Hello,
I received a KC868-A6 few days ago. I have been able to read and write both PCF8574 but I’m having issues with the DS1307. I tried to load a I2C scanner and both PCF8574 are seeing (0x22H, 0x24H) but the DS1307 doesn’t.
I have tried to check with my logic analyzer that the I2C signal is arriving to the DS1307 trough the MOSFET transistors and signal is Ok but there is no answer while scanning the I2C bus nor trying to read it.
Any ideas what could be happening?
