M670

Parameters

Pnn:nn:nn... - List of logical port numbers that bits 0, 1, 2... control (supported in RRF2.x and earlier)
Cnnn - Used to specify the pin name(s) to be controlled (supported in RRF3), see Pin Names
Tnnn - Port switching time advance in milliseconds

Notes

In RRF3, the P parameter is removed. Use the new C parameter to specify the pin names to be used.

Example - old code:

M670 T5 P220:221:222

New code:

M670 T5 C"sx1509b.0+sx1509b.1+sx1509b.2"

RepRapFirmware 1.19 and later provides an optional P parameter on the G1 command to allow I/O ports to be set to specified states for the duration of the move. The argument to the P parameter is a bitmap giving the required state of each port. The M670 command specifies the mapping between the bits of that argument and logical port numbers. Optionally, the T parameter can be used to advance the I/O port switching a short time before the corresponding move begins.
