I’m working on my screen masking system, and it will be controlled by a linear actuator. The LA has a pot so it can have programmable positions for the common aspect ratios. I am controlling the LA with a controller by the same company that makes the actuator, and controlling that with an iTach CC. I just got the setup working last weekend with the up and down motions and the preset positions. But I want something more…
I would like to input the pot reading of the LA into iRule so that I can have a readout on my ipad of what the current aspect ratio is at any point. I am new to using the iRule software, and have searched for a while now trying to find information on doing this, but I have come up with zero results. From just reading the abilities of the different iTachs, it looks like it may be possible to put the input into an iTach IR, but I cant find any info on whether or not the inputs are analog, or if they are just an on/ off type of input. Please, someone tell me there is a way to do what I am trying to do..
And then, IF there is a way to get the input into iRule, how do I set up a screen to display the aspect ratio? I can easily calibrate the numbers and give the slope and y-intercept of the resistance vs aspect ratio, that’s not a problem. But the actual GUI is where I will need help.
