Compilation error during build on latest (beta/dev) esphome

[T-REX-XP]

Hello. I have got a problem with compilation firmware for wemos d1 board, when your module is imported. At first I have fixed all includes.But still have another errors. Could you please fix this module for using with latest version of esphome.

Thanks.

Could you copy/paste the errors here? I'm thinking about creating a pull req to esphome from this repo. I'll need some time to polish the code. Link esphome/feature-requests#14

here is the compilation issue:

Apparently, now you need to use

namespace esphome {
}

instead

[T-REX-XP]

Is it resolve compilation issue?

[saikek]

nope... I've tried few tweaks, but my C++ level is not enough to resolve this issue. Also I need some animations, so most likely at this moment I would grab pieces of code from different places (NTP time sync, MAX7129 display, BMP280 sensor).

https://github.com/MKme/Wemos-D1-Subscriber-Counter-MAX7219-LED-Matrix/blob/master/D1MiniSubscriberCounterMAX2719/D1MiniSubscriberCounterMAX2719.ino

looks promising for what I want.

[saikek]

I've ended up using https://github.com/Qrome/marquee-scroller for my specific task if anyone is looking for a library / binary.

Has anyone solved the compilation errors that come up during the build? Also building for ESP8266, Nodemcu V3. As above getting the errors on lines: 'ESPHOME_NAMESPACE_BEGIN' 'ESPHOME_NAMESPACE_END' As above I have tried tweaking and using 'namespace esphome {}' but had no joy, my C++ knowledge is definitely not up to scratch. It would be great to see this as a component in ESPHome eventually!

My pull request https://github.com/ASMfreaK/esphome_max7219/pull/4 fixes all compilation issues and works with the scrolling vertical lines example. I don't think the functions to print text or the time are currently working.
