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).
Len
DS1307 rtc(20, 21);
DS1307 rtc(18, 19);
delay(100);
delay(2000);
PCF8575 PCF8575;
byte endereco_PCF8575TS = 0x20; // Endereço em hexadecimal = 0x20
//*****************************************************************************************
boolean PCF8575TS_S = false; // Altere para "false" caso não tenha um PCF8575
byte endereco_PCF8575TS = 0x20; // Endereço em hexadecimal = 0x20
PCF8575 PCF8575;
//*******
boolean PCF8575TS_S = false;
boolean PCF8575TS_S = true;
