Why can't I add the ArduinoGraphics library in Arduino App Lab?

Official Hardware UNO Family UNO Q

i flipped the switch. first, arduino logo is booting up. then hearth. and? no program is running. display is blank.

42

is it possible to flip text vertically? then 4 digits would fit. in Y direction. And is RTC library for uno Q avalialble? the same one as for UNO R4 - with periodic RTC interrupts from 1/128 to 2 seconds? so the range of my clock can be expanded to 272 years, until 2 second counter rolls over at 32 bits. like in UNO R4?

Please verify that the App was correctly configured as the default:

  1. Start Arduino App Lab.
  2. Connect Arduino App Lab to your UNO Q board.
  3. Select "My Apps" from the bar on the left hand side of the Arduino App Lab window.
    The "My Apps" view will open.

Now check to see if there is a "DEFAULT" label on the App. For example, here you can see that my App named "FooApp" is configured as the default App;

@ptillish - Side note on setting the default "App"
When you do this, if you then later go and reprogram the Arduino sketch part
using Arduino IDE, it runs fine with the new app, however, if you then turn the
Q off and later back on.

The Q will startup with the Arduino Sketch first and then after a bit of time, it will
then restart your selected app. (or in some cases with my setup where
I programmed the Q MCU with a different version of Zephyr, it potentially
crashes...

Not sure what the right behavior should be:
Should uploading sketch by Arduino IDE, uncheck the default?
Should it replace only the Sketch portion of the checked app?
or what it is doing is correct?
Or maybe there should be some way to specify?

after one more time.. it started as inteded.

If you find the App is starting only intermittently, it might be caused by a power supply problem.

The UNO Q is a very powerful board, and thus has more demanding power requirements than the typical Arduino board. Even when you determine that a power supply is sufficient for the typical current draw of the device, it will need to also be able to accommodate short periods of higher current draw. If the power supply can't do that, then you might find that the device does not work reliably. In the case of the increased current draw that occurs on start up, if the power supply is not sufficient then the board might get stuck in a non-functional state where it is not able to start the App.

If you are powering the UNO Q via a USB cable, make sure to use a good quality cable. Any cable from an established brand should be sufficient. Be careful about the sourcing of the cable. There are a lot of counterfeits out there, meaning you might think you are using a good quality name brand cable when what you have is actually low quality. Additionally, online marketplace listings are often worded in a manner that can lead you to believe you will receive a name brand cable when you are actually purchasing a generic cable with no guarantee of quality. I am currently using an Amazon Basics brand cable and haven't encountered the problems I did experience periodically while using a cheap generic cable.

I also found that you need 3A thick cable, preferably USB-C on both ends. Otherwise board starts 50/50 from powerbank
