Salve a tutti,
ho un piccolo problemino quando mando i dati che recupero in Modbus da un contatore.
unsigned int readRegs1[30];
unsigned int readRegs2[34];
unsigned int readRegs3[59];
unsigned int readRegs4[59];
unsigned int readRegs5[59];
unsigned int readRegs6[59];
unsigned int readRegs7[59];
unsigned int readRegs8[59];
unsigned int readRegs9[44];
SimpleTimer timer;
float Voltage =0;
float Current =0;
float PowerFactor =0;
float ActivePower =0;
float Frequency =0;
float ActiveEnergy =0;
void setup()
{
pinMode(SS_PIN, OUTPUT);
digitalWrite(SS_PIN, HIGH);
pinMode(10, OUTPUT); // Set the CS pin as an output
digitalWrite(10, 1); // Turn off the W5100 chip! (wait for configuration)
pinMode(4, OUTPUT); // Set the SDcard CS pin as an output
digitalWrite(4, 1); // Turn off the SD card! (wait for configuration)
Wire.begin();
Serial.begin (9600);
timer.setInterval(30000, RepeatTask);
modbus_construct(packet1, 1, READ_HOLDING_REGISTERS, 0, 30, readRegs1);
modbus_construct(packet2, 1, READ_HOLDING_REGISTERS, 31, 34, readRegs2);
modbus_construct(packet3, 1, READ_HOLDING_REGISTERS, 256, 59, readRegs3);
modbus_construct(packet4, 1, READ_HOLDING_REGISTERS, 316, 59, readRegs4);
modbus_construct(packet5, 1, READ_HOLDING_REGISTERS, 512, 59, readRegs5);
modbus_construct(packet6, 1, READ_HOLDING_REGISTERS, 572, 59, readRegs6);
modbus_construct(packet7, 1, READ_HOLDING_REGISTERS, 768, 59, readRegs7);
modbus_construct(packet8, 1, READ_HOLDING_REGISTERS, 828, 59, readRegs8);
modbus_construct(packet9, 1, READ_HOLDING_REGISTERS, 1024, 44, readRegs9);
modbus_configure(&Serial1, baud, SERIAL_8N1, timeout, polling, retry_count, TxEnablePin, packets, TOTAL_NO_OF_PACKETS);
Per metterli in assieme ho fatto queste funzioni:
unsigned long Compact3Word(int FirstWord, unsigned int Array[])
{ int a = FirstWord, b = FirstWord + 1, c = FirstWord + 2;
unsigned long dataA =0, dataB =0;
dataA = Array[b] + (Array[a] * 0x10000);
dataB = Array[c] + (dataA * 0x10000);
return dataB;
}
unsigned long Compact2Word(int FirstWord, unsigned int Array[])
{ int a = FirstWord, b = FirstWord + 1;
unsigned long dataC =0;
dataC = Array[b] + (Array[a] * 0x10000);
return dataC;
}
Dopo diché prima di spedirle al Server :
//Create Data to Emoncms.org
Voltage = (Compact2Word(12,readRegs1))/1000;
Current = (Compact2Word(22,readRegs1))/1000;
PowerFactor = readRegs1[27]/1000;
ActivePower = Compact3Word(6,readRegs2);
Frequency = readRegs2[33]/100;
ActiveEnergy = (Compact3Word(9,readRegs3))/1000;
//send values
sendData();
Serial.println(Voltage);
Serial.println(Current);
Serial.println(PowerFactor);
Serial.println(ActivePower);
Serial.println(Frequency);
Serial.println(ActiveEnergy);
La trasmissione funziona ma sul Serial Monitor e sul Server ho questi risultato, la prima trama sono tutti i dati ricomposti e stampati senza messa in forma (ho colorato quelli che ritocco):
231014;2595;955;572791;599527;16260;49980;522940;0;303276;0;196608;0;37111;0;0;0;522942;0;303278;0;196608;0;37111;0;0;0;0;0;0;0;0;0;0;0;0;0;522910;0;303274;0;0;0;0;0;0;0;522939;303274;259802;37111;4294901760;16/12/14;16:55:0

Come mai ho solo degli 00 dopo il punto?
