I found your library from this (https://www.best-microcontroller-projects.com/bmp280.html) article and have found it to be perfect for my needs. However, it did not work on my chosen micro controller as-is. Some of the dependencies must be different when using ESP8266 based micro controllers. For my use, I have made the following changes that seem to be working for me. Since these changes are to one of you base classes, I don't know if there are any ramifications that should be noted.

`WirePlus::WirePlus()
{
Wire.begin(); // I2C as Master

#ifdef ESP8266
// DEC - TODO: I've added this as PORTC, TWBR were undefined
// when using on ESP8266 board. Arduino.cc pages state
// that PORTC has to do with analog pins. Why would this
// digital port library need to change these? Need to
// figure this out.
Wire.setClock(400000L);
#else
bitSet(PORTC, 4); // deactivate internal pull-ups for twi
bitSet(PORTC, 5); // as per note from atmega8 manual pg167
// switch to 400KHz I2C - eheheh
TWBR = ((F_CPU / 400000L) - 16) / 2; // see twi_init in Wire/utility/twi.c
#endif // ESP8266

};
`

In the file "i2c.h" in the function "read" is a Wire.endTransmission at the end, after a Wire.requestFrom.
That last Wire.endTransmission can be deleted, since Wire.requestFrom should not be followed by a Wire.endTransmission.

The Wire.beginTransmission and Wire.endTransmission are only used when writing data.

Hello,

Congratulations for your very useful library! I would like to ask if you are planning to add support for the BME280 sensor?

Thanks,

Hi, great library! Thanks!

I just ran your BMP 280 example code. Do you plan to add support for reading the humidity?
