I'm working though the grlib_demo supplied with SW-TM4C-2.2.0.295 and I see that in grlib_demo.c starting at line 1070, the uDMA controller is enabled and set up.
Yet I can find no reference anywhere else in that project to the DMA controller. I commented-out the four lines for the uDMA set-up and the demo still worked, as far as I can tell.
Should we assume that the uDMA enable is just crufty leftover from some other demo?
Thanks !
