New RTC-Library for the Due [Now inside the Library Manager too] Version 1.1.0

-

hello,

i have rewritten rtc-library [now version 1.1.0] due function-calls similar or more other rtc-librarys (like ds1307 or rtczero), , btw. add support timezone-library jchristensen kapyaar idea, cleaned code , grab lines rtczero , add more comments , new examples.

i hope can enjoy new version old 1 still available, wouldn't neat after this.

my impulse rewrite make easyer migrate or due.

link home of new lib, direct link.

now inside library manager too.

sorry bad named zip.

have checked , verified library returns time_t correctly unixtime?

here's problem i've encountered.   i'm using rtc_clock library in data logger.   i push collected data database , join sets of data based on unixtime stamps.   i noticed there large time shift between data various boards.   the due rtc library "rtc_clock.unixtime()"  returns value 35 days future.!!!

here example comparison:

**** time: 19:19:27.406   date: 14/8/2016  fix: 1 quality: 2  location: 47xxxxxn, 12xxxxxw  speed (knots): 0.01 angle: 17.08 altitude: 80.70 satellites: 7
gps unixtime: 46 1471202367  rtc_unixtime: 1474201121

if plug gps unixtime value of online converters time... correctly returns date 14/8/2016 , correct time (utc).

but rtc time value 1474201121 when converted returns data

http://www.unixtimestamp.com/index.php

1474201121
is equivalent to:

09/18/2016 @ 12:18pm (utc)
2016-09-18t12:18:41+00:00 in iso 8601

sun, 18 sep 2016 12:18:41 +0000 in rfc 822, 1036, 1123, 2822

if use rtc library pull hour, minute, seconds, day, month, year... resulting text appears reasonable - e.g.  conversion internal data human values uses same algorthim ... conversion unixtime incorrect.

sunday, 18-sep-16 12:18:41 utc in rfc 2822

Valutazione Template - Joomla! Forum - community, help and support

salve, prima di installare joomla, vorrei porvi tre semplici domande: 1) l'ultima versione in italiano di joomla, supporta questo template prodotto da gavik? loro scrivono che non è un semplice template, ma una vera e propria suite, ma vorrei una vostra opinione. qui sono descritte le funzioni della suite. 2) per sfruttare gli elementi che si vedono nella pagina, ad esempio quello in alto sinistra dove scorrono le notizie, occorre installare qualche componente aggiuntivo? 3) futuri upgrade alla piattaforma joomla, potranno inficiare il funzionamento o la compatibilità del template? vi ringrazio anticipatamente della disponibilità. 1) non vedo nulla di particolare se non una miriade di posizioni per blocchi 2) è un modulo se non sbaglio pagamento, ma adesso non ricordo bene 3) no. ti ricordo che devi installare joomla  1.0.12 Board index Joomla!

SD Datastring Convention

-
i wondering if there preferred convention appending data logged?  see standard sd example uses: code: [select] void loop() {   // make string assembling data log:   string datastring = "";   // read 3 sensors , append string:   (int analogpin = 0; analogpin < 3; analogpin++) {     int sensor = analogread(analogpin);     datastring += string(sensor);     if (analogpin < 2) {       datastring += ",";     }   } creating string called datastring, , appending it, have seen in forums string not liked.  around this, code data logging looks this: code: [select] void sdupdate() {   datetime = rtc.now();   unsigned int hour = now.hour();   unsigned int minute = now.minute();   unsigned int second = now.second();   char datastring[100] = "";   char char_current_pay[15] = "";   char char_overall_pay[15] = ""; ...

First use of Arduino Uno : avrdude error on Blink uploading

-
hi all, i bought arduino (or should genuino) starter kit. first test , failing. i have follow religiously first pages , when trying upload blink sketch, uploading fails avrdude error : avrdude: stk500_recv(): programmer not responding. as suggested in other posts, have tried 1) switch latest hourly build of arduino ide 2) switch previous stable version of arduino ide (1.6.09) 3) change usb cable 1 know working fine 4) make same steps on computer (unfortunatelly, of them macos running on macos 10.11.6, not interesting test) 5) press reset before upload, interesting thing : tx led never flashes the full log attached. idea of why happening ? to save people having download log, it's sync error, resp=0x00 every time: code: [select] avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 avrdude: stk500_recv(): programmer not responding and he's running 1.6.11 hourly avrdude 6.0.1. ...
