Implement M10 M11 to toggle anther 2 output pins

[Daniel Dumitru]

HEllo All,

I have assembled a custom made board implementing TinyG. I intend to drive a pick and place machine with it. 

Since I have pneumatic z axis I need to toggle another 2 pins in order to drive electrovanes.

I would like to implement M10 M11 M12 and M13 to toggle 2 new pins.

I was thinking to use pins PB4 PB5 but looking on source code it looks pretty complicated to toggle pins :
gpio_set_bit_on(FLOOD_COOLANT_BIT);
if (b & 0x08) { hw.out_port[0]->OUTSET = GPIO1_OUT_BIT_bm; }
this struct implementation and binding it’s not clear for me.
I need some help to drive port PB – pins PB4 PB5.

Could someone give me a hint how to implement it ?

Any help , example it’s greatly appreciated !

Kind regards,
Daniel
