Installed SHAKTI supported boards in Arduino IDE.Ĭonnect Arty and DS3231 according to the below diagram,.Arty7 35t/100t board with either pinaka, parashu or vajra programmed.

The device incorporates a battery input and maintains accurate timekeeping when the main power to the device is interrupted.Īlso check out this article DS3231 on Shakti Processor. The DS3231 RTC module Precise Real-Time Clock Module is a low-cost, extremely accurate I☬ real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. In this tutorial we are going to use the DS3231 module. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic device which needs to keep accurate time. I2C-Data-Frame:Ī real-time clock (RTC) is an electronic device (most often in the form of an integrated circuit) that measures the passage of time. Also, the clock signal is always controlled by the master. Like SPI, I2C is synchronous, so the output of bits is synchronized to the sampling of bits by a clock signal shared between the master and the slave. I2C is a serial communication protocol, so data is transferred bit by bit along a single wire (the SDA line). SCL (Serial Clock) – The line that carries the clock signal.SDA (Serial Data) – The line for the master and slave to send and receive data.Like UART communication, I2C only uses two wires to transmit data between devices, This is really useful when you want to have more than one micro controller logging data to a single memory card or displaying text to a single LCD. With I2C, you can connect multiple slaves to a single master (like SPI) and you can have multiple masters controlling single, or multiple slaves. I2C combines the best features of SPI and UART protocol. It is widely used for attaching lower-speed peripheral ICs to processors and micro controllers in short-distance, intra-board communication. I2C ( Inter-Integrated Circuit) pronounced I-squared-C or I-two-C, is a synchronous, multi-master, multi-slave, packet switched, single-ended, serial communication bus invented in 1982 by Philips Semiconductor (now NXP Semiconductors).
