annotate examples/d-box/FIRfilter.h @ 373:3bed6b09223c
prerelease
Updated NE10 library to the latest version; needs a corresponding update to the /usr/include/ne10 header files on the SD image. Updated examples to compile against new version, and reordered D-Box channels to account for new PRU-based DAC channel reordering.
