It can be converted to RS232 level by MAX3232 chip. The communication data format is starting bit: 1 bit; Data bits: 8 bits; Parity bit: none. Stop bit: 1 bit.Note: All data are hexadecimal numbers. "Length" refers to the length + ope + parameter length + verification e. "Verification e" refers to the length + ope + parameter value (The verification e is one byte, only the lower 8 bits, and the excess is discarded). Specifies the file index playback command, which is 5 bytes in length.Playback CommandFunctionSent InstructionReturn eSpecify the file index playback command7E 05 A2 00 01 A8 EF→: 00 indicates that OK startsplaying.→: 01 indicates that the EMPdoes not have this file.Specify file name play7E 07 A3 54'T' 30('0') 30('0') 32('2) 90 EFFile index playback command in a specified folder (fixed foldername with 5 characters)7E 0A A4 'M'(4D)'U'(55) 'S'(53) 'I'(49) 'C'(43) 00 01 30 EF→: 00 indicates that OK startsplaying.→: 01 indicates that the EMPdoes not have this file.Command to play music file names in specified folders7E 0C A5 'M'(4D)'U'(55) 'S'(53) 'I'(49) 'C'(43) 'T'(54) '0'(30) '0'(30) '2'(32) 18 EFPause/Play Command7E 03 AA AD EF→00: Indicates that the OK command was successfully executed;→01: Indicates: FAIL commanderror;Next audio command7E 03 AC AF EF→00: Indicates that the OK command was successfully executed;→01: Indicates: FAIL commanderror;Previous audio command7E 03 AD B0 EF→00: Indicates that the OKcommand was successfullyexecuted;→01: Indicates: FAIL commanderror;Volume Control Command7E 04 AE 1F D1 EF→00: Indicates that the OK command was successfully executed.

During the recording process, when the storage is full, the recording will automatically end and return to 01 00.2. When deleting audio files, do not power off or unplug the memory. This will result in file corruption and even data corruption in the storage.3. The recording data is saved every 5 seconds. If the power is cut off midway, the recording data will be lost for 5 seconds.4. The command return e for starting and ending recording takes a time, which is related to the memory file and the read and write speed of the memory. It needs to wait for the return e to be received before execution is completed.5. The time interval shall not be less than 100ms when sending each command string.Application circuit diagramNote: QJ000-16S is a 3.3V IO system that can be directly connected to a 3.3V MCU.
