does I2C support over clocking ??

I'm trying to connect a thermal sensor onto my crazyflie 2.0 but not sure if it supports any over clocking. Also I'd like to know how exactly do I read data from the i2c bus on my comp. I'm a newbie and not very proficient with this just yet. Any help?? Can I get it in the cfclient ? Or read it via some program like teraterm ?

Why do you need temp, are you going to fly into a volcano?

The pressure sensor actually already contain a temp sensor. The problem is that the board temperature rises quite a bit when it is on. One solution is to find out how much it rises and calibrate for that or to make the board use less power (less heat) by setting the STM32 CPU frequency lower (requires some firmware changes and adaptations)

The temp data you can plot in the cfclient by making a new log configuration with baro->temp.

Hahaha....not fly into a volcano but my research is in swarm and formation control. I'm trying to get them to fly up transmission lines and other structures looking for electrical faults etc.

I'm looking to identify external temperatures with a non contact thermal sensor.
