    B4R Library BMP180 with ESP8266-01 support - Pressure and temperature

    This is a modified version of Erel's BMP180 library with support for ESP8266-01. The tiny ESP-01 board does support I2C but the SDA and SCL pins are different from the bigger boards' so the standard library does not work. You will not get a reading from the sensor. Instead, this library...

    Wish Possible to create real classes in B4R (and create instances of that class)?

    You can create class modules in B4R but they act as singletons - I can't define a class module say "MQTTBUNDLE" and then create instances of that class. I know the whole thing about low resources and all that but is this something that might be possible in the future? I'm using Types for this...
