Lesson 3 – Setting Up the Digital Capturing
335
For Selective Capturing:
• You should use a designated ‘capture’ device cycle and also a
designated ‘do not capture’ device cycle in the vectors to
determine at which vector data is to be captured and at which
vector not. How to set up such device cycles has been described
above.
The figure below shows an example of a vector label for Selective
Capturing at the serial output of an ADC (ADC_D1 pin) with the
cap and nocap device cycles used.
Vector Label for Selective Capturing
In the vector label shown above, only 64 bits of data get captured,
while 3072 bits do not get captured.
Settings for Digital Capture
The Digital Capture settings define
• the digital pins to be used for capturing
• which capture mode to use (Standard Mode or Double Mode)
The Vector Editor provides the menu D
IGDATA to enter Digital
Capture settings, and to set up vector variables.
