This project is cool, and I use it on my stm32f407 device. but I can't find any sample and resource about serial port DMA and SPI DMA support. our cool project support DMA or not? Should I can get some sample about these? Thanks!

DMA isn't yet supported, there is some work being done in #88, but I'm kinda busy with some other stuff at the moment, I also want to see how rust-embedded/embedonomicon#64 goes before finishing it, since we will probably have new traits to work with.
