A code sample showing the use of the asynchronous Serial APIs.

Dependencies:   mbed

Beware: this example is only compatible with boards supporting the asynchronous APIs!

Information

All examples in this repo are considered EXPERIMENTAL QUALITY, meaning this code has been created as one-off proof-of-concept and is suitable as a demonstration for experimental purposes only. This code will not be regularly maintained by Silicon Labs and there is no guarantee that these projects will work across all environments, SDK versions and hardware.
