Setting Adc Clock Speed

Other Parts Discussed in Thread: HALCOGEN

I am being tasked with setting the ADC Clock speed via software. I do not think it is directly set-able but would appreciate any advice I can get on this issue.

    Hello Nolan,

    The easiest way to modify the ADCCLK setting is using Halcogen see the clip below:

    If, however, you want to do without Halcogen, there is a prescale register input that sets up a divider for VCLK1/(Prescalar+1) = ADCLK. Please reference teh ADC register section of the technical reference manual for more information. Also, minimum sample and conversion times are specified in the datasheet so care must be taken to choose settings that do not violate the specifications stated in the datasheet.
