Send Additional Signal to PC via IONICUBE

drumsticktt · 7 June 2020 19:58

Hello,

I’m working on a project that would require me to send an additional signal from a button on a haptic feedback stick rig to the PC that we’re using as a controller. Is there any way to use SimpleMotionV2 to poll the state of an unused pin? I’m using an IONICUBE with four IONI Pro drives, but even one pin would prove sufficient for my purposes most likely. I’m just trying to avoid the use of an additional USB if possible.

Thanks

Yes, you can poll one variable to read most of digital inputs. See:

github.com

GraniteDevices/SimpleMotionV2/blob/master/simplemotion_defs.h#L405




/* used only for device production testing, not recommended for normal operation, therefore not publicly documented */

#define SMP_GPIO_LOW_LEVEL_ACCESS 102

	#define SMP_GPIO_LOW_LEVEL_ACCESS_SET_PIN_MODE 0

	#define SMP_GPIO_LOW_LEVEL_ACCESS_WRITE_PIN_OUTPUT 1

	#define SMP_GPIO_LOW_LEVEL_ACCESS_READ_PIN_INPUT 2

	#define SMP_GPIO_LOW_LEVEL_ACCESS_READ_ADC_PIN_INPUT 3

/* used only for device production testing, not recommended for normal operation, therefore not publicly documented */

#define SMP_GPIO_LOW_LEVEL_INPUT_VALUE 103



//each DIGITAL variable holds one bit for each physical digital input

/*SMP_DIGITAL_IN_VALUES_1 on GD motor drives:

 * bit	physical input

 * 0	GPI1

 * 1	GPI2

 * 2	GPI3

 * 3 	GPI4

 * 4	GPI5

 * 5	HSIN1

 * 6	HSIN2

 * 7	Analog In 1 as digital value

I hope this helps!
