  1. The I2C Monitor telos Connii MM 2.0 does only recognize regular I2C transfers, no I2C error conditions etc. Thus it is not well-suited for finding problems on I2C communication level. telos Connii MM 2.0 may occasionally stretch SCL, i.e. the SCL line is held low for a short period of time. That may lead to problems with master or slave devices that do not support SCL stretching (like some I2C single master implementations).

    telos Tracii XL 2.0 offers a more sophisticated I2C Monitor, which includes time stamps for every byte and error recognition.
