Timers don't work [SOLVED]

Hello,

The timers connected on the PCF 8575 Don't work.I can switch them on or off on the ferduino but the output of the PCF8575 stays high.
I tried to use the instruction on this topic but then my clock and date get strange (time 27:85:85).

Hi!

Try change the pins of the RTC as I told here.

Best regards.

Hi,

Maybe a stupid question, but how do i change the pins Because my RTC is on the tft shield.Just rewire pin 20/21 of the tft shield to 18/19?
And thats all of do i have to change something in the sketch after that.

Hi!

Move the pins 20 and 21 to 18 and 19.

Make a bypass like this:

Change on code:

Code: Select all

DS1307 rtc(20, 21);

to:

Code: Select all

DS1307 rtc(18, 19);

Best regards.

Hi.
Clock is working pin 20/21 from the tft shield are not connected anymore .On the topside i made the bypass to pins 18/19.
But still the output of the PCF8575 stays high when timer actived or deactived.I changed the code to use the PCF8575, but i think i do something wrong.

Best regards.

Hi ,

i tried that in the serial monitor theres only a $ and the led on the pcf8575 board glows a bit nothing more.

Change the baud on serial monitor to 38400 and

Code: Select all

delay(100);

to

Code: Select all

delay(2000);

Hi,

when loaded the test code the relais switch on and off so that is working fine.
But when the complete code loaded i can switch them on or off in the screenn but the relais won't switch on or off.

Hi,

You sugeested to uncomment the next lines.
https://github.com/FernandoGarcia/Fedui ... a.ino#L843
and add

Code: Select all

PCF8575 PCF8575;


after

Code: Select all

byte endereco_PCF8575TS = 0x20; // Endereço em hexadecimal = 0x20


is it correct to uncomment the line because in the text after that line "Change to "false" If you do not have a PCF8575"?Or do i change false to true?

this is now the code after adding PCF8575 PCF8575; to that line. Is this correct?

Code: Select all

//*****************************************************************************************
boolean PCF8575TS_S = false; // Altere para "false" caso não tenha um PCF8575
byte endereco_PCF8575TS = 0x20; // Endereço em hexadecimal = 0x20
PCF8575 PCF8575;


//*******

Hi!

It's right.

Change:

Code: Select all

boolean PCF8575TS_S = false;

To:

Code: Select all

boolean PCF8575TS_S = true;

Best regards.
