Exercise 8: Blinker2.spin – Many Objects, Many Cogs
Now let’s make a new object that takes advantage of the enhancements to Output to use many
cogs for many parallel processes. Here’s the code:
Example Object: Blinker2.spin
{{ Blinker2.spin }}
CON
OBJ
PUB Main
{Toggle pins at different rates, simultaneously}
PUB NextObject : Index
{Scan LED objects and return index of next available LED object.
