This Demo uses the Tuya smart cloud platform, Tuya smart APP, BH1750and IoTOS Embedded MCU SDK to realize a illuminance acquisition.
The implemented features include:
- Illuminance Acquisition
- Download Tuya IoTOS Embeded Code
- Execute the Project.uvprojx file
- Click Compile in the software and complete the download

Entry file：main.c
Important functions：main()
- Initialize and configure MCU USART,IIC,BH1750sensor, etc. All events are polled and judged in while(1)。
- DP point processing: mcu_dp_value_update()
| function name | unsigned char mcu_dp_value_update(unsigned char dpid,unsigned long value) |
|---|---|
| dpid | DP ID number |
| value | DP data |
| Return | SUCCESS: Success ERROR: Failure |
