jewelbots / arduino-library Goto Github PK

Given the following program

#include <Arduino.h>

LED led;
bool ran;

void setup() {
}

void loop() {
  if (!ran) {
    led.on(1, "blue", 100000);
    ran = true;    
  }
}

The blue light will blip and then instantly goes dark, there is no delay.

From the forums, there is a request for being able to call the buzzer with a specified buzz duration.

From this thread: http://alpha.jewelbots.com/t/finer-control-of-buzzer/254

When I updated Arduino IDE to this: https://jewelbots.github.io/arduino-library/package_jwb_staging_index.json the Jewelbots board entry disappeared, so I opened it in a browser and discovered that it's a 404

in LED.h, the timing parameters for flash_single and flash_all are incorrectly named microseconds. They are actually expecting milliseconds.

compare LED.h to LED.cpp.

it's a minor issue, but was a little surprising when my daughter and i stumbled across it.

Given the following code

#include <Arduino.h>

Animation animation;

void setup() {
  animation.rainbows();
}

The setup() code does not appear to run

Before I spend a significant amount of time deep diving through the repository, is there anything known reason or possible explanation for the present size of the repository? If so, are there any cursory thoughts on how to address?

When a sketch is uploaded, an error message occurs that is not an actual error. This is confusing for the user. The message is

Failed to execute script __main__

Explanation from @davison-sm here:

The tool is here: https://github.com/NordicSemiconductor/pc-nrfutil

There are multiple branches with different versions. Master is the updated tool for SDK 12 and will not work for us as we haven't upgraded to 12 yet. The branch that will work for us is "0_5_2".

The code works fine when installed normally in the system using "python setup.py install". This nrfutil tool runs perfectly and doesn't give the error message. But it is installed on the system using links, so the executable can't be distributed on our github.

The standard method of making a distributable executable would be "pyinstaller --onefile setup.py". The installer builds correctly, but gives an error about a broken import module command when it is run.

To make the executable that we are using now, run pyinstaller on the main.py file in the nordicsemi folder. This executable runs but has the annoying error message.

I was working on a project fully expecting to be able to call millis, a function that

the number of milliseconds since the Arduino board began running the current program.

Unfortunately the code does not compile because

error: 'millis' was not declared in this scope

It would be great if the millis function would be provided as a function.

Is there any document that provides developer guidance for this library? Specifically, how do I use the repo master (or feature branch) as the source in Arduino IDE? When working with other Arduino libraries, that are board specific, the board definitions that are installed via Tools -> Board -> Boards Manager are decoupled from the libraries installed via Sketch -> Include Library -> Manage Libraries. That enables placing a development repo in the ~/Documents/Arduino/libraries/ directory

I think I tried to run before I could walk (I got excited hehe, my fault) - but I connected via BLE to the Jewelbot bracelet (not the dev board) and I didn't get any services or characteristics back (but did get a list of service UUIDs ['180d', '1814']). Again I'm jumping ahead, but are these set up manually via the sketch file uploaded to the device? If so, I can dig around and have a go at that.

In the meantime, I'll try to be more helpful by uploading the example sketch on both the dev board and the bracelet 😁

Hello! I'm running into an error attempting to update my Jewelbot's firmware.

Sure enough, the file doesn't exist:

Please let me know if I can answer any questions or be of any further help.

The new colors are great! The breathing animation only contains the old ones, the animations code needs to be updated to make sure users can use breathe with the new colors.

This code exists in the animations.cpp and animations.h files.

Was interested in forking the repo and playing around. On setup, noticed the URL for the staging pkg JSON is a 404.

https://jewelbots.github.io/arduino-library/package_jwb_staging_index.json

also tried a few guesses like

https://jewelbots.github.io/arduino-library/package_jewelbots_staging_index.json
https://jewelbots.github.io/arduino-library/package_jewelbots_staging.json

all 404's

The friendship coding board has a random number function that is not also on this board. It's called get_rand_int. It would be great to have it on this board as well!

MacBook Pro (Retina, 15-inch, Mid 2015)
macOS Sierra v10.12.5

1. open a sketch, does not matter if its new file or user made sketch
2. plug in your JB and try to upload your code WITHOUT putting the JB into the upload mode
   there will be an error
3. click the verify button to verify your code(I had no errors what so ever when checking my sketch)
4. put the JB into uploading mode
5. try to upload your sketch
   it gives me the same error of step number 2. The JB does not exit out of uploading mode and no matter what I seem to do either on the JB or on the Arduino, The JB does not seem to react either to the sketch that is on it or the new sketch I tried uploading, in fact it seems to do nothing.

The only solution that seems to work is the 2 min timeout of the uploading mode(I have not been able to test the reset button because I don’t have anything small enough around me that will fit)

Please try this yourself and feel free to try to change it up a little bit to see if there are one than one way of doing this and if this is only happens on mac or it happens on macs, windows and linux

The "hello world" sketch on the main readme fails to compile with the error "'class LED' has no member named 'on'". The example at https://github.com/Jewelbots/arduino-library/blob/master/jewelbots_nRF51822_board_v100/Examples/JWB_blank/JWB_blank.ino does compile, so either that should get moved up to the main page, or the existing example should be updated to reference turn_on_all or some other method that exists.

Not here!

I'm filing this separately because I'm not sure if it's a dupe of #1. If it is, then just close this.

Failed to upgrade target. Error is: No data received on serial port. Not able to proceed.

Possible causes:

• bootloader, SoftDevice or application on target does not match the requirements in the DFU package.
• baud rate or flow control is not the same as in the target bootloader.
  Failed to execute script main
• target is not in DFU mode. If using the SDK examples, press Button 4 and RESET and release both to enter DFU mode.

I tried this:

• target is not in DFU mode. If using the SDK examples, press Button 4 and RESET and release both to enter DFU mode.

No luck!
