Contributions summary:Hubert implemented a DMA-based SPI slave for the SAM4L microcontroller. They created and tested examples for SPI master and slave transfers, including communication with devices such as an SD card. The user addressed and fixed bugs in the SPI driver related to baud rate calculation and transfer progress and updated the code for more accurate frame handling.
