How to use Watchy with Platformio

[silmaril42]

I don't really understand the folder structure of this project.

The example watch faces obviously contain ino files meant for Arduino IDE - but you can't do much here. I don't even see an option to change the city.

In the src folder it's all cpp and h files that look more like something I would like to meddle with :smiley: And I even found the config.h where I can set all the user settings.

Has anyone got this to work in Platformio yet? I seem to be able to install the Watchy library, but there is no board type to select for it.

I'd really love to use Platformio for programming this gadget and I'd appreciate any help someone with more knowledge of this could provide.

I converted the Watchy project to an PlatformIO project. Here is the .zip file of it: WatchyPlatformIO.zip I manually included the Watchy library from source. If you want to use the precompiled like in the Arduino IDE just use this in the platformio.ino:

lib_deps = 
	sqfmi/Watchy @ ^1.2.6
        adafruit/Adafruit BusIO@^1.7.5

UPDATE:

Thanks to @Charles-Haynes (from here) I removed board_build.flash_mode = qio as it is the recommended way to do so. I also updated some dependencies. Here is the updated projected: WatchyPlatformIO.zip

You may also need to include this line in your platformio.ini:

board_build.partitions = min_spiffs.csv

For the larger demos, the compiled size will be too large otherwise.

Great, thank you very much!

Now I am really looking forward to the weekend, when I hope to find some time to meddle with this. :+1:

How do I set the city/temp units? This was my first question as well. I submitted PR https://github.com/sqfmi/Watchy/pull/62 as a possible solution.

Obviously I know that I didn't purchase a fitbit here, as well the sqfmi developers have been focusing on the hardware production and not the software, but a little bit of instructions or comments in the examples would go a long way. Even just as a hint as to where to go next.

@adamm If you are on Windows go to C:\Users\[your username]\Documents\Arduino\libraries\Watchy\src in there is a file called config.h. There are following lines:

27 //weather api
28 #define CITY_NAME "NEW+YORK" //if your city name has a space, replace with '+'
29 #define COUNTRY_CODE "US"
30 #define OPENWEATHERMAP_APIKEY "f058fe1cad2afe8e2ddc5d063a64cecb" //use your own API key :)
31 #define OPENWEATHERMAP_URL "http://api.openweathermap.org/data/2.5/weather?q="
32 #define TEMP_UNIT "metric" //use "imperial" for Fahrenheit"
33 #define WEATHER_UPDATE_INTERVAL 30 //minutes

In those lines you can set your location and temp units.

be a little careful. That platformio project specifies board_build.flash_mode = qio but the board description for pico32 says you should use board_build.flash_mode = dio I just got bitten by that yesterday. Worked fine for quite a while then mysteriously stopped working till I changed to dio mode (by deleting the line entirely and relying on the default.)

[etwasmitbaum]

you should use board_build.flash_mode = dio

Thanks for info. Wasn't aware of that, I just copy pasted what I used in Arduino.

I updated my comment above with the changed flash mode.

[cehbz]

Actually, dio is the default for board = pico32 so you should probably just delete the board_build.flash_mode = ... line entirely. Most boards will specify their preferred flash mode.

BTW - thanks for posting that zip, I used it to get started and it was very helpful. I only found the qio/dio problem because after many days of working, suddenly uploads completed but failed to boot.

[etwasmitbaum]

Just updated my comment from above again and removed the line.

I am glad to I could help you with my zip :)

It would be really good if somebody could supply a PR that gives a working platformio setup for the examples. I think you need:

• Move source files to src directory. This seems to be required for platformio. Hopefully it won't break arduino builds(?).
• platformio.ini file from above zip file.
• Fix the path to Watchy source. Relative paths seem to be OK, so ../../.. is fine.

Seems to work for me. So far.

Yeah, I've been having a lot of issues getting this working. This is the first time I've used platformIO so I'm a bit unfamiliar with the configuration process as is though.

I'm trying to get the updated example from above to work but get this error:

My platform.ini is as follows:

[env:pico32]
platform = espressif32
board = pico32
framework = arduino
monitor_speed = 921600
board_build.f_cpu = 240000000L
board_build.f_flash = 80000000L
build_flags = -DCORE_DEBUG_LEVEL=0
board_build.partitions = min_spiffs.csv

	arduino-libraries/Arduino_JSON@^0.1.0

	zinggjm/[email protected]
	https://github.com/tzapu/WiFiManager.git
	adafruit/Adafruit BusIO@^1.8.2
	sqfmi/Watchy@^1.4.6

So basically I'm importing sqfmi/Watchy@^1.4.6 instead of the included watchy lib. But that one also didn't work which is why I'm trying this instead.

Is there maybe an updated working project using PlatformIO?

Thanks!

[sommerper]

Never mind. I managed to fix it by deleting everything in the src folder and copying Watchy/.pio/libdeps/pico32/Watchy/examples/WatchFaces/7_SEG to src. Then renamed the .ino to main.cpp.

After pressing upload the project compiles and is uploaded to the watch.

Hello @joeleonjr, thank you for making me aware! The API, key you are referring to, is the default API key from the Watchy source code here. So it already was and still is publicly available. But thank you again for making aware.
