i2c address 0x77 - Error and Safe Mode

[dmar29]

Hello, it´s my first time, that i write an issue on github. So sorry when i m doing it the wrong way. My BME680 comes with address 0x77. When i do so in the YAML-File, I got an Error-Message and the ESP goes in the Safe Mode. When i change the Config to 0x76 i have no Errors, but also no sensor-readings :-)

the normal config from esphome.io works with the address 0x77. so maybe it´s something in the bsec-framework? I just found a "hard entry" 0x76 in the init-File.

Sorry, that i made no Screenshots.

I'm not sure what "hard entry" you're referring to but if you can provide your config and log output then I may be able to help you.

I'm not sure what "hard entry" you're referring to but if you can provide your config and log output then I may be able to help you.

This part in your init-File:

    cv.Optional(CONF_STATE_SAVE_INTERVAL, default='6hours'): cv.positive_time_period_minutes,
}).extend(i2c.i2c_device_schema(0x76))

i copy all of your example code in my configuration and this is the log-file:

i think this is correct, because my sensor is at 0x77 and not 0x76. Here is the cofiguration with Adress 0x77:

The value you see in the init is just used to set the default: https://github.com/esphome/esphome/blob/5c86f332b269fd3e4bffcbdf3359a021419effdd/esphome/components/i2c/__init__.py#L37

Do you get any more of the decoded stack trace in your USB log or is that the end of the output?

It would also be interesting to know if your setup works if you temporarily disable your other i2c display device.

[dmar29]

it works without the display.

Interesting. I don't have an SSD1306 on hand to test with so I've ordered one. I've been meaning to have a play with the display stuff anyway so it's as good a device to start with as any! I'll report back once I have it and have had a chance to do some testing.

[caddyblack]

Just some information: I had similar event. After removing the display from the configuration it worked. I was assuming the display consumed too much processing time so the BME680 information was not processed correctly. I have no proof of it. I do have an MHZ-19 CO2 sensor in the same configuration as a reference. That combination is OK. All connected to a NodeMCU ESP8266.

[trvrnrth]

@caddyblack Thanks; that's useful to know. Your assumption sounds entirely plausible to me. It might be that the SSD1306 component needs to yield during it's write of display data.

[SenexCrenshaw]

Maybe @kbx81 can help. He helped with the latest code for the SSD1306

[trvrnrth]

@dmar29 Turns out it's not the display itself or the comms to it that are the issue here; it's loading in all the font glyphs that pushed things over the edge. I've made some improvements in #27 to reduce the RAM requirements of this component which has got things up and running for me on a test ESP8266 board.

You may also need to limit the glyphs loaded (see config) depending on what else you have loaded / if you add more fonts / images etc.

[trvrnrth]

@dmar29 I'd be grateful if you could try that branch out and let me know if that resolves things for you without any other changes :)
