Error compiling 'BME_280_BRZO_I2C_Test.ino' about bme280

[finitespace]

Alright, I had committed the wrong file last night.

With a fresh checkout as of 10/10/2017 10:26am MST:

-Modify BME280I2C_BRZO.cpp line 35 add: #define USING_BRZO 1
-Open example BME280_BRZO_I2C_Test
-Run "Verify".

I am getting a successful compile.

[finitespace]

Yes, I am aware of this bug. I am not sure why the compiler is not seeing the Brzo include define. Comment out/remove the #ifdef _BRZO_I2C_h at the top of the BME280I2C_BRZO.cpp and the #endif at the end. Tyler

[aderusha]

In file BME280I2C_BRZO.cpp I've removed the #ifdef _BRZO_I2C_h at line 36 and the matching #endif at line 88. No other changes from the test procedure outlined above. Compiling the example file BME_280_BRZO_I2C_Test.ino now returns the following errors:

Pull down the latest version and try again. I wasn't getting the same compile errors as you, but I did fix some things.

I was getting a bug with :
'#define SDA_PIN = D2
#define SCL_PIN = D1'
it wasn't liking D1 & D2. I don't have time to debug it now, but I will look at it tonight. You might be able to get it working now.

[aderusha]

Still no go. Test procedure is now:

• Unzip arduino-1.8.4 to C:\arduino
• Create C:\arduino\portable
• Add ESP8266 board manager URL, install ESP8266 board support, and select NodeMCU 1.0 (ESP-12E Module) from Board Manager
• Install library Brzo I2C Version 1.31 from Library Manager
• Install library BME280 from ZIP file downloaded ~ 11:00am GMT 2017-10-10
• Open example BME280_BRZO_I2C_Test
• Run "Verify" and the following error occurs:

Arduino: 1.8.4 (Windows 10), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, 115200, 4M (3M SPIFFS)"

Confirmed working! The example file now compiles with the instructions you've provided and I am now able to successfully read data from a test BME280 device connected to D1/D2 on a Wemos D1 mini. Thank you so much for your work on this and the crazy-fast turnaround on squashing bugs, I really appreciate it!
