Can the same mbed be at the same time, slave and master(I2C)?
I am using just for testing both I2C Ports like this:
I2CSlave slave(p9, p10);
I2C i2c(p28, p27);
but it seems that the slave isnt acknowledging the master?

I get the same problem with the Nucleo152RE.
Looking at the HAL-Code in github shows me that they are doing nasty stuff with a global variable called I2cHandle. they do not update it correctly to allow more than one instance of i2c (slave or master).

Hello, I'm working on Nucleo F411RE. I have the same problem : I2C (master) alone talks without (too much) problems. I2CSlave alone talks, but this does not work :
I2C master(PIN1, PIN2); I2CSlave slave(PIN3, PIN4); while (tempo) slave.receive() /// Receives data ... master.write(something); /// Works correctly ... while(True) slave.receive() // Does not receive anymore
Has anyone a clue ? Thank you ...
Btw, I'm looking for a slave which would work by interrupts ... executing only on master's request ... Does not exist on MBed Nucleo ?
