Key steps to follow in order to be able to monitor a variable in FreeMASTER: 1. Connect to the target board using connection wizard using the connection method specified in `freemaster_cfg.h` 2. Make sure the variable that stores the ADC values is visible to FreeMASTER (if is automatically discovered if Target Side Addressing TSA is used on the embedded side or can be extracted from the project ELF file). 3. Use FreeMASTER GUI features: Variable Watch for numeric or Oscilloscope for visual data representation.
