This program uses the timers to trigger EDMA events. These events in turn trigger linked EDMA parameter tables to fill a ping pong buffer structure.Set a breakpoint on processbuff function. Then open two memory windows.Use ping as the address for one memory window and pong for the other. Then run the application. You ll note that the program bounces between the ping and pong buffers filling each with a value that comes from the source.-This program uses the timers to trigger EDMA events.
