rtc ds 3231 starts giving wrong time after some time with esp32 wrover-b using freertos #3704
Description
Hardware:
Board: ESP32 wrover-b
IDE name: Arduino IDE 1.8.11
Flash Frequency: 80Mhz
PSRAM enabled: no
Upload Speed: 921600
Computer OS: Windows 10
hi,
I m using three sensors on i2c and rtc ds3231 ,to divide tasks I m using freertos .using esp32 in AP mode, and also in station mode so it sends weather information to my website and a webpage by AP mode, but my rtc starts showing wrong time after some time which is out of time format.
Sorry for my mistakes i m very new with this things and this is my first post.
Thanks and regards.
