Stack Length 2

window while each line now ends with a "NL," New Line. Useful in testing multiple process
flow paths of a cog's work order.

Desc formatted properly in SPIN code.

One's top level SPIN code may look similar to the following:

VAR
long TestStack[32] 'a stack of longs used by delay routine

OBJ
Stk : "Stack Length 2" 'Include Stack Length Object

PUB public_method_name

Stk.Init(@TestStack, 32) 'Initialize reserved Stack space (utilized below)

cognew(Toggle(16, 3_000_000, 10), @TestStack)
waitcnt(clkfreq * 6 + cnt) 'Pause 6 seconds
Stk.GetLength(30, 9600) 'Transmit results serially out P30 at 9600 baud

cognew(Toggle(2, 19_000_000, 11), @TestStack)
waitcnt(clkfreq * 10 + cnt) 'Wait ample time for max stack usage, 10 seconds
Stk.GetLength(30, 9600) 'Transmit results serially out P30 at 9600 baud

cognew(Toggle(81, 2_000_000, 500), @TestStack)
waitcnt(clkfreq * 10 + cnt) 'Wait ample time for max stack usage
Stk.GetLength(30, 9600) 'Transmit results serially out P30 at 9600 baud

PRI Toggle(x, y, z)
