Hi, thanks for your library. I'm wondering if it should possible to send data by a DMA channel. This could be very useful to send long string of data without unwanted holed (for example to driver LED strips ..) Thanks, regards

Hello, thank you for your request. Generally this would be a good idea but it also means to to find a free SPI capable DMA channel. So the dts/dti needs get adjusted. It would be great, if you would like to have a look into that. Meanwhile you can find the hardware manual rather easy. And the kernel driver code should also be a good first entry.
