[SOLVED] ds3231 I2C1_Wr Issue

[djeceymca]

In proteus, I could not find DS3231 so i used DS1307 and surprisingly it works in proteus.

In real hardware i am using DS3231 and that where my code get stuck.

Then change the DS3231 module and try.

Hello Okada,

Issue is solved now.
I just needed to set port as Digital by setting ANSELX bits.
Thanks a lot again for your help.
