Tuya IoTOS Embedded Demo WiFi & BLE Rotary Encoder

English | 中文

Introduction

This demo is based on Tuya IoT Platform, Tuya Smart APP, IoTOS Embeded WiFi&Ble SDK, using Tuya WiFi/WiFi+Ble series modules quickly build a rotary encoder detection application . When the rotary encoder rotates clockwise, the gear increases by 1, and the lights turn on in sequence; when the rotary encoder rotates counterclockwise, the gear decreases by 1, and the lights turn off in turn.

Quick start

Compile & Burn

• After creating a product on Tuya IoT Platform, download the SDK from the development materials of hardware development.

• Download the demo to the demos directory of the SDK:

  $ cd demos
  $ git clone https://github.com/Tuya-Community/tuya-iotos-embeded-demo-wifi-ble-rotary-encoder.git

  (Note: The build.sh in the Demo is only required to be used in the SDK below version 2.0.3.)

• Execute the following command in the SDK root directory to start compiling:

  sh build_app.sh demos/tuya_demo_rotary_encoder tuya_demo_rotary_encoder 1.0.0

• Firmware burn-in license information please refer to: General Wi-Fi SDK programming authorization instructions

Entry to application

Entry file: /demos/src/tuya_device.c

Important function：device_init()

• Call the tuya_iot_wf_soc_dev_init_param() interface to initialize the SDK, configure the working mode, network distribution mode, and register various callback functions and save the firmware key and PID.
• Call the tuya_iot_reg_get_wf_nw_stat_cb() interface to register the device network status callback function.

Data point (DP)

• Report dp point interface: dev_report_dp_json_async()

Function name	OPERATE_RET dev_report_dp_json_async(IN CONST CHAR_T *dev_id,IN CONST TY_OBJ_DP_S *dp_data,IN CONST UINT_T cnt)
devid	device id (if gateway, MCU, SOC class device then devid = NULL; if sub-device, then devid = sub-device_id)
dp_data	dp structure array name
cnt	Number of elements of the dp structure array
Return	OPRT_OK: Success Other: Failure
