Build environment: Linux Mint 20 x86_64
Target device: ESP32 NodeMCU
ESPIDF version: v4.4

Description

This is a basic driver for the NXP RTC PCF85063A for ESP32 using ESP-IDF, it also contains a simple example using the PCF85063A driver and some timing manipulations. Hope it helps :)

Reproduce steps

Check out your I2C_MASTER_CLK and change SDA, SCL pins if necessary in the PCF85063A.h file , as follows:

#define SDA_PIN         21
#define SCL_PIN         22
#define I2C_MASTER_CLK  100000

To run this example, make sure you have ESP-IDF installed and run the command:

idf.py build flash monitor
