\subsection{sampling time}
|
|
The first experiment needed to run was fo selecting an optimal number of cycles for which the adc will probe the to it at that moment connected pin.
|
|
|
|
In this case the uncalibrated measurement of our input voltage was taken as example, and repeated with each of the possible 8 settings of the in Firmware used value.
|
|
|
|
The resulting errors can be seen in figures \ref{sampleticks1} and \ref{sampleticks2}
