DS3231 works using the I2C protocol. At the heart of this RTC module, we have the accurate RTC chip designed by Maxim. This chip handles all the time functions and communicates using the I2C with ESP32 or Arduino board. The main pins of RTC DS3231 modules are: VCC:Connect this pin to...
The STM32’s integrated RTC (Real-Time Clock) peripheral can be used to periodically wake it up from one of the various Low Power modes. It is very common for battery powered applications to have a power scheme where the application will run for a short period of time and...
It comes with everything required to support the microcontroller. To get started, you only need a micro USB cable to connect it to a computer. It can also be readily mounted on a breadboard thanks to its physical factor. Arduino Due The Due, unlike the previous boards which all used simpl...
Once we connect the module we need to program the Arduino Board to work with the Real Time Clock. However, when it comes to programing a communication between Arduino and an I2C module the code isn’t that small and easy. Luckily, there are already several libraries for the DS3231 RTC wh...
We need to enable the RTC clock as the Backup Registers are part of the RTC. This is done on RTC Configuration Function. To read a Backup Register use the HAL function call, HAL_RTCEx_BKUPRead. To be able to write to the Backup register: ...

we have to redefine the pins. Because default pins of UART1 such as GPIO9 and GPIO10 are internally connected to the SPI flash memory. Also, on some ESP32 boards, they are even exposed on the pinout headers. Hence, we can not use UART2 directly without reassigning pins in Arduino IDE...
If 4) does not fix it, uplug USB cable from PC, close Arduino IDE, open Arduino IDE, plug USB cable back in. When you apply power to the ESP8266, after grounding GPIO0, make sure it is applied cleanly. Don't jiggle the connection. The ESP8266 led should just come on and stay ...
