Beste Rob (robtillaart),
Bedankt voor je reactie. Het script ben ik naar aanleiding van je advies opnieuw aan het maken. De basis was al totaal anders, zodoende.
In de logbestanden (buffer) op de SD card zit de tijd nog niet verwerkt. Als ik de buffer op later tijdstip zou versturen naar db, is er niet meer bekend hoe laat de ernergie verbruikt is. Nu worden alle pulsen direct verwerkt, de tijd laat ik door PHP in de DB plaatsen.
Helaas loop ik al vast om de Arduino middels ntp de tijd op te laten halen (bij interne server of ntp op internet).
Zie bijgaand mijn code tot nu toe.
#include <Time.h>
#include <SD.h>
#include <SPI.h>
#include <Dhcp.h>
#include <Dns.h>
#include <Ethernet.h>
#include <EthernetClient.h>
#include <EthernetServer.h>
#include <EthernetUdp.h>
#include <util.h>
//int getNtpTime;
byte mac[] = { 0x90, 0xA2, 0xDA, 0x00, 0x60, 0xD6 };
byte ip[] = { 192, 168, 1, 50 }; // Arduino IP-address.
byte gateway[] = { 192, 168, 1, 254 };
byte subnet[] = { 255, 255, 0, 0 };
byte server[] = { 192, 168, 1, 2 }; // Database server address.
//byte getNtpTime[] = { 192, 168, 1, 1 }; // NTP server address.
EthernetClient client;
void setup(){
Ethernet.begin(mac, ip, subnet, gateway);
Serial.begin(9600);
Serial.println("waiting for sync");
setSyncProvider(getNtpTime);
while(timeStatus()== timeNotSet); // wait until the time is set by the sync provider
delay(1000);
}
void loop(){
if (client.connect(server, 80)) {
Serial.println("Connected");
}else{
Serial.println("Connection failed");
}
if( now() != prevDisplay) //update the display only if the time has changed
{
prevDisplay = now();
digitalClockDisplay();
}
}
void printDigits(int digits){
// utility function for digital clock display: prints preceding colon and leading 0
Serial.print(":");
if(digits < 10) {
Serial.print('0');
Serial.print(digits);
}
}
void digitalClockDisplay(){
// digital clock display of the time
Serial.print(hour());
printDigits(minute());
printDigits(second());
Serial.print(" ");
Serial.print(day());
Serial.print(" ");
Serial.print(month());
Serial.print(" ");
Serial.print(year());
Serial.println();
}
Heb jij enig idee wat ik mis doe? De volgende foutmelding blijf ik houden, bij verify code.
sketch_apr29a.cpp: In function 'void setup()':
sketch_apr29a:26: error: 'getNtpTime' was not declared in this scope
sketch_apr29a.cpp: In function 'void loop()':
sketch_apr29a:38: error: 'prevDisplay' was not declared in this scope
Heb getNtptime al als byte (ip) geprobeerd op te geven ook variable voor url? p.s. ben nog een echte beginner. Met veel script voorbeelden (examples) lukt het soms een klein beetje.
Het volgende script heb ik momenteel draaien. Erg simpel als de LED (kwh_meter) knippert stuur ik dit direct naar de PHP webserver.
