Re: Deploying old XAML
It seems like if I change the package name every time I make a change it works.

Deploying old XAML
Hi,
I have two projects in Visual Studio 2015. When I first deploy them they work fine, but then when I make modifications to the XAML, I see them locally in the designer but when I deploy again the old version shows up on the pi. Anyone know how to fix this? Clean, Rebuild, restarting, nothing works.

Re: Trouble connecting to the MCP4131
I reached out to Gordon Henderson, the developer of wiringPi, and he said this: That code bit-bangs the SPI port rather than use the kernel driver. It will leave the pins in the wrong state, so if you run the C program using wiringPi AFTER the python one, then it won't work correctly. Try rebooting ...

0 Is the channel which I assume is CE0. Most of the examples I've seen (for wiringPi with other chips) just check the return value to see if the device could be opened, like this one:

Re: Trouble connecting to the MCP4131
Hi Joan, I was able to get your code to work once I realized it was using CE1 and not CE0. Thanks, now I know my wiring is correct! Now I'm having trouble connecting in c, which is what the rest of my project is in. Here is my wiringPi code, can anyone tell me what I'm doing wrong? The voltage never...

Re: Trouble connecting to the MCP4131
Thanks Joan,
That's not working either, though interestingly now the wiper is stuck at 4.6V for all of my scripts including yours. Maybe I'll try just one MCP chip directly next. You just work with the chip at 3.3v and don't use a LLC correct?
Thanks again--

Re: Trouble connecting to the MCP4131
Thanks Joan! Ok it must be my wiring because I tried your code, I see it cycling through but the voltage on the wiper output is still always 2.4. Here are some photos, but it's a mess: http://imgur.com/a/CTlsz Here is my circuit, I have two MCP4131s and two Sparkfun BOB-12009 logic level converters:...

Re: Trouble connecting to the MCP4131
Thanks! I'll give that a shot. It's not the length of my wires is it? I'm using 6" female to female connected to 6" male to male jumper wires to get to the LLC, and then another 6" to get to the chip, so 18" total. The voltage drops from 5V to 4.7V at the chip, but that should st...

Trouble connecting to the MCP4131
Hi, I'm having a heck of a time connecting to a MCP4131 via SPI with a raspberry pi 3. I can connect to it fine with an arduino, the code is simple: digitalWrite(CSPIN, LOW); SPI.transfer(0x00); SPI.transfer(50); //number between 0 and 127 digitalWrite(CSPIN, HIGH); The MCP4131 expects 16 bytes: 6 b...

Re: Modifying a 3.5" car display for USB power.
I have the same display as Kronalias. Thanks for your video Kronalias. I saw a comment by Patrick on this blog (http://www.wisegai.com/2012/11/29/raspberry-pi-using-a-3-5-tft-car-monitor-optional-powered-using-usb/ ) that says he connected a 2S 7.4v lipo to the display, and it was enough voltage eve...

Ethernet dies with midi controller
Hi, I'm having an issue with my PI where the ethernet dies when I plug in a small MIDI controller. Once the MIDI controller is plugged in I can no longer connect to it via ssh on ethernet. Here is the controller I'm using: http://www.amazon.com/Akai-Pro-LPD8-Ultra-Portable-Controller/dp/B002M8EEW8/r...

Re: PI as a wireless midi controller interface
That sounds awesome, I'm trying something similar with the LPD8 and using it to control lights. I also am trying to get the PI to sync to Traktor with midi time code and IPMidi but am having trouble with midimulticast.

Re: Setup PI to work without monitor (debian image)
Hi, Thanks for this. I couldn't get init.d/vncserver to keep running on reboot. I had to run this: sudo update-rc.d vncserver defaults 99 That sets it to run on reboot, but at a low boot order, per these threads: http://www.debian-administration.org/articles/28 http://www.abdevelopment.ca/blog/start...
