Re: Tiny RTC DS1307 + 24C32 Real Time Clock Module (HCMODU00

I have tried connecting both the pins SDA1 and SDA2 and the pins 20 and 21. In both cases I have used adafruit 4 bit converter BSS138, with LV at 3,3V and HV at 5V. I have also tried using a 1.8KOhm pull-up resistors on SDA and SCL lines, but without success.

Re: Tiny RTC DS1307 + 24C32 Real Time Clock Module (HCMODU00

Hi, I'm quite new to arduino due and I'm trying to use the HCMODU0011 module on it. I have provided 5V power supply and made the connections to SDA and SCL using a logic level converter suitable for I2C (just to be sure 5V is used instead of 3.3V). Unfortunately, loading the example here reported no...
