(Basic) support for Flow3r Badge (c3camp 2023)

[simonmicro]

→ https://flow3r.garden/

Well, this not only adds the (basic) hardware support, but also (consequently) enhances and migrates the platform-abstraction layer to accommodate for the new hardware...

Checklist / ToDo

• Compile
• First boot
• Get display working (-> datasheet)
• WiFi
• Buttons (for now, just the standard ones (up, down, select))
• Add accelerometer support (BMI270)
• Add pressure support (BMP581)
  • ⚠️ This sensor is attached to the auxiliary I2C interface of the BMI270 - this significantly changes how to interact with that sensor, so direct I2C interface code cannot be used!
• LEDs? (better if devs add it when needed; for now too unique on this platform; hint: FastLED)
• Capacitive Touch? (better if devs add it when needed; for now too unique on this platform; hint: use the schematics and implement SPI driver for the GPIO extenders)
• Get serial working properly over the jtag-serial interface (because the usb-c sidechannel requires a special cable)

Known Bugs

• If the badge enters sleep, you have to reset it → sleep is blocked for now via OSW_PLATFORM_BLOCK_SLEEP
  • ...currently the accelerometer-interrupt is not working, so the badge won't wake up upon tap
  • ...buttons and interrupts... Maybe we can also use them?

Fails for me with:

I did update the submodules

[schneider42]

I tried 72aa546 (before BIM270 support gets introduced) and that builds and runs in principle:

I was able to connect to the AP it opened up, but couldn't connect to the IP displayed using various ports. I'm a first time user and haven't read the docs though :)

Connecting it to my home WiFi and showing the current time works (modulo me not understanding the timezone field)

Heyho, nice to hear!

So, regarding the missing header: Did you ensure to update and initialize the submodules? So, did you run git submodule sync; git submodule update --init? Otherwise, maybe I've missed adding the repo.

Regarding the web interface problems: Take a look into the platformio.ini header and remove the OSW_FEATURE_WIFI_APST feature flag (allow simultaneous station and client mode). I assume this is causing the ESP-IDF framework to mess up the connection. Now the UI should load... Right?

Hey, I just pushed 71b8e18 - hopefully this fixes the broken submodule...

(inside the debug-app or inside the web-ui)?
