OpenPNP plugin

Under development. Adds 5 M-codes to allow grblHAL to be used for OpenPNP machines.

• M42 P- S- Set digital output. The P-word must be a valid ioport number, see below. The S-word is used to turn the output on or off. Use 0 for off, > 0 for on.

• M114 <P-> reports current position. The P-word is ignored if provided.

• M115 Reports firmware information.

• M204 <P-> <S-> <T-> Use S- or T-word to set acceleration for all axes except the linear axis (Z-axis), use P-word to set it for all axes. If the word parameter is 0 acceleration is reset to default values.

• M400 Waits until the motion buffers are cleared and motion stopped. Same function as G4P0.

Dependencies:

Driver must have one or more ioports ports available for digital output to enable M42 use.
