![]() I also tried using A4 and A5 instead of SDA and SCL pins. ![]() The error occurs in the third line (rtc (SDA,SCL)) - I have checked the pins and switched the battery on the chip. Rtc.setDate(1, 1, 2014) // Set the date to January 1st, 2014 cpp files - you have to have the include directive explicitly. Rtc.setTime(12, 0, 0) // Set the time to 12:00:00 (24hr format) ino file, the arduino IDE adds a bunch of standard includes, one of them containing the definition of uint8t. Rtc.setDOW(WEDNESDAY) // Set Day-of-Week to SUNDAY I found a simple code online to test the chip but when I upload it the following error shows up: "no matching function for call to 'DS3231::DS3231(const uint8_t&, const uint8_t&)" #include If the volatile variable is bigger than a byte (e.g. Multiple libraries (Rinky-Dink, ds3231-master) but nothing works. ![]() THIS LIBRARY MIGHT NOT BE COMPATIBLE WITH EXISTING SKETCHES. I found online a lot of library issues, i tried using The library allows to control I2C displays with functions extremely similar to LiquidCrystal library. 't' stands for 'type. Im currently stuck with the DS3231 (zs-042) chip. So, in the C99 standard (the ISO standard for the C language), types that are designed to be cross-platform compatible are marked with a 't'. I am building a arduino based bicycle speedometer with time and temperature display.
