expanders_init.h - An embedded CNC Controller with rs274/ngc (g-code) support
|
|
|
|
Calls the init function of enabled expanders, this file is typically included early in driver.h
|
|
io_expanders_init() should be called at the end of the drivers driver_init() implementation,
|
|
just before the driver claims ports.

These are NOT referenced in the core grbl code
