On the NUCLEO-F401 are the I2C and other serial ports implemented? I see reference to I2C0 in the BNO055 example but what pins are these assigned to? I checked the pinmaps but only NodeMCU have these on the pinmap image. Can I see the code for the BNO055 example to use when writing my own drivers?
OK, I found in Zerynth Studio when you press the pinmap button, and select Peripherals where it says Pinmap Select it shows the I2C, SPI, Serial and other peripherals.
