To interface DS3231 with ESP32, you need to install theRTClib libraryfirst. After installing this Adafruit RTC library, you can connect your ESP32 board with DS3231 using the I2C protocol. To connect ESP32 I2C with the RTC DS3231 module, you can use the ESP32 D21 and D22 pins. 2.1....
A big perk for using Arduino Due is its higher processor performance compared to simple 8-bit microcontrollers. The Due’s ARM Cortex-M3 CPU enables it to work at a much faster speed than most other Arduino boards. This makes the Due great for projects that need powerful processing or real...
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...

This example demonstrates the usage of the real-time clock (RTC) in Infineon MCU. It shows how to get and set the time in the RTC using the RTC HAL API. The example also supports the daylight saving time (DST) feature. A UART interface is used to input the time and configure the ...
The best trick to get extra inputs into the ESP8266-01 is to use an I2C interface. One choice is to use GPIO0 and GPIO2 as the I2C bus. The pullup resistors needed to get the module to start up correctly can double as the I2C bus pull-up resistors and the other, slave, componen...
The BackUp Registers are part of the RTC peripheral so we will need to enable the RTC to be able to access them.In Pinout & Configuration Tab, go to Timers, and select RTC and then in the RTC Mode and Configuration. Activate the clock source to enable the RTC. ...
Pin1:VDDA is a power pin for analog power ranges from 2.5V to 3.6V. Pin2:LNA is an input/output pin specifically used for RF antenna interface. Chip produces impedance of 39+j6 Ω. Pin3:VDD3P3 is a power pin to provide amplifier power ranges from 2.5V to 3.6V. ...
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...
