Watching Symbol Values Change

Edit the Code

Click the “Finish Debugger Session” icon .

Currently pot_value is a local symbol. To make it a global symbol, declare it before main().

#include "mcc_generated_files/mcc.h"
uint16_t pot_value;
/*                         Main application
 */
void main(void)

Then remove uint16_t from the line that contains the first usage of this symbol.

    while (1)
    {
        // Add your application code
        pot_value = ADCC_GetSingleConversion(POT);

Place a breakpoint at this line and again click the “Debug Project” icon . The program should halt on this line.

Create a New Watch

To create a new watch:

1.Select Debug>New Watch. The New Watch dialog will open.
2.Enter a Watch expression, in this case pot_value, and then click OK. The Watches window will now appear on the desktop with the symbol.
