Hi,
I follow this post https://www.b4x.com/android/forum/threads/i2c-address-scanner.75815/#content using esp32 to scan i2c address, but can't find the address.
I connect ds1307 sda to esp32 pin 21 and scl to pin 22, but fail to find address.
But I use wemos d1 or arduino uno can found address 0x68.
Anyone using esp32 with ds1307 before?
How can solve this problem?
