Re: Using atan2 on the cRIO
Hmm... We used the atan2 function in the 2010 bot with no problems. A quick check on the bot shows both an atan and an atan2 in the symbol table. From the netconsole prompt:
-> lkup "atan"

Re: Enhanced I/O in 2015?
Well, we already have rearranged things. But, that stil doesn't address the issue of being able to create a dedicated IO controls box to make the game more playable. We're just looking to see if in...

Re: Enhanced I/O in 2015?
If it were just one LED, we could certainly do that. But, there are a number of such LEDs for different subsystems (e.g., ball ready to shoot, within range for a shot, ball jammed, etc.). Not...

Enhanced I/O in 2015?
Hi beta testers!
Do you know if there will be an EnhancedIO in the 2015 control system? We've typically been using the Cypress board for digital outs, i.e., status LEDs on our IO controls box. ...

FTPing to the cRIO is pretty straightforward. Open a session...

Re: Which Linux distributions do you use?
+1 for Mint. I've used Connamon, Mate, XFCE and currently KDE. XFCE is great for a lower powered laptop. KDE really requires GPU acceleration to make it fly with lots of eye candy.

Re: New REQUIRED version of C++ libraries
Hi Greg,
Yeah, I could believe that. Given the number of packets in normal driver station comms, I could see that there's likely a fair amount of 802.3x flow control packets if the switches are...

Re: Android Controll System
So, did this project ever make any progress? I'm very curious as to being able to attach Android or Arduinos to the driver station. We need a lot of I/O for this year's design.
TIA,

Re: Multiple cameras
I 2nd the notion of watching your frame rate to the driver station. They're bandwidth limiting the comms to only 7 Mbps this year. 320x240x30 FPS is 1/3 of your bandwidth without some serious...
