SPAD.neXt

Hello everyone,
I've been struggling with something I am trying to build.
Basically as Saitek Backlit Info Panel is quite hard to find (especially at reasonable prices) I am trying to build one.
Architecture is quite simple I just need LEDs connected to arduino and need to turn them on when a condition is true.

I am currently using another Arduino Leonardo configured as Joystick for inputs and it works like a charm, so I am not new to all this.

What's difficult to me is to find a way to send an input to arduino leonardo (currently configured with Joystick.h library) from Spad.Next.
For example, when a condition gets satisfied like a LOW FUEL, for example, I need to turn on a led. Simple as that.

In the Saitek Multipanel this is simple as I can use the "Change button light" function (which I use now for stall warning, etc... but it does not work very well).

How can I achieve this with Arduino the easiest way? Possibly using only spad.next..

Thanks in advance.

Hi,

As far as I know, the Joystick library is one-way communication.
Try setting your Arduino up as a serial device for two-way.

Do you have the complete edition of Spad.Next and access to that member section?
Reason I ask is there is a thread in that section where a few members kindly pointed me in the right direction.

Pete.

Hello Pete,
thanks for your help, yes I do have Spad.Next, not the full version though. I will try to search in that section.

Thank you.
