// User add-ins can be created when you want to do something that

// HAL subsystem.
// Example: The function will be executed once per second and will display,
// on screen #3, the first eight entries (assuming an 8-line display)
// from the loco speed table.
// Put the following block of code in myHal.cpp OUTSIDE of the
// halSetup() function:
