Olá Luan, tudo bem? Estou tentando desenvolver um aplicativo tambem para uma balanca jundiai, consegui ler o peso. Estou usando o MySql como BD, instalei i TCOMPORT no delphi de acordo com o video: ://youtu.be/CJbr4OZ5rKk Depois eu criei um DBEdit onde apresento o peso lido sem formatação, pra acompanhar, daí apliquei pelo botão Peso_Entrada uma rotina para salvar no campo DBEdit Peso1 que irá salvar como Peso_entrada no BD; procedure TForm1.Button1Click(Sender: TObject); begin pesocom := Copy(Edit1.Text,3,6); DBEdit15.Text := FormatFloat('0', StrToFloat(pesocom)); if (StrToInt(DBEdit15.Text)<>0)and((DBEdit16.Text)= EmptyStr) then begin DBEdit16.Text:= FormatFloat('0', StrToFloat(pesocom)); end; end; procedure TForm1.Button2Click(Sender: TObject); begin pesocom := Copy(Edit1.Text,3,6); DBEdit17.Text := FormatFloat('0', StrToFloat(pesocom)); if (StrToInt(pesocom)<>0) and ((DBEdit17.Text)= EmptyStr) then pesosaida:=StrToInt(pesocom);{variavel de peso de saida recebe o peso filtrado} DBEdit17.Text := FormatFloat('0', (Pesosaida));{Escreve Vpesosaida sem zero esquerda} pesoliq:= pesosaida-pesoentrada; {carrega o peso liquido para manipular}

Bom dia a todos. Estou precisando receber dados de uma balança. Esta balança foi aferida para funcionar apenas no modo impressão, logo ela não recebe comandos; apenas envia. Até ai tudo bem. Instalei o pacote Tcomport ou Comlib, e com ele utilizei os componentes comport e comterminal. Quando clico em impressão na balança, os dados que eu quero são gerados neste terminal virtual do componente; O problema é que eu preciso pegar esta string e utilizar como campo de um Form. Pensei então que a alternativa seria capturar o buffer desta comport. o comando deverá vim como uma string, tendo em vista que o protocolo é RS232. tentei o comando read(____,count); readStr(str,count); o segundo problema é associar a string que não sei se estou importando a um tedit ou tmemo: estava tentando da seguinte forma: form.tdeit := form.tedit + comport.____aqui não sei o que utilizo___; Se alguém puder ajudar...

Pra quem estiver precisando do componente ou apenas por curiosidade, segue o link pra baixá-lo, inclusive um tutorial de como instalar. O componente para porta serial – TcomPort, pode ser baixado na página www.jclima.tk. Estando na página principal, selecione o link para a página downloads. Selecione então o link componentes (Biblioteca TComPort) na sessão “Minicurso de Delphi”. Crie então o diretório: C:\Programs Files\Borland\Delphi7\Components\PortaSerial e salve o arquivo comprimido (Serial.zip) neste diretório. Descomprima então este arquivo. O restante está no tutorial. Um forte abraço à todos.

Possuo um controle de acesso com biometria em usb, mais devido a limitação do cabo usb de 5m, estou migrando para serial. No entanto não existe biblioteca ou sdk para desenvolvimento via serial, tudo tem que ser feito na mão mesmo. Estou utilizando o component Tcomport para comunicar com o leitor mais não tenho obtido nenhuma resposta. Confesso que estou totalmente perdido. O protocolo do leitor é o seguinte: StartByte|Comand Byte|Param1|Param2|Error/Flag|CheckSum|StopByte 1byte 1byte 4byte 4byte 1byte 1byte 1byte O inicio do pacote deve ser: Start code: 1 byte. Indicates the beginning of a packet. 0x40, corresponding to ‘@.’ O final do pacote: End code: 1 byte. LF (‘\n’, 0x0D). Indicates the end of a packet. O comado para checar o leitor: 1.Check finger Code of command|Param1| Param2 |Flag/Error 0x4B 0x00000000 0x00000000 0x00 Check and inform host if there is finger on the scanning window Return to Host 0x00 Contrast value 0x00000000 0x40 (if finger is) 0x41(if there isn’t finger ) Agora minha duvida, como faço para mandar estes valores para o leitor utilizando o Tcomport??? Já tentei simplesmente escreve-los pelo writeStr, mais não tive nenhum sucesso. Vi um modelo feito em C++, estes valores 0x00, 0x40, 0x4B, etc., são escritos no tipo byte, mais tentei escreve-los como byte, mais o delphi so reconhece o '0' inicial. Tentei como char também, tive o mesmo problema. Agradeço se alguém puder me ajudar.

Reisah, este "Start code" corresponde ao StartByte e o "End code" corresponde ao StopByte ou não há necessariamente a relação? Conforme o caso, seria possível utilizar o componente TComDataPacket associado ao TComPort e usar o evento OnRxBuf. O componente TComDataPacket permite que você identifique strings de início e fim de pacote, facilitando a leitura dos mesmos. Supondo que existam vários pacotes possíveis, bastaria configurar um componente deste para cada pacote, ligá-lo ao único TComPort e usar o evento OnPacket de cada um deles para processar o pacote quando este está completo e pronto para ser processado. Dois comentários a respeito a leitura do buffer: 1) Vejo que você fixou o tamanho em 13, mas isto pode não ser correto. Será que você sempre receberá pacotes com 13 caracteres? (está praticamente associada a pergunta inicial) Observe que o correto seria você verificar e/ou usar a quantidade de bytes que está lhe sendo entregue e isto consta no parâmetro Count. Voce não deve correr o risco de ler coisa de menos ou tentar ler coisa de mais. 2) Não estou certo quanto ao funcionamento correto deste processo, uma vez que supostamente a porta poderia retornar algum byte com valor zero no meio da string e, como sabemos, as strings são tratadas normalmente com o zero terminador. Isto resulta que se de 13 bytes o 6º for um zero, sua string a ser concatenada estará incluindo apenas 5 caracteres ao memo e o resto dos bytes recebidos estariam sendo desprezados. Como diga, sugiro que trabalhe com constantes para a identificação dos comandos e status, como por exemplo: Const cmStartCode = $40; cmEndCode = $0D; cmCheckFinger = $4B; ...ajuda bastante na leitura do código como um todo, já que você os usa no lugar do número. São coisas para você avaliar. Eu não tenho como fazer qualquer teste com porta serial e os comentários que faço são baseados em experiência passada. Apenas tenha eles em conta quando estiver fazendo seus testes. Abraços

Jhonas, acho que estou chegando perto, instalei o Tcomport e testei todas as Com1,Com2... disponíveis e não identifiquei a chegada dos dados que quando o dispositivo esta sendo usado ele oculpa uma porta que não são as "COM". Pergunta, quando um dipositivo e ligado em uma porta (exemplo 3822) essa porta fica aberta até que o dispositio seja fechado ou é aberto e fechado quando há alguma transferencia de dados? Eu criei um Scaner link que indica as portas abertas, mas como eu posso monitorar o tráfico de dados na porta eu sei como os os dados estão chegando, só não sei como pega-los.

Veja no link abaixo e clique em Datalogic ( perguntas e respostas ) Obs: ao lado tem o link para o manual do aparelho http://www.xpto.com.br/suporte_perguntas_resp_leitores.asp este modelo pega RJ45 no leitor e o mesmo cabo entra no PC como SERIAL (DB9), Talvez voce não tenha comunicação com a porta serial e precise de um componente para isso, então veja o post: http://scriptbrasil.com.br/forum/index.php...amp;hl=tcomport abraço

Eu já tentei enviar um e-mail para ele, mas é invalido: eu baixei o Tcomport para tentar ler o sinal e ficar monitorando a porta de Entrada "Com2" , mas o máximo que conseguir foi pegar apenas o "Ring" que vem antes no Número. Desta forma seria mais complicado Jhonas?

Assim; Na Unit1 (TMS8), ficou: { Private declarations } public { Public declarations } procedure ClientSocket1Read(Sender: TObject; Socket: TCustomWinSocket); end; O procedimento; procedure TMS8.ClientSocket1Read(Sender: TObject; Socket: TCustomWinSocket); var hexaRcv: string; begin HexaRcv := Socket.ReceiveText; label1.Caption:=HexaRcv; //criei este label para chekar se recebo ou não os strings end; Na Unit2 (TSetup); type TSetup = class(TForm) ComPort1: TComPort; Button1: TButton; Button2: TButton; ListBox1: TListBox; EasyRegAdvanced1: TEasyRegAdvanced; psvBorderLabel1: TpsvBorderLabel; Btn3: TButton; Btn1: TButton; OBtn1: TOvalButton; ClientSocket1: TClientSocket; edServerName: TEdit; psvBorderLabel2: TpsvBorderLabel; btnClient: TButton; Panel1: TPanel; ComboBox1: TComboBox; Button3: TButton; procedure FormCreate(Sender: TObject); procedure Btn3Click(Sender: TObject); procedure Btn1Click(Sender: TObject); procedure ComPortOpen(Sender: TObject); procedure ComPortClose(Sender: TObject); procedure OBtn1Click(Sender: TObject); procedure btnClientClick(Sender: TObject); procedure ClientSocket1Connect(Sender: TObject;Socket: TCustomWinSocket); procedure ClientSocket1Disconnect(Sender: TObject; Socket: TCustomWinSocket); procedure AtualizaEstado(Enable :Boolean); procedure Button3Click(Sender: TObject); procedure ClientSocket1Read(Sender: TObject; Socket: TCustomWinSocket);// <<<-------------------------- ...e o procedimento; procedure TSetup.ClientSocket1Read(Sender: TObject; Socket: TCustomWinSocket); begin MS8.ClientSocket1Read(Sender, Socket); end; Só que infelizmente não recebo nada!!!! Em principio esta tudo OK....sem erros! Abraço

Boa noite companheiros, Viva Micheus, Cá vai o código de acordo com a tua sugestão: Na Unit2 (Setup) unit Unit2; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, CPort, StdCtrls, ExtCtrls, CPortCtl, Registry, yupack, CPDrv, EasyRegAdvanced, psvBasiclbl, psvBorderLabel, Buttons, OvalBtn, ScktComp; type TSetup = class(TForm) ComPort1: TComPort; Button1: TButton; //(...)por aí fora . . . . procedure FormCreate(Sender: TObject); procedure Btn3Click(Sender: TObject); procedure Btn1Click(Sender: TObject); procedure ComPortOpen(Sender: TObject); procedure ComPortClose(Sender: TObject); procedure OBtn1Click(Sender: TObject); procedure btnClientClick(Sender: TObject); procedure ClientSocket1Connect(Sender: TObject;Socket: TCustomWinSocket); procedure ClientSocket1Disconnect(Sender: TObject; Socket: TCustomWinSocket); procedure AtualizaEstado(Enable :Boolean); procedure Button3Click(Sender: TObject); //procedure ClientSocket1Read(Sender: TObject; Socket: TCustomWinSocket); private { Private declarations } // procedure AtualizaEstado(Enable :Boolean); public { Public declarations } end; var Setup: TSetup; implementation uses Unit3, Unit1; {$R *.dfm} procedure TSetup.AtualizaEstado(Enable :Boolean); begin //btnEnvia.Enabled := Enable; end; procedure TSetup.FormCreate(Sender: TObject); . . . //.... (...) . . . procedure TMS8.ClientSocket1Read(Sender: TObject; Socket: TCustomWinSocket); begin MS8.ClientSocket1Read(Sender, Socket); end; ... e na Unit1 (Form principal): unit Unit1; interface uses //...(...) type TMS8 = class(TForm) . . . //...(....).... . . . procedure LBOffClick(Sender: TObject); procedure LBMenuClick(Sender: TObject); procedure LB0Click(Sender: TObject); procedure LB1Click(Sender: TObject); procedure LB2Click(Sender: TObject); procedure LB3Click(Sender: TObject); procedure LB4Click(Sender: TObject); procedure LB5Click(Sender: TObject); procedure LB6Click(Sender: TObject); procedure LB7Click(Sender: TObject); procedure LB00Click(Sender: TObject); procedure BmsXPButton1Click(Sender: TObject); procedure LB01Click(Sender: TObject); procedure LB02Click(Sender: TObject); procedure LB03Click(Sender: TObject); procedure LB04Click(Sender: TObject); procedure LB05Click(Sender: TObject); procedure LB06Click(Sender: TObject); procedure LB07Click(Sender: TObject); private { Private declarations } public { Public declarations } ClientSocket1Read(Sender: TObject; Socket: TCustomWinSocket);// de acordo com o sugerido. end; Const Header = Char($AA) +Char($55); Aud = Char($02); //audio Vid = Char($01); //video ViAu = Char($03); //video + audio Header1 = '$AA$55'; Aud1 = '$02'; //audio Vid1 = '$01'; //video ViAu1 = '$03'; var MS8: TMS8; VA :Char; //Video e/ou Audio VA1, ReceivedMsg, LBSource1, HexaId :String; LBSource :Char; StrInt, DelimiterIdx: Integer; StrString:string; StrChar:Char; implementation uses Unit2; //uses Unit3; {$R *.dfm} . . . //....(....).... . . . . procedure TMS8.ClientSocket1Read(Sender: TObject; Socket: TCustomWinSocket);// de acordo com a tua sugestão. var ReceivedCmd :String; begin ReceivedCmd := Socket.ReceiveText; end; Espero que seja o suficiente para a análise em questão. Aquele abraço José Da Silva

Sobre o Comport do Dejan, o usu é simples... basta monitorar o que "cai" na serial... Se você colocou um componente no seu form (por exemplo, GPS = TComPort), observe seu evento OnRxChar... StrComB := 'COM2'; Count := 0; GPS.ReadStr(StrComB, Count); sDados := sDados+StrComB; {sDados é uma variável global, que vai acumulando toda a leitura serial até encontrar um CR} iPosCr := Pos(CHR(13),sDados); IF iPosCr>0 then Begin ShowMessage('Recebi isto pela serial: '+sDados+'!'); {Aqui, faço o que quiser com o conteúdo recebido e depois esvazio a variável sDados} End; {EndIf iPosCr>0} Cuidados com as seriais... Como citei anteriormente, uso o componente em situações críticas... por exemplo, o mesmo programa lê uma porta que recebe uma informação por segundo (de um GPS Etrex Garmin) e até doze informações por segundo (de um Odômetro NiteStar)... O fato é que eles não param de enviar as informações... Assim, o programa precisa ficar lendo os dados o tempo todo, para não perder informação... Então, principalmente no caso do odômetro, os dados chegam de forma muito variada, com vários blocos numa mesmo strintg... mais ou menos assim: velocidade+distância+cr+velocidade+distància+cr+velocidade distância+cr+velocidade+distância+cr+velocidade+distância+cr+velocidade+distância cr+velocidade distância+cr+velocidade+distância+cr Então, preciso manter aquela variável global (sdados) bem controlada, pois não processo todo o seu conteúdo de uma só vez... Já quando utilizamos o componente para uma leitura estática (por exemplo, leitura da pesagem da balança conectada ao pdv em um mercado), é mais simples, pois vou "ler" somente uma string, de uma só vez, processar seu peso ou valor e pronto... Então, muito cuidado quando a leitura pela serial for de um fluxo contínuo de informações... Ok?
