Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Radio data integration: Added functionality for displaying radio data as debug message. The USART3 has been configurated for receiption and a function for the visualization of the data has been added to the demo unit (draft implementation). For activation the radio as well as the logger functionality needs to be activated via compile switch. Note that at the moment bluetooth and radio DMA may not be operated in parallel.
