Cell phone accessory identification algorithm by generating and measuring a voltage pulse through a pin interface |
摘要 |
In some embodiments, a method is provided for identifying a communication interface of an electronic unit attached to a connector of an electronic device. A voltage pulse is generated in the device on a pin of the connector. The voltage on the pin is measured, as it is affected by a load in the unit. The measured voltage is compared with predetermined voltage criteria. Communication interface identification is performed on the unit dependent on the comparison.
