i try to interface DS1307 with pic32mx470f512l using Soft i2c library in micro32 lib. but no response at all the configuration as this
DEVCFG3 : $1FC02FF0 : 0xF0070000
DEVCFG2 : $1FC02FF4 : 0x00008074
DEVCFG1 : $1FC02FF8 : 0x0354C603
DEVCFG0 : $1FC02FFC : 0x110FF01B
the micro all other process very well
note
1-external osc 20mHz.

// Software I2C connections
sbit Soft_I2C_Scl at RG12_bit;
sbit Soft_I2C_Sda at RG14_bit;
sbit Soft_I2C_Scl_Direction at TRISG12_bit;
sbit Soft_I2C_Sda_Direction at TRISG14_bit;
// End Software I2C connections
i try to change the micro to pic32mx460F512L it work very well with DS1307 also my main
