I'm new to the Photon solution (edited by ScruffR) and have an application in mind that requires 2 devices to use DMA to offload CPU cycles. I was hoping I could write my own library using the STM32F20xx Peripheral library. If this is not available I can code at the peripheral level as well provided the compiler environment supports a mix of .ino and low level .cpp or .c files (the library).
Will the compiler permit low level hardware register access and where can I find the peripheral library for the STM32F205 used in the Photon?
Thanks in advance,
Joe
