Mac Lobdell / Mbed OS mbed-cloud-example_K64_K66

Simple Mbed Cloud Client application using features of K64 & K66

Connect to Mbed Cloud!

This example was customized a bit for FRDM-K66 and FRDM-K64F.

It depends on having an SD Card plugged in for storage of credentials. It could be changed later to use a SPI flash or other storage on a shield or wired in.

The app keeps track of how many times switch 2 (SW2) is pressed. The value can be retrieved via a GET request to Mbed Cloud.

Also, it will blink a pattern based on milisecond (ms) timing values that can be sent from Mbed Cloud. The pattern can be sent with a PUT request and the blinking sequence can be triggered by a POST request.
