Help - Communication I2c - Stm32 / Arduino UNO

Post by weslleymata » Mon May 29, 2017 12:40 pm

Hello everyone,

I'm looking for an example of "I2C" communication between the stm32f103 "blue pill" and an "arduino UNO" but can not find anywhere,

I searched several sites and could not find any information

Why don't you just try it and tell us where you get stuck?
There is plenty of documentation on i2c for both. maybe not on using them together, but worst case you'll need a logic level shifter.

"I2C" communication between the stm32f103
the F1, together with other ST products (like STM8s), has lots of code that are not compliant with regard to the datasheet (on EV6).

So be careful trying to use such code pieces -> even ST's own standard peripheral library doesn't follow its own datasheet on that.
