Demo entry

Entry file：main.c

Important functions：main()

• Initialize and configure MCU USART，TIME，SPI，LORA，LCD, etc. All events are polled and judged in while(1)。

DataPoint related

• 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

• MCU gets the dp value of the bool type:mcu_get_dp_download_bool()

function name	unsigned char mcu_get_dp_download_bool(const unsigned char value[],unsigned short len)
value[]	DP data buffer address
len	DP data length
Return	The current values of dp
