMA part
of STM32 F1.
Additionally, I found an error in the header file, where the mask flags
for MSIZE and PSIZE are defined wrong (both 0x02, should be 0x03).

I attached a patch to 4fbd42148ad61642278344ba13615b56ffa3284e.

It adds disable functions for the DMA modes and allows to get and set
the flags' status also by function calls.
The addressed mask values are both set to 0x03 now.


Sincerely, Stephan
