  hi @renaud I can't seem to make sense of why your python installation will not instal pyserial.

  From the output you provided:

  Reading http://pypi.python.org/simple/pyserial/

  The link works - so easy_install should be able to find the package.

  Well, perhaps you need to upgrade from Mavericks to something newer - or you could try to install pyserial manually here: Pyserial

  Hi @james-a-shepard I share your wish for a capacitive display. We would also really have liked a capacitive display. However, the price for a capacitive display to use in Mono was too high for our price tag.

  When we got the Kickstarter funding, we had a lot of talk and worked to find a reasonable priced capacitive display. Unfortunately there were no good options. So we had to go with resistive.

  I hope you will still be able to achieve your planned ideas - even though the display is resistive. Can I ask what your plans are? Maybe I can help answering any questions, that arise.

  Happy hacking :-)

  On MacOS, you install can use Homebrew to install Atom (and a lot of other things), which will setup your search PATH

  $ brew cask install atom

  @malaire We are rolling out a version 1.7.1 in the next day or two, that marks the package modemmanager as a Conflict. This means it must be uninstalled before openmono can be installed.

  We think this is the correct approach, because it uses the dkpg system to document the relationship. Also, it is left as a user choice. We want to avoid removing packages from a users system by default.

  Hi @walkerm88,

  I don't know why this happens. However, I have some suggestions of course.

  First a little background on Mono serial port and drivers. On Windows we do not use any third-party driver - not even Cypress' driver. What we do is install a INF file that specify our USB CDC Serial port with the systems default USB CDC driver - which is provided by Microsoft.

  In the Device Manager you should be able to confirm that by clicking the tab Driver, like this one:

  The driver provider should be Microsoft - not cypress or anything else.

  If not, you can try our dedicated driver installer package (that installs the INF file) here.

  I hope inspecting the driver configuration in device manager sheds some light on the issue.

  Is there any way to detect what mode Mono is in?

  I measured these with Log4.USB data-logger (another great KickStarter project) which has 0.1 mA accuracy. I usually got 1.3 mA average in sleep mode but sometimes more.

  Exact number isn't that important here as I just wanted to detect the mode. (For battery life estimation USB current isn't that useful - current from battery should be measured instead.)

  I just received new replacement Mono, and after some initial testing I've seen no problems at all with sleep.

  So it seems that my problems were caused by faulty Mono. (I'll update title and first post accordingly.)

  Just unboxed Mono, just keeps restarting over and over again?

  @malaire said in Just unboxed Mono, just keeps restarting over and over again?:

  The example clock-app just run for 602 seconds and then reset. Is there a 10-minute timer somewhere?
  EDIT: yes, there is 10-minute timer, so at least Clock-app is now working perfectly (ref)

  Yes, this is intended to not drain the battery. In the framework it still is opt-in though. I recommend trying the newer apps like: https://kiosk.openmono.com/app/com-openmono-alarmclock

  @rhofer I am glad you were able to resolve the issue. I get that it is not visible to the naked eye, that mono is in bootloader. We wanted to keep the bootloader as small as possible, taking up a minimal amount of flash memory. Therefore it does not talk to the display or any other peripheral. It presents itself as a HID on the USB port.

  @malaire I have found the source of the issue on Debian, it the modem manager service that keeps resetting Mono by pulling the DTR low on all serial devices. I will post an more informative reply, in your original post.

  Hmm, it seems that what you see is an intermittent problem that happens on some networks. I will try to find a way to handle it better, stay tuned...

  @stoffera ah, that's 100% true that it only works once. I didn't think the relinking of the device would work while minicom was open, but that's great

  Mono SDK 1.2: hello_world app randomly waking up

  @khchiang said in Mono SDK 1.2: hello_world app randomly waking up:

  It likely could have been fixed by mono_framework commit 4f861348.

  Yes this issue was indeed fixed by this commit. The fixes will is present in our coming Release 1.3

  The reason for the spontaneous wake-ups is false-positive interrupts detected on the display and/or Wifi module interrupt signal. This happened when power was cut from the IC's, and their signal behaved randomly - triggering interrupts that woke Mono.

  The base on the jack connector is GND. We will release a schematic with pin names in the coming weeks. I will get back to you with a more fulfilling answer later.

  BUG: Monokiosk Get Started doesn't mention disabling signing checks

  Hi @malaire ,

  This information needs to be added also to https://monokiosk.com/get-started so that users going directly to monokiosk.com can see it.

  You are right, the Get started page on monokiosk.com, should refer to the Windows driver 8 /10 issue. Or link to http://developer.openmono.com/en/latest/getting-started/using_monokiosk.html

  Maybe @jpsecher, you can update the page?

  SONAR.Heuristic.150 is a heuristic detection for suspicious processes based on certain attributes.

  It must be a false positive. It is a heuristic - not an actual detection of a known threat. I suspect this heuristic will ignore us, after we release the signed installer.

  Trying to call periodically a function, mono keep flashing

  Hi all,

  First, @khchiang I hope my makefile has not left you completely bald headed :-)
  I have tried setting up the make system, such that changed dependencies are recompiled automatically. However I must admit that I have seen that changes to only header files will not trigger recompilation! The issue is on my todo list.

  Therefore: If changes are in only header files, with no changes to .cpp files - please do a make clean

  Flashing display

  This is a runtime exception / error. (@raute_at interpretation is indeed correct.) If the CPU encounters an invalid instruction (by executing data for example), or it tries to access protected memory, then a hardware exception is triggered. By default all exceptions are handled by a routine that flashes the display, and turns the User button into a software reset button. The code can be seen here.

  About mono_default_main.o

  This is just the default main() function, its content never changes. I guess compilers works in mysterious ways, since removing it has an effect.

  I hope this help to clarify the system. Please do not hesitate to ask, if you have something you been wondering about.

  Install of openmono on windows destroys path settings

  Sorry, but you were the first suspect after inspecting the path variable and finding only openmono items.
  It was probably the anaconda3 python distribution which emptied the path variable and openmono was the first installation after that.
  I remember that anaconda complaint about a long path entry some time before.
