Add function to maintain a minimum value seen of free memory. Add call to it in DCCWaveform interrupt handler (assumed to be the likely worst case for stack usage). Report this minimum value in main loop.

// CONFIGURATION:
|
|
// Configuration is normally performed by editing a file called config.h.
|
|
// This file is NOT shipped with the code so that if you pull a later version
|
|
// of the code, your configuration will not be overwritten.
|
|
//
|
|
// If you used the automatic installer program, config.h will have been created automatically.
|
|
//
|
|
// To obtain a starting copy of config.h please copy the file config.example.h which is
|
|
// shipped with the code and may be updated as new features are added.
|
|
//
|
|
// If config.h is not found, config.example.h will be used with all defaults.
