• BangleJS 2 Emulator slows down when writing an app

  in Bangle.js • 1 week, 3 days

  

  There is also https://github.com/espruino/BangleApps/blob/master/modules/graphics_utils.js. Maybe you can use that or modify it to have the features you need.
  As for "local" development a relatively simple way is to check out the BangleApps and EspruinoWebIDE repos with their submodules and start a webserver in the parent folder of those. I use python3 -m http.server 4001 --bind 127.0.0.1. You can then access app loader and IDE at localhost:4001/BangleApps and localhost:4001/EspruinoWebIDE. Any webserver should work for that. It should be on the same machine as you work on since hosting it at another IP means you need to setup certificates for web bluetooth to work. There is an exception in the security rules for localhost.

• Increasing menu item thickness in custom app?

  in Bangle.js • 2 weeks, 3 days

  

  You can override the E.showMenu to change the appearance of all menus using that.
  There are some apps already existing like menuwheel or touchmenu. Maybe one of those is close enough or you can use them as a template for creating your own.

• [Bangle.js 2] modification: add buzzer, bigger battery, more switches, minus HRM

  in Bangle.js • 3 weeks, 3 days

  

  That's awesome! Turning the motor on its side and fixing it to the case directly to amplify the buzz is something I could imagine to do in my next version as well since it is well cushioned/dampened when on the battery.

• Change forum to GitHub Discussions?

  in General • 3 weeks, 4 days

  

  GitHub Discussions is fine for me. Is there a sensible way to migrate away from GitHub Discussions if the need arises?

  Nice, I did not know that analogWrite could do PWM with custom frequency.

  How do you drive the piezo in software? Just triggering the output pin in a loop?

  Your wishes for a new case seem similar to mine, maybe you can find some useful information in my thread trying to design a custom case. https://forum.espruino.com/conversations/388860/

• Banglejs 1 LCD screen glitch

  If you can find some sign of water ingress and drying it out is not enough maybe rinsing in distilled water to remove minerals is worth a try.

• Gadgetbridge shows heart-rate and activity when not wearing the watch

  in Bangle.js • 2 months

  

  You could try Sleep as Android https://sleep.urbandroid.org/ in combination with https://banglejs.com/apps/?id=accelsender
  I have not tried those but I saw Gadgetbridge supposedly gaining support a few months ago.

  Actually not that hard. It seems the optically clear glue between glass and digitiser can be broken down with isopropanol. I practically soaked the whole assembly and pulled a thin nylon string between glass and digitiser to separate them. But it destroys the other glues as well, so just removing the glass will not work, the whole thing came apart, including backlight distribution plate. I do not know if it can be put together well enough to use. This display already had a partly malfunctioning digitiser, so I took it apart just to see if it was possible. Touch seems the same as before but that is a sample size of one.

  I ran into a problem with the buttons, there seems to be a limit to used GPIOs at the same time or something. Using both works fine if the HRM is off. Otherwise I get WARNING: No free GPIOTE for watch for the second one. Does this need a firmware change or is there another workaround?
