Android'de rs485 bağlantısını denedim. Ben mod kütüphane jamod, android4j ...Android Studio Modbus rs485 seri bağlantısı MacosX
kullandı ama hepsi çalışmıyor.
İlk Dene:
Ben kodlarını deneyin ModbusFactory fabrika = new ModbusFactory(); SerialParameters params = yeni SerialParameters(); params.setCommPortId (path_serial); params.setBaudRate (Baud_Rate); params.setDataBits (8); params.setStopBits (1); params.setParity (0); ModbusMaster master = fabrika.createRtuMaster (params); master.setTimeout (1000); master.setRetries (0); long start = System.currentTimeMillis();
String portname = "/dev/ttyS3"; int baud = 57600; //check params // open the serial communications port SerialParameters params = new SerialParameters(); params.setPortName(portname); params.setBaudRate(Baud_Rate); params.setDatabits(8); params.setParity("None"); params.setStopbits(1); params.setEncoding(Modbus.SERIAL_ENCODING_RTU); params.setEcho(false); con = new SerialConnection(params); try { con.open(); } catch (Exception ex) { } çalışmıyor
SerialConnection con = null; // the connection
ModbusSerialTransaction trans = null; // the transaction
//ReadInputRegistersRequest req = null; // the request
ReadHoldingRegistersRequest req = null;
ReadHoldingRegistersResponse res = null;
//ReadInputRegistersResponse res = null; // the response
String portname = null; // the name of the serial port to be used
int unitid = 0; // the unit identifier we will be talking to
int ref = 0; // the reference, where to start reading from
int count = 0; // the count of IR's to read
int repeat = 1; // a loop for repeating the transaction
try {
portname = path_serial;
//System.setProperty("gnu.io.rxtx.SerialPorts", portname);
unitid = 2;
ref = 0;
count = 4;
} catch (Exception ex) {
ex.printStackTrace();
System.exit(1);
}
// 2. Set master identifier
// ModbusCoupler.createModbusCoupler(null);
ModbusCoupler.getReference().setUnitID(1);
// 3. Setup serial parameters
SerialParameters params = new SerialParameters();
params.setPortName(portname);
params.setBaudRate(Baud_Rate);
params.setDatabits(8);
params.setParity("None");
params.setStopbits(1);
params.setEncoding("rtu");
params.setEcho(false);
// 4. Open the connection
con = new SerialConnection(params);
try {
con.isOpen();
// con.open();
}catch (Exception ex) {
}
con.close();

İkinci Çalışmıyor
try {
master.init();
} catch (ModbusInitException e) {
System.out.println("Modbus Master Init Error: " + e.getMessage());
return;
}
try {
byte [] RIR,RHR,RDI,RCR;
int slaveId=1;
int startOffset=0;
int numberOfRegisters=10;
int numberOfBits=10;
ReadHoldingRegistersRequest reqRHR = new ReadHoldingRegistersRequest(slaveId, startOffset, numberOfRegisters);
ReadHoldingRegistersResponse resRHR = (ReadHoldingRegistersResponse) master.send(reqRHR);
RHR=resRHR.getData();
System.out.println("HoldingRegister :" + RHR);
//System.out.println("Reg. 1001 Value:" + master.getValue(7, RegisterRange.HOLDING_REGISTER, 1000, DataType.FOUR_BYTE_FLOAT_SWAPPED));
// more like the above until all required register values are read.
// ..
} catch (ModbusTransportException e) {
e.printStackTrace();
} finally {
master.destroy();

Bu sorunun kimsenin bilgisi yok mu? – Jealian
Modbus RS485 portunu android yapan hiç kimse oldu mu? Lütfen yardım edin:/ – Jealian
Sanırım sorunun ne olduğunu biliyorum. Sorunu bulduğumda yazacağım .. Kimsenin anlamadığını düşünüyorum :) – Jealian
