Morse code decoding encoder CW code audio serial port coded up to 54

Morse code decoding and encoding module

Overview:

 MC310It is a Morse code decoding and encoding module.

Code sending process:Is input through the serial portASCIIAfter the code is received by the module, it is converted into Morse code, and then converted into an audio signal.3.5MMEmitted by the audio interface.

Code receiving process:Is used3.5MMThe audio interface converts the received audio signal into Morse code, and then toASCIIThe code is sent through the serial port.

 This module can use audio cable to connect input and output together, send and receive data at the same time, the module can receive serial port30Data waiting to be sent.

Applications:

● Morse code learning;

● Morse code decoding;

● Morse code encoding;

Technical Data Sheet:

Features: (1) Receive and send data through the serial port.
(2) Input and output can be connected together with audio cable, and data can be sent and received at the same time.
(3) The module can receive 30 data from the serial port at a time and wait for transmission.
(4) The received data is sent out through the serial port immediately.

Drive mode: serial port communication format: baud rate 9600, no parity, 8-bit data, 1-bit stop

Module interface:
  
(1) Communication interface P2:
5V: Positive power connector (5V).
GND: power ground interface.
RXD: the receiving end of the module; connected to the TXD of the microcontroller (MCU)
TXD: the transmitting end of the module; connected to the MCU (MCU) receiving end RXD

(2) Signal input interface P4: 3.5MM audio input interface (input 700Hz ~ 3000Hz).

(3) Signal output interface P5: 3.5MM audio output interface (output 1000Hz audio signal).

Adjust input through RW1 potentiometer (range 700Hz ~ 3000Hz).

Module and wiring block diagram:

 Note: Please do not connect the circuit module directly to the serial port of the computer.RS232turnTTLModule) converts signals intoTTLOnly level signals can be connected to the circuit module, otherwise the module will be damaged. (RS232The signal is negative15Fu Zhizheng15Volt, TTL232The signal is0Fu Zhizheng5Volts)

Morse code

Introduction: The telegraph was first developed by American Morse in1844Invented in 2000, it is also called Morse code.

It consists of two basic signals and different intervals: short dot signals"*",read"of"(Di); Keep one

Long signal"-",read"answer"(Da).

Interval time: drops,1t;answer, 3tTicking room, 1t; Between letters, 3t; Between words, 5t(Customize a certain unit timet).

Note:*Indicates a short signal,-Means long signal
