Chaper 3 - Touchpad Example. Task watch dog triggered when detecting touches #5

Build the touch pad example, also built directly from the git hub repo. issue persists in both cases.

Issue appears to be triggered by calling printf with formatted data in the monitor task. This is specifically when there's formatted data. If I remove the format specifier and other arguments, watchdog is not triggered and the output is displayed.

Environment:

HW : Espressif ESP32 Dev Module Dev Environment : VS Code + Platform IO on Max M1 Max

Increasing the stack size seems to resolve the issue for me. Please can you update the source for the sample increasing the stack size of the monitor task to a higher value. I used 4096.
