Josicláudio: JVC Compulink, COMPU LINK, JVC, Tape Deck, Arduino, DCS Codes

Protocolo JVC COMPU LINK e Arduino

Quem tem um Tape Deck antigo com entrada COMPU LINK - 3, e não tem o amplificador com controle remoto, o mesmo pode ser controlado por outros equipamentos via cabo. Muitas vezes, obrigando à quem não tem os módulos restantes, pouco utilizarem o Tape Deck.

Exemplo de conexões

Ao procurar no GOOGLE, descobri, que existe um protocolo para envio de comandos via cabo, neste Site https://github.com/jcj83429/jvc_compulink .

Detalhe do protocolo, com 9 bits

Conforme o manual de serviço disponibilizado no Site, existem alguns comandos em Hexadecimal, que o usuário atestou na porta COMPU LINK.

DCS Codes(RM-S20) Remote Control

Agora, sei que dá para enviar códigos de controle neste terminal. Irei testar com um Arduino Mega.

Arduino Mega controlando Deck B

Conectando um Osciloscópio no terminal COMPU LINK e na terra do equipamento, ao pressionar play, observei parte do código que o equipamento enviou, provavelmente para ligar o resto do conjunto e pedir prioridade de execução.

Trecho do código enviado pelo Tape Deck

Agora, capturando o mesmo sinal na porta microfone do PC, rodando o programa Audacity.

Análise do sinal compulink com Audacity, sinal abaixo, reduzindo ganho do MIC

Agora como testar os Códigos DCS do manual:

- Realizar a conversão de Hex para Bin na calculadora do Windows.

Conversão do comando Play Hex/Bin

- Realizar alguns comandos (digitalWrite) no pino 13 do Arduino.

Pronto, o Tape Deck, respondeu perfeitamente!!!

No caso do programa acima:

- Inicia gravação no Deck b;

- Após 5S, realiza a pausa;

- Após 5S, Avança a fita;

- Após 5S, para;

- Após 5S, play;

- Após 5S, pausa;

- Após 5S, volta;

- Após 5S, para;

- Após 5S, troca o lado da fita;

Segue aplicação utilizada no Arduino Mega, para conversão e controle do Tape Deck JVC W218.

Pode ser modificado para várias aplicações, decodificações...

// Comandos play, avançar, retroceder, gravar, pausar, parar, trocar lado Deck B JVC W218
