Serial port to send the command byte:
( 1 ), serial communications parameters (baud default value 115200 bps , can be set by software)
Baud Rate: 9600 bps parity bit: N Data bits: 8 Stop bits: 1
Baud rate: 115200 bps parity bit: N Data bits: 8 Stop bits: 1
( 2 ), the module input commands sent by an external controller to the GY-MCU90615 module (hex)
1 , header: 0xA5
Instruction format: header + command + checksum (8bit) (such as automatic read temperature command = 0xA5 + 0x45 + 0xEA )
2 , the command instruction:
Continuous output instruction:
0xA5 + 0x45 + 0xEA ---------------- temperature data (module returns data type 0x45 )
Query output instructions:
0xA5 + 0x15 + 0xBA --------------- temperature data (module returns data type 0x45 )
Configuration instructions : ( become effective after power reboot )
Baud rate configurations:
0xA5 + 0xAE + 0x53 --------------- 9600
0xAF + 0x54 0xA5 + --------------- 115200 (default)
Is powered automatically send temperature data configuration:
0xA5 + 0x51 + 0xF6 --------------- output temperature data automatically after power
0xA5 + 0x52 + 0xF7 --------------- not automatically after power output temperature data ( default )
Serial port to receive:
( 1 ), serial communications parameters (baud default value 115200 bps , can be set by software)
Baud Rate: 9600 bps parity bit: N Data bits: 8 Stop bits: 1
Baud rate: 115200 bps parity bit: N Data bits: 8 Stop bits: 1
( 2 ), the module output format, each frame contains 9 bytes (hex):
① .Byte0: 0x5A Preamble Flags
② .Byte1: 0x5A Preamble Flags
③ .Byte2: 0x45 The frame data types (0x45 : temperature data)
④ .Byte3: 0x04 amount of data (hereinafter 4 data 2 groups for example)
⑤ .Byte4: 0x00 ~ 0xFF Data 1 high 8 bits
⑥ .Byte5: 0x00 ~ 0xFF Data 1 lower 8 bits
⑦ .Byte6: 0x00 ~ 0xFF Data 2 high 8 bits
⑧ .Byte7: 0x00 ~ 0xFF Data 2 lower 8 bits
⑨ .Byte8: 0x00 ~ 0xFF checksum (data accumulation and front, leaving only the lower 8 bits)
( 3 ), data calculation method
Temperature calculation method :
Temperature = high 8 bits << 8 | lower 8 bits (the result is multiplied by the actual angle 100 )
Example: Send command: A5 45 EA, received a data:
<5A- 5A- 45- 04- 0C- 78- 0D- 19- A7>
Represent TO (signed 16bit , represents the target temperature): TO = 0x0C78 / 100 = 31.92 ° C
Represents TA (signed 16bit , represents the ambient temperature): TO = 0x0D19 / 100 = 33.53 ° C
Instructions:
The module for the serial output data, the user is connected via the serial port to send output command, for example 0xA5 + 0x45 + 0xEA to the module, the module output temperature data continuously; To query output can be sent 0xA5 + 0x15 + 0xBA to the module, each send once, the module will return once the temperature data, queries should be lower than the frequency of 10hz , For higher than 10hz use continuous output mode, ie send 0xA5 + 0x45 + 0xEA instruction;
Note: Module I / O is TTL level, you can, with direct serial connection with the microcontroller directly PL2303, CH340, FT232 connected to other chips, but not directly connected to the computer nine-pin serial port.
