Is it possible to test i2c without a slave device?

Hi,

I just wanted to ask how would you test the I2C protocol on the FRDM-kl25z without a slave device. Cos the slave device still hasn’t arrived yet for our project so I wanted to see if testing I2C is still possible. Thank you.

Ahoj,

I have not tested that but theoretically you can make a i2c loopback on one board with two i2c interfaces - one for Master and one for Slave.
Or if you have another board you can make a i2c slave from it as a simulator.
