Re: UWP vs APK on Raspberry Pi3

You are asking a question of "Which tastes better, apples or oranges?" The real difference between choosing Windows IoT or an Android OS for your Raspberry Pi will come down to which one meets your needs. Do you have a prepackaged application to run? If so, you have match the OS to that package. If ...

Re: Windows 10 Iot Core : The LCD screen suddenly turn to White and Windows Iot Hang up

@fruitoftheloom, that sounds like power issues. I had similar issues in one setup where a power supply couldn't supply enough power for long enough. Most micro-USB power supplies are probably not going to supply enough power for the Pi and a USB powered display, or the Pi may not be able to consiste...

I2C errors with official display connected

I asked this question under the display forum and basically the response is that Windows isn't doing things right. https://www.raspberrypi.org/forums/viewtopic.php?f=108&t=198130 I am getting lots of slave not found errors from I2C devices but only when the display is connected to I2C1 (pins 3 & 5)....

Re: I2C errors when display is connected

Thanks for the responses. Unfortunately the Windows IoT forums push down the path of using device 0x45 on I2C1 and the mailbox implementation right now is only C without a C# implementation, and reviewing it I have doubts that I can make it work in C#. At the very least I have a better idea of what ...

Re: I2C errors when display is connected

On the Raspberry Pi 3 the extra pins are still required to control interface with the touchscreen if you want to control features such as brightness. So I have the 5v, Gnd, SDA, and SCL pins connected plus the ribbon. WIthout the SDA and SCL pins, trying to control the touchscreen will result in an ...

Re: I2C errors when display is connected

To clarify further, I do not even have to have code connecting to the display's I2C, just having the display physically connected is enough to cause the problems.

I2C errors when display is connected

I have recreated this with multiple PIs, displays, and devices so I can rule out individual hardware as an issue. I am finding that when I have the display and another device connected to I2C that the second device gets lots of errors (intermittent but frequent) that it cannot find the I2C device. I...

Re: Windows IOT and Display Backlight Brightness

That does not work for me. "Slave address was not acknowledged." 1) Are you on a Pi 2 or Pi 3? 2) Are you using just the ribbon to connect, or are you using the pins as well? I'm hoping we might be able to pick out why it works for some people and not others. I am on a Pi 3 using just the ribbon cab...

Keep in mind that voltage drops over distance, so since you are using a single supply you may have too much voltage drop on some devices.

Re: Short range I2C woes

Can you try not connecting the power line (just the 3.3v or 5v wire) and powering it locally on both ends instead? You will still need a connected ground so that there is a common reference for the clock and signal.

I've found that a lot of I2C & SPI devices plug in with varios crimp based connectors such as molex and JST, however I haven't found anywhere that I cna buy either the plugs pre-assembled with header pins, or the pieces to do it myself. I tried pulling some pins from extra long headers, but they don...

Does anyone know how to setup Windows IoT on Raspberry Pi 3 as an iBeacon transmitter? I've seen that it has been done with the Raspberry Pi 2, so hardware doesn't seem to be a problem, just no clue if/how on Windows IoT.

Re: Raspberry Deployed App - Is stopped automatically.

Try using a UWP project instead of an IoT project, then add in the IoT Extensions. The main UI form will load up (even if you are headless) and keep the application open unless you encounter an unhandled exception.

I believe there is one in the DSI port, it may simply be an addressing issue, or perhaps Windows IoT has it locked and is hiding it.

Re: How to make running leds with Windows 10 IoT uwp c#

You initialize your variables inside the timer elapsed method, so you are never able to advance. Your counter variable needs to be scoped outside the method (as a private variable) to avoid being reset with each elapsed event.
