Tomo Yamanaka / Mbed OS GR-LYCHEE_mbed-os-client-ZXingSample

Mbed Client sample for GR-LYCHEE where ZXing is incorporated.

Dependencies:   DisplayApp AsciiFont

Fork of GR-PEACH_mbed-os-client-ZXingSample by Renesas

Overview

This sample program shows how to use mbed Client together with ZXing which is an open-source, multi-format 1D/2D barcode image processing library. For more info on ZXing, please refer to https://github.com/zxing/zxing.

Application resources

This example exposes four resources listed below:

1. 3202/0/5700. Decode result of barcode data input from camera (GET).
2. 3201/0/5850. Blink function, blinks LED when executed (POST).
3. 3201/0/5853. Blink pattern, used by the blink function to determine how to blink. In the format of 1000:500:1000:500:1000:500 (PUT).
4. 3201/0/5855. Blink color, used by the blink function. Any of green, yellow, orange and red is acceptable (PUT).
