hi,

how can we trigger our ADC in TM4C123g using timer instead of processor ? and one more thing how can find the default sampling frequency of the ADC ?? and how can we reset it according to our needs?

I have attached an example project that uses Timer0A to trigger ADC0 Sequence 0. The sample frequency is set by the function TimerLoadSet() on line 168 of the file main.c. This example also uses the uDMA to move samples from the ADC into one of two ping-pong buffers. Use the Code Composer Studio "File" -> "Import" function to import this project into your workspace.
