WT5001 arduino
Guangzhou Waytroinc Electronics Co.,Ltd
WT5001 voice chip and module
Note: The instruction is to modify the playing mode when power on, when power down, the mode will return to
the mode which is configured in iSOUND.mp3 file. Using the instructions, it is proposal that MCU set the mode as
initializing the module to realize performing as setting each time.
4.2.12Instruction of copy the content from SD card to SPI FLASH
Start code
Length
Command
End code
7E 03 AA 00 7E
Note: It will return "AA" immediately after receive the instruction, while the indicator flashes, if copy
successfully it will return "AA 00", if not, it will return "AA 01"; the indicator stop flashing when the copy finished.
4.2.13Instruction of copy the content from U disk to SPI FLASH
Start code
Length
Command
End code
7E 03 AB 00 7E
Note: it will return "AB" immediately after receive the instruction, while the indicator flashes, if copy
successfully it will return "AB 00", if not, it will return "AB 01"; the indicator stop flashing when the copy finished.
4.2.14Instruction of insertion
Start code
Length Command High bit of songs Low bit of songs End code
7E 04 AC
00
01 7E
Note: When receive the instruction, the current song will pause, and then execute this command to playback
the specified song, when finish playing, it will play the original song which is pause. This instruction only can be
implemented in SPI- FLASH.
4.3Instructions of setting clock
4.3.1Set data information
Start code Length Opcode
7E 06 B1
Year 2bytesMonth(1byte)
2011
05
Day (1byte) End code
08 7E
Note: The year, month, day are hexadecimal code, such as the data of 2011 is 07 DB.
4.3.2Set time information
Start code Length Opcode Hour1byteMinute (1byte)
7E 05 B2 20
07
Note: The hour, minute, second are shown as hexadecimal code.
4.3.3Set waking up time information
Second(1byte)
08
End code
7E
Start code Length
Opcode
Hour 1byteMinute (1byte) Second (1byte) End code
7E 05 B3 0A
05
08
7E
Note: after executing this instruction, the clock of IC will record a time, when it’s time to the setting time,
DATA0 of IC will output one second pulse signal; after MCU of the controlling side detects the pulse signal from
INT, sent the inquiry instruction through the serial port to read the current time, then it will know to perform what
procedures this time.
4.3.4Set information of time period
Note: The first two bytes represent the starting time, the latter two represent the cut-off time.
Start code Length Opcode Hour 1byteMinute (1byte) Hour 1byteMinute(1byte) End code
7E
06 B4
06
05 06
08
Note: The former two bytes indicates start time,the latter bytes indicates the stop time
7E
If there is MCU, this function can be implemented through the microcontroller, so we do not consider to performing
any function.
4.3.5Clear the information of timing
Start code Length
7E 02
4.3.6Clear the information of time period
Opcode
B5
